Tanzania

flag of Tanzania

Tanzania, East African country situated just south of the Equator. Tanzania was formed as a sovereign state in 1964 through the union of the theretofore separate states of Tanganyika and Zanzibar. Mainland Tanganyika covers more than 99 percent of the combined territories’ total area. Mafia Island is administered from the mainland, while Zanzibar and Pemba islands have a separate government administration. Dodoma, since 1974 the designated official capital of Tanzania, is centrally located on the mainland. Dar es Salaam, however, remains the seat of most government administration, as well as being the largest city and port in the country.

Land

• Tanzania mainland

The Tanzania mainland is bounded by Uganda, Lake Victoria, and Kenya to the north, by the Indian Ocean to the east, by Mozambique, Lake Nyasa, Malawi, and Zambia to the south and southwest, and by Lake Tanganyika, Burundi, and Rwanda to the west.

• Relief

Except for the narrow coastal belt of the mainland and the offshore islands, most of mainland Tanzania lies above 600 feet (200 metres) in elevation. Vast stretches of plains and plateaus contrast with spectacular relief features, notably Africa’s highest mountain, Kilimanjaro (19,340 feet [5,895 metres]), and the world’s second deepest lake, Lake Tanganyika (4,710 feet [1,436 metres] deep).

The East African Rift System runs in two north-south-trending branches through mainland Tanzania, leaving many narrow, deep depressions that are often filled by lakes. One branch, the Western Rift Valley, runs along the western frontier and is marked by Lakes Tanganyika and Rukwa, while the other branch, the Eastern (or Great) Rift Valley, extends through central Tanzania from the Kenyan border in the region of Lakes Eyasi, Manyara, and Natron south to Lake Nyasa at the border with Mozambique. The central plateau, covering more than a third of the country, lies between the two branches.

Highlands associated with the Western Rift Valley are formed by the Ufipa Plateau, the Mbeya Range, and Rungwe Mountain in the southwestern corner of the country. From there the southern highlands run northeastward along the Great Rift to the Ukuguru and Nguru mountains northwest of Morogoro. Extending from the northern coast, the Usambara and Pare mountain chains run in a southeast-to-northwest direction, culminating in Kilimanjaro’s lofty snow-clad peak and continuing beyond to Mount Meru (14,978 feet [4,565 metres]). Immediately to the west of Mount Meru, another chain of mountains begins, which includes the still-active volcano Ol Doinyo Lengai and the Ngorongoro Crater, the world’s largest caldera, or volcanic depression. This chain extends through a corridor between Lake Eyasi and Lake Manyara toward Dodoma.

• Drainage

Because of its numerous lakes, approximately 22,800 square miles (59,000 square km) of Tanzania’s territory consists of inland water. Lake Victoria, which ranks as the world’s second largest freshwater lake, is not part of the Rift System. Although Tanzania has no big rivers, it forms the divide from which the three great rivers of the African continent rise the Nile, the Congo, and the Zambezi, which flow to the Mediterranean Sea, the Atlantic Ocean, and the Indian Ocean, respectively. Separated by the central plateau, the watersheds of these rivers do not meet.

All of Tanzania’s major rivers the Ruvuma, the Rufiji, the Wami, and the Pangani drain into the Indian Ocean. The largest, the Rufiji River, has a drainage system that extends over most of southern mainland Tanzania. The Kagera River flows into Lake Victoria, whereas other minor rivers flow into internal basins formed by the Great Rift Valley. With so many rivers, mainland Tanzania is rich in hydroelectricity potential.

• Soils

The variety of soils in mainland Tanzania surpasses that of any other country in Africa. The reddish brown soils of volcanic origin in the highland areas are the most fertile. Many river basins also have fertile soils, but they are subject to flooding and require drainage control. The red and yellow tropical loams of the interior plateaus, on the other hand, are of moderate-to-poor fertility. In these regions, high temperatures and low rainfall encourage rapid rates of oxidation, which result in a low humus content in the soil and, consequently, a clayey texture rather than the desired crumblike structure of temperate soils. Also, tropical downpours, often short in duration but very intense, compact the soil; this causes drainage problems and leaches the soil of nutrients.

• Climate

Mainland Tanzania can be divided into four principal climactic and topographic areas: the hot and humid coastal lowlands of the Indian Ocean shoreline, the hot and arid zone of the broad central plateau, the high inland mountain and lake region of the northern border, where Mount Kilimanjaro is situated, and the highlands of the northeast and southwest, the climates of which range from tropical to temperate. Tanzania’s warm equatorial climate is modified by variations in elevation. The high amount of solar radiation throughout the year is associated with a limited seasonal fluctuation of temperature: the mean monthly variation is less than 9 °F (5 °C) at most stations. Ground frosts rarely occur below 8,200 feet (2,500 metres).

Rainfall is highly seasonal, being influenced greatly by the annual migration of the intertropical convergence zone. Roughly half of mainland Tanzania receives less than 30 inches (750 mm) of precipitation annually, an amount considered to be the minimum required for most forms of crop cultivation in the tropics. The central plateau, which receives less than 20 inches (510 mm) per year on average, is the driest area and experiences a single rainy season between December and May. Precipitation is heavier on the coast, where there are two peaks of precipitation: October–November and April–May. The offshore islands and many highland areas have high annual precipitation totals of more than 60 inches (1,520 mm).

• Plant and animal life

Forests grow in the highland areas where there are high levels of precipitation and no marked dry season. The western and southern plateaus are primarily miombo woodland, consisting of an open cover of trees, notably Brachystegia, Isoberlinia, Acacia, and Combretum. In areas of less precipitation, bushland and thicket are found. In the floodplain areas, wooded grassland with a canopy cover of less than one-half has been created by poor drainage and by the practice of burning for agriculture and animal grazing. Similarly, grassland appears where there is a lack of good drainage. For example, the famous Serengeti Plain owes its grasslands to a calcrete, or calcium-rich hardpan, deposited close to the surface by evaporated rainwater. Swamps are found in areas of perennial flooding. Desert and semidesert conditions range from an alpine type at high elevations to saline deserts in poorly drained areas and arid deserts in areas of extremely low precipitation.

Because of the historically low density of human settlement, mainland Tanzania is home to an exceptionally rich array of wildlife. Large herds of hoofed animals—wildebeests, zebras, giraffes, buffalo, gazelles, elands, dik-diks, and kudu are found in most of the country’s numerous game parks. Predators include hyenas, wild dogs, and the big cats lions, leopards, and cheetahs. Crocodiles and hippopotamuses are common on riverbanks and lakeshores. The government has taken special measures to protect rhinoceroses and elephants, which have fallen victim to poachers. Small bands of chimpanzees inhabit Gombe National Park along Lake Tanganyika. Nearly 1,500 varieties of birds have been reported, and there are numerous species of snakes and lizards. In all, about one-fourth of Tanzania’s land has been set aside to form an extensive network of reserves, conservation areas, and national parks, a number of which including Serengeti National Park, the Selous Game Reserve, the Ngorongoro Conservation Area, and Kilimanjaro National Park have been designated UNESCO World Heritage sites.

Zanzibar and Pemba

• Relief and drainage

The islands of Zanzibar and Pemba are located in the Indian Ocean. Zanzibar is 22 miles (35 km) off the coast of mainland Tanzania; Pemba, 35 miles (56 km). Low-lying Pemba, whose highest point reaches an elevation of 311 feet (95 metres), and Zanzibar, which reaches 390 feet (119 metres), are islands whose structure consists of coralline rocks. The west and northwest of Zanzibar consist of several ridges rising above 200 feet (60 metres), but nearly two-thirds of the south and east are low-lying. Pemba appears hilly because the level central ridge has been gullied and eroded by streams draining into numerous creeks. On Zanzibar Island short streams drain mostly to the north and west. The few streams in the east disappear into the porous coralline rock.

• Soils

Among the 10 types of soils recognized in Zanzibar are fertile sandy loams and deep red earths, which occur on high ground; on valley bottoms, less-fertile gray and yellow sandy soils are found. The eight soil types in Pemba include brown loams; pockets of infertile sands are found on the plains.

• Climate

Zanzibar and Pemba have precipitation levels of about 60 inches (1,520 mm) and 80 inches (2,030 mm), respectively. Precipitation levels are highest in April and May and lowest in November and December. Humidity is high. The average temperature is in the low 80s F (high 20s C) in Zanzibar and the high 70s F (mid-20s C) in Pemba; the annual temperature ranges are small.

• Plant and animal life

Long-term human occupation has resulted in the clearance of most of the forests, which have been replaced with coconuts, cloves, bananas, citrus, and other crops. On the eastern side of the islands, especially on Zanzibar, there is bush (scrub).

Although there is some difference between the animal life of the two islands, it is generally similar to that on the mainland. Animal life common to both islands includes monkeys, civet cats, and mongooses. More than 100 species of birds have been recorded in Zanzibar.

People

Tanzania mainland

• Ethnic groups

According to most reputable surveys, Tanzania’s population includes more than 120 different indigenous African peoples, most of whom are today clustered into larger groupings. Because of the effects of rural-to-urban migration, modernization, and politicization, some of the smallest ethnic groups are gradually disappearing.

As early as 5000 BCE, San-type hunting bands inhabited the country. The Sandawe hunters of northern mainland Tanzania are thought to be their descendants. By 1000 BCE, agriculture and pastoral practices were being introduced through the migration of Cushitic people from Ethiopia. The Iraqw, the Mbugu, the Gorowa, and the Burungi have Cushitic origins. About 500 CE, iron-using Bantu agriculturalists arriving from the west and south started displacing or absorbing the San hunters and gatherers; at roughly the same time, Nilotic pastoralists entered the area from the southern Sudan.

Tanzania: Ethnolinguistic composition

Today the majority of Tanzanians are of Bantu descent; the Sukuma who live in the north of the country, south of Lake Victoria constitute the largest group. Other Bantu peoples include the Nyamwezi, concentrated in the west-central region; the Hehe and the Haya, located in the country’s southern highlands and its northwest corner, respectively; the Chaga of the Kilimanjaro region, who inhabit the mountain’s southern slopes; and the Makonde, who reside in the Mtwara and Ruvuma regions of the southeast. Nilotic peoples represented by the Maasai, the Arusha, the Samburu, and the Baraguyu live in the north-central area of mainland Tanzania. The Zaramo, a highly diluted and urbanized group, constitute another ethnic group of considerable size and influence. The majority of the Zaramo live in the environs of Dar es Salaam and the adjacent coastline. The Zanaki—the ethnic group smallest in number dwell near Musoma in the Lake Victoria region. Julius Nyerere, the country’s founding father and first president (1962–85), came from this group.

There are also Asian and European minorities. During the colonial period, Asian immigration was encouraged, and Asians dominated the up-country produce trade. Coming mostly from Gujarat in India, they form several groups: the Ismāʿīlīs, the Bohras, the Sikhs, the Punjabis, and the Goans. Since independence, however, the Asian population has steadily declined because of emigration. The European population, never large because Tanganyika was not a settler colony, was made up primarily of English, German, and Greek communities. In the postindependence period, a proliferation of different European, North American, and Japanese expatriates connected with foreign-aid projects made Tanzania their temporary residence.

Unlike many African countries, Tanzania does not have one single politically or culturally dominant ethnic group, although those groups that were subject to Christian missionary influence and Western education during the colonial period (notably the Chaga and the Haya) are better represented in the government administration and cash economy.

• Languages

Tanzania has two official languages, Swahili (kiSwahili) and English. Swahili, the national language, is a composite of several Bantu dialects and Arabic that originated along the East African coast and on the island of Zanzibar. Swahili is the lingua franca of the country, and virtually all Tanzanians speak it. Since independence the government and other national institutions have promoted the use of Swahili through literature, local drama, and poetry. Swahili is also used as the medium of instruction in the first seven years of primary education. English is the medium of instruction at higher levels of education and is widely used in government offices.

In addition to Swahili, most African Tanzanians also speak the traditional language of their ethnic group. The main languages spoken by the Asian minorities in Tanzania are Gujarati, Hindi, Punjabi, and Urdu.

• Religion

Roughly one-third of the population is Muslim, the majority of whom are Sunni; the Shīʿite population of Tanzania includes an Ismāʿīlī community under the spiritual leadership of the Aga Khan. An additional one-third of Tanzanians profess Christianity, which in Tanzania includes Roman Catholic, Lutheran, Methodist, and Baptist sects. The remainder of the population is considered to hold traditional beliefs. The division is usually not as clear as official statistics suggest, since many rural Tanzanians adhere to elements of their indigenous religious practice.

• Settlement patterns

The two most important factors influencing the regional pattern of human settlement are precipitation and the incidence of the tsetse fly. The tsetse, which thrives on wild game in miombo woodlands, is the carrier of Trypanosoma, a blood parasite that causes sleeping sickness in cattle and people. Tsetse infestation makes human settlement hazardous in areas of moderate precipitation, so areas of low and unreliable precipitation are more densely populated than would otherwise be the case. The insect does not pose a threat to areas of high precipitation.

Population is concentrated in the highlands of the Mbeya Range, Kilimanjaro, and the Bukoba area west of Lake Victoria, on the cultivation steppe south of Lake Victoria, in the moderately high-precipitation region of Mtwara on the southern coast, and in the urban area of Dar es Salaam—areas all located on the perimeter of the country. The influence of the central rail line is clearly evident in the corridor of moderate population density extending from Dar es Salaam to Lake Victoria. Areas of especially sparse population include the Rukwa region, situated along a portion of Lake Tanganyika in the west, and the two large tsetse-infested areas centred around Tabora north of Rukwa in the west and Lindi and Songea in the south.

Regional variations in agricultural productivity are strongly related to the pressure of population on the land. Shifting cultivation, which involves rotating crops annually and leaving some fields to lie fallow for 20 years or more, was traditionally the means of renewing the fertility of the soil, except in the more fertile and densely populated highland areas. A settlement pattern of widely dispersed isolated farmsteads resulted from this practice. As the rural population expanded, however, fallow periods became shorter, and soil fertility and crop yields consequently suffered. In order to raise productivity, during the 1960s and ’70s the government tried to bring about the use of improved agricultural methods, equipment, and fertilizer through the nucleation of rural settlements. First, the ujamaa (or “familyhood”) policy of the 1960s supported collectivized agriculture in a number of government-sponsored planned settlements. These settlements were overreliant on government finance and gradually dwindled in number. On a much larger scale, the “villagization” program of the 1970s moved millions of people into nucleated villages of 250 households or more, and by 1978 there were more than 7,500 villages, in comparison with only about 800 in 1969. Villagization was aimed not at collectivizing agriculture but at facilitating the distribution of agricultural inputs such as fertilizers and improved seeds as well as making social services more accessible to the rural population.

Almost one-third of the population lives in urban areas, and more than one-tenth of the urban population resides in Dar es Salaam. Bagamoyo and Tabora, old towns connected with the 19th-century Arab slave trade, have stagnated. The fortunes of Tanga, the second largest city during the British colonial period, have been tied to the export of sisal; as that has declined, the growth of the city has slowed. Arusha, Mbeya, and Mwanza have thrived as trading centres remote from Dar es Salaam, and the growth of Morogoro and Moshi reflects their rich agricultural hinterlands.

Tanzania: Urban-rural

• Demographic trends

Tanzania’s population growth rate is lower than the world average and below that of many of the countries of sub-Saharan Africa. More than two-fifths of Tanzanians are under the age of 15. Life expectancy, at about 50 years, is above average for the subcontinent. Beginning in the early 1960s, Tanzania witnessed a gradual decline in infant mortality; in the early 21st century, infant mortality dropped below the average rate for sub-Saharan Africa.

Zanzibar and Pemba

• Ethnic groups

There are several groups of Africans present on the islands. Indigenous Bantu groups, consisting of the Pemba in Pemba and the Hadimu and Tumbatu in Zanzibar, have absorbed the settlers who moved from Persia in the 10th century. These groups and some of the descendants of slaves call themselves Shirazi. There are also small enclaves of Comorians and Somalis. Arab settlements were also established early, and intermarriage with the local people took place. Arab arrivals in the 18th and 19th centuries were from Oman and constituted an elite. The Omani immigrants in the early 20th century tended to be less affluent. Asians form a very small minority.

• Languages

Swahili is the principal language in Zanzibar and Pemba. The classical dialect is Kiunguja. Arabic is also important, because of long-established Islamic tradition, past Arab influence, and the presence of a large Arabic-speaking minority. Among the Asian communities, the chief languages are Gujarati, Kutchi, and Hindustani. English, taught in schools, is widely used.

• Religion

Almost the whole of the Arab and the African peoples of Zanzibar profess the Islamic faith. Traditional African beliefs also exist in conjunction with Islam. Among Muslims, the Sunni sect is adhered to by many of the indigenous people.

• Settlement patterns

The rural settlements—and life in them—changed drastically after the nationalization of land in 1964 and subsequent agricultural reforms. By 1970, large plantations of cloves and coconuts, once almost exclusively the property of fewer than 50 Arab families, had been redistributed. The production of food crops, especially rice, is being encouraged. Fishing villages are still important in the east.

The city of Zanzibar is still primarily a Muslim town, although the distinctive mode of life and culture, reminiscent of an Eastern commercial centre, has almost disappeared since the downfall of the Arab oligarchy in 1964. The hub of civic life is moving from Stone Town with its narrow lanes to a new town with modern buildings and amenities at Ngambo, the former African quarter. Kilimani, Bambi, and Chaani are being developed into new rural towns; a similar change is taking place in Pemba at Mkoani, Chake Chake, and Wete.Adolfo C. Mascarenhas

• Economy

The Tanzanian economy is overwhelmingly agrarian. The country’s preoccupation with agricultural production, which increased in the 1970s and ’80s, is a reflection of the government’s commitment at that time to socialist development and central planning, as outlined in the Arusha Declaration of 1967. The declaration also resulted in the nationalization of a number of industries and public services. In the long term, however, the centrally planned economy contributed to a marked economic decline.

Beginning in 1979 and continuing into the 1980s, the relatively high international oil price, the country’s declining terms of trade, and the sluggishness of the domestic economy brought about rapid inflation and the emergence of an unofficial market (consisting of the smuggling of goods abroad in order to avoid taxes and price controls). Despite attempts to cut imports to the barest minimum, the trade deficit widened to an unprecedented level, and the balance-of-payments problem became so acute that development projects had to be suspended. This economic crisis forced the government to secure a loan from the International Monetary Fund (IMF) in 1986. The loan’s conditions required the elimination of subsidies and price controls as well as some social services and staff positions in state-run enterprises. In the 1990s and 2000s, the government continued to implement measures intended to create a mixed economy and reduce the extent of the untaxable unofficial markets.

• Agriculture, forestry, and fishing

Some two-fifths of the country’s population is engaged in agricultural production (working as independent producers or salaried farm labourers), and agriculture accounts for approximately the same proportion of the country’s gross domestic product. The major food crops are corn (maize), rice, sorghum, millet, bananas, cassava (manioc), sweet potatoes, barley, potatoes, and wheat. Corn and rice are the preferred cereals, whereas cassava and sweet potatoes are used as famine-prevention crops because of their drought-resistant qualities. In some areas food crops are sold as cash crops. Agriculturalists in the Ruvuma and Rukwa regions, for example, have specialized in commercial corn production, and in riverine areas, especially along the Rufiji, rice is sold.

Export cash crops are a source of foreign exchange for the country. Coffee and cotton are by far the most important in this respect, but other exports include cashew nuts, tea, tobacco, and sisal. Once the source of more than nine-tenths of the world’s cloves, Zanzibar now produces only about one-tenth of the international supply.

The villagization program of the mid-1970s was followed by government efforts to distribute improved seed corn and fertilizers through the new village administrations, but timely distribution of such agricultural inputs was largely thwarted by the logistical problems of transporting them to the villages. Nevertheless, increased yields, attributed to the use of chemical fertilizers, have been achieved in corn production in the southern and southwestern regions.

Tanzania’s native forests are primarily composed of hardwoods, but softwood production is increasing. A large pulp and paper mill at Mufindi is supplied by the extensive softwood forest nearby at Sao Hill.

Several lakes, especially Lake Victoria, are important sources of fish. Prawns are commercially fished in the Rufiji River delta, but coastal fishery is primarily of an artisanal nature.

• Resources and power

Diamonds, gold, kaolin, gypsum, tin, and various gemstones, including tanzanite, are mined in Tanzania. Gold is an important resource and the country’s most valuable export. There are large exploitable deposits of coal in the southwest, phosphate deposits in Arusha, and nickel in the Kagera region. Natural gas has been discovered at Songo Songo Island. Several international companies have been involved in onshore and offshore petroleum exploration.

Imported petroleum, hydroelectric power, and coal are the main sources of commercial energy. Firewood and charcoal are the major domestic fuels, contributing to a growing concern about deforestation. Many Tanzanians are unable to access the main power grid. The majority of those connected reside in urban areas, and plans to take electricity to villages are intended to have the added benefit of also slowing deforestation there.

• Manufacturing

Tanzania’s industry is based on the processing of its agricultural goods and on import substitution—that is, the manufacture (often from imported materials and parts) of products that were once purchased from abroad. The principal industries are food processing, textiles, brewing, and cigarette production. Production of cement, clothing, footwear, tires, batteries, and bottles takes place as well. There are a number of steel mills and a large pulp and paper mill. Bicycles are also manufactured.

A strategy to lay the foundation for the rapid growth of such basic industries as steel, chemicals, rubber, and textiles was thwarted by the national economic crisis of the 1980s. The large amounts of imported materials, parts, and capital equipment necessary to implement such a policy could not be paid for, owing to the country’s lack of foreign exchange. Standby credit facilities from the IMF provided the capital investment needed to initiate a rehabilitation of industry. Difficulty in obtaining adequate power supply (a large proportion of the country is not linked to the main electricity grid) remained an obstacle to the development of manufacturing capabilities in the early 21st century.

• Finance

All private banks were nationalized between 1967 and 1992, but since then private banks (including branches of foreign-owned banks) have been allowed to open. The state-run Bank of Tanzania operates as the central bank; it manages the country’s finances and issues its currency, the Tanzanian shilling. A stock exchange was incorporated in Dar es Salaam in 1996; trading began two years later.

• Trade

Tanzania’s principal exports are gold, coffee, cashew nuts, and cotton. Of these, gold which provided more than two-thirds of the country’s export earnings in the early 2000s is by far the most lucrative. Other exports include agricultural products and materials, gemstones, and textiles. Countries that receive Tanzania’s exports include Switzerland, India, South Africa, and China. Tanzania’s primary imports consist of machinery, transport equipment, and petroleum and chemical products; the majority of the country’s imported goods are received from countries such as India, South Africa, the United Arab Emirates, China, and Switzerland.

Tanzania: Major import sources

• Services

Tanzania’s rapidly expanding tourism sector continues to be a source of great economic promise. Mount Kilimanjaro, the highest peak in Africa, serves as a major tourist attraction, as does the country’s network of national parks, reserves, and conservation areas, which together span some one-fourth of the country. Tanzania’s beaches and coral reefs are also attractive to tourists, and the government has increasingly marketed its coastline and encouraged diving and snorkeling there. Neighbouring Kenya supplies the vast majority of visitors to Tanzania, many of whom visit the country on short day trips. By the early 2000s, tourism accounted for almost one-fifth of the gross domestic product, while the services sector on the whole accounted for almost two-fifths.

• Labour and taxation

Some four-fifths of the Tanzanian labour force is employed in the agricultural sector. Of that group, less than one-tenth belongs to unions. Labour laws in mainland Tanzania and in Zanzibar are particular to each area, and workers in Zanzibar are not allowed to join mainland unions. Although workers are permitted to form labour unions without authorization, many private-sector employers have adopted illegal policies that discourage the joining or formation of unions. The Trade Union Congress of Tanzania is the country’s only labour federation.

The value-added tax (VAT), the income tax, the excise tax, and imports duties contribute to the national revenue. The government is deprived of substantial tax income by informal-sector economic activity, which is not taxed; in addition, tax collection itself is not considered adequately efficient.

• Transportation

Transport in Tanzania spans a wide spectrum, from the motorized means made possible by roads, seaports, airfields, and railways to the traditional carrying of loads by animals and people.

The road network extends to all parts of the country, but it is densest along the coast and southeast of Lake Victoria. Only a fraction of the roadways in Tanzania are paved. The Tanzam Highway, opened in the early 1970s between Dar es Salaam and Zambia, has significantly reduced the isolation of southern Tanzania. Another highway intersects it at Makambako and proceeds southward through the southern highlands to Songea. Government efforts have focused on rehabilitating the trunk road system, which deteriorated with a decline in the importation of maintenance materials during the economic crisis.

Dar es Salaam port, with its deepwater berths, handles the majority of shipping traffic at Tanzanian ports. The remainder goes primarily to Mtwara, Tanga, and the port of the city of Zanzibar. The Tanzania Coastal Shipping Line offers transport services along the coast; a passenger ferry operates between Dar es Salaam and Zanzibar. In addition to these, there are also inland ports situated on Lake Victoria by which traffic with the neighbouring countries of Uganda and Kenya is conducted; inland ports on Lake Nyasa and Lake Tanganyika serve to connect Tanzania with points in Malawi, Mozambique, and the Democratic Republic of the Congo.

Several airlines, including the national carrier, Air Tanzania, provide domestic and international service. There are numerous airports throughout the country, including international airports at Dar es Salaam, Kilimanjaro, Mwanza, and Zanzibar; most scheduled international flights land in Dar es Salaam.

The railway system dates back to the pre-World War I German-built Central Railway Line, which bisects the country between Dar es Salaam and Kigoma, and the Tanga-to-Moshi railway. There is also a branch between these two lines, and another line connects Mwanza with Tabora on the Central Line. The Tanzania-Zambia Railway Authority (TAZARA) rail line, running between Dar es Salaam and Kapiri-Mposhi on the Zambian border, was built with Chinese aid in the early 1970s. It provided the main outlet to the sea for Zambia’s copper exports prior to the political changes in South Africa in the 1990s that opened southern transport routes for Tanzania’s landlocked neighbour.

Government And Society

• Constitutional framework

The Interim Constitution of 1965 established the United Republic of Tanzania through the merger of Tanganyika and Zanzibar, until then separate and independent countries. A permanent constitution for the United Republic was approved in 1977 and amended in 1984 to include a bill of rights.

Zanzibar has a separate constitution, approved in 1979 and amended in 1985. The executive branch is composed of a president, elected by popular vote to a maximum of two five-year terms, and a cabinet called the Supreme Revolutionary Council. Zanzibar’s parliament, the House of Representatives, is made up of elected and appointed members. These political bodies deal with matters internal to Zanzibar. Since the union with Tanganyika, some segments of Zanzibari society have occasionally demanded greater autonomy from the mainland.

The president of the United Republic is the head of state and commander in chief of the armed forces. The cabinet of ministers is advisory to the president. Prior to 1995 it included two vice presidents: the prime minister, who is appointed by the president and acts as the leader of the cabinet, and the president of Zanzibar. Since then an amendment to the constitution, which was approved in 1994 and took effect after the 1995 general election, has rescinded the stipulation that called for the president of Zanzibar to serve as a vice president.

According to the 1984 constitutional amendments, most members of the unicameral National Assembly are directly elected. Many seats also are allocated to ex-officio, nominated, and indirectly elected members—including those seats reserved for women, representatives of mass organizations, and the president’s nominees. The National Assembly has a term of five years but can be dissolved by the president before this term expires.

• Local government

For administrative purposes, mainland Tanzania is divided into regions. Each region is administered by a commissioner who is appointed by the central government. At district, division, and ward levels, there are popularly elected councils with appointed executive officers.Deborah Fahy BrycesonThe Editors of Encyclopaedia Britannica

• Justice

Tanzania’s judiciary is appointed by the president in consultation with the chief justice. A network of primary and district courts has been established throughout the country; right of appeal for the district courts is to the high court. English, Islamic, and customary laws have been absorbed into the legal system. In Zanzibar the highest judicial authority is the Supreme Council. Muslim courts deal with marriage, divorce, and inheritance.

• Political process

By law Tanzania was a one-party state until 1992, when the constitution was amended to establish a multiparty political process. In 1977 the Tanganyika African National Union (TANU), which had led the colony to independence, and the Afro-Shirazi Party (ASP) of Zanzibar, which had taken power after a coup in 1964, merged to form the Revolutionary Party (Chama cha Mapinduzi; CCM), and a new constitution was adopted the same year. Prior to the 1992 amendment, the CCM dominated all aspects of political life, and there was no clear separation of party and government personnel at regional and district levels. In 1995 Tanzania conducted its first multiparty general elections in more than 30 years for the office of president and for members of the parliament. Although more than a dozen opposition political movements were officially registered and participated in the elections, the CCM continued to control the Union government; its involvement in local government and other local affairs, however, began to wane, particularly its administration of the 10-cell neighbourhood watch program (with each cell varying in size from single-family homes to large apartment buildings). Individuals are eligible to vote at 18 years of age, and suffrage is universal.

The attainment of independence brought with it significant changes of attitudes toward women. TANU and later the Tanzanian government—was concerned with human welfare and an improved status for all age groups and both sexes, as expressed in its policies guaranteeing equal rights and educational opportunities. Women were encouraged to participate in political activities, and as a result, several cabinet members are women, while others hold senior positions in government and the private sector. Women who played prominent roles in early nationalist activities include Bibi Titi Mohamed and Lucy Lameck.Frank Matthew Chiteji

National and local governments support a network of village dispensaries and rural health centres; hospitals are located in the urban areas. Private doctors and religious organizations provide medical facilities as well.

The emphasis of national health policy has been on preventive medicine, including better nutrition, maternal and child health, environmental sanitation, and prevention and control of communicable diseases—especially HIV/AIDS, which in Tanzania was first reported in 1983 and became a serious problem in the 1990s. Although HIV/AIDS is more prevalent in major cities and towns, it has spread to villages and rural areas, especially those close to cities or on connecting roads and in border towns. In response, the Tanzanian government has instituted aggressive health campaigns to educate the public, distribute or encourage the use of condoms, safeguard blood supplies, and discourage risky sexual activity; these factors have likely contributed to the decline of the HIV prevalence rate in the 2000s.

Apart from HIV/AIDS, the main communicable diseases are poliomyelitis, leprosy, tuberculosis, dysentery, and enteric fevers. Other health concerns include environmental diseases such as malaria, sleeping sickness, schistosomiasis, and onchocerciasis (river blindness). Inadequate nutrition, particularly of children, is a major concern. Improvements in health and reduction of mortality rates have resulted from the provision of medical care to the rural population and from an inoculation program for children.Frank Matthew Chiteji

• Education

The government-supported education system has three levels: primary (seven years), secondary (four to six years), and university, as well as vocational training schools. During the mid-1970s, universal primary education was made mandatory, which resulted in a vast increase in primary-school children. Popular pressure for the expansion of secondary schools has outstripped the availability of government finance. As a result, private secondary schools sponsored by religious institutions and, most notably, by parents themselves have expanded in number. Universities in Tanzania include the University of Dar es Salaam (1961), formerly part of the University of East Africa, Sokoine University of Agriculture (1984), and Zanzibar University (1998). Extensive adult education has focused on eradicating illiteracy, and, as a result, more than two-thirds of the adult population is literate—above the average for African countries but below the world average.

Cultural Life

• Cultural milieu

Olduvai Gorge, in the Great Rift Valley, is the site of the discovery of some of the earliest known remains of human ancestry, dating back 1.75 million years. The ancient in-migration of Cushitic, Nilotic, and Bantu peoples, displacing the native San-type population, resulted in a complex agglomeration of communities practicing complementary forms of pastoral and agricultural livelihoods. Portuguese, Arab, Indian, German, and British traders and colonists later added to the mosaic. Today Tanzania’s multiethnic and multiracial population practices a variety of traditions and customs that form a rich cultural heritage.

A number of unique features located throughout the country have been recognized as UNESCO World Heritage sites for their cultural and natural value; among these are the rock-painting sites at Kondoa, the ruins of the ancient ports of Kilwa Kisiwani and Songo Mnara, and Stone Town in Zanzibar.

• Daily life and social customs

The role of kin is central to Tanzanian social and recreational life. Visiting kin on joyous and sorrowful family occasions is given high priority despite the inconvenience caused by a relatively undeveloped transport system. Educated members of the extended family are frequently held responsible for the education and welfare of younger siblings.

• The arts

Oral storytelling traditions and tribal dancing are an important part of the cultural life of the rural population. The University of Dar es Salaam has an active theatre arts group. Makonde carvers from southern Tanzania are renowned for their abstract ebony carvings, and Zanzibar is famous for its elaborately carved doors and Arab chests. Basket weaving, pottery, and musical instrument making are prevalent in many rural areas.

Throughout the 20th century, traditional musical themes and sounds were coupled with a variety of influences to produce popular music. In the 1930s music exhibiting Cuban elements was popular; in the 1960s Congolese music, with its distinctive guitar sound and blend of Cuban and African rhythms, was favoured. In the early 21st century rap and reggae emerged as choice musical genres, and mchiriku, a techno-style sound influenced by traditional rhythms, also became popular.

• Cultural institutions

A number of Tanzania’s significant cultural institutions are concentrated in Dar es Salaam. Among these are the National Museum, which houses items excavated from the Olduvai Gorge—such as the famed Zinjanthropus boisei skull discovered by Mary Leakey in 1959—and other archaeological sites. Branch museums include the Arusha Natural History Museum, the Arusha Declaration Museum, which contains exhibitions on Tanzania’s social and political history, and the Village Museum in Dar es Salaam, which displays traditional crafts. The national archives are also located in Dar es Salaam, as is the library affiliated with the university there. The Zanzibar Government Museum and Zanzibar’s national archives are located on Zanzibar Island.

• Sports and recreation

Tanzania has a highly developed system of sports education, and schools of all levels emphasize physical fitness in their curricula. Tanzanians enjoy football (soccer) as both spectators and players. The country’s Mainland League is closely followed, and cities such as Dar es Salaam and Dodoma nurse friendly rivalries on and off the field. Basketball is also popular.

Tanzania organized a national Olympic committee in 1968 and was recognized by the International Olympic Committee that year. Athletes representing Tanganyika participated in the 1964 Tokyo Games, and Tanzania made its debut at the 1968 Games in Mexico City. Although Tanzania joined the African boycott of the 1976 Montreal Games, it has consistently participated in the Summer Olympiad since that time, winning silver medals for the steeplechase and the 5,000-metre race in 1980. The marathon is the event that has brought the country the most honour, however. Long-distance runners Zebedayo Bayo and Juma Ikangaa are national favourites.

• Media and publishing

Radio is the primary medium through which the rural population receives national and international news. The medium also has been extensively used by the government for the promotion of adult literacy, better nutrition, and ecological conservation. There are a number of radio stations broadcasting in Tanzania, including Radio Tanzania and Radio Tanzania Zanzibar, which are state-owned; Radio One, which is privately owned; and Radio Tumaini, which is owned by the Roman Catholic Church. Most television stations are privately owned. There are television stations based both on the mainland and in Zanzibar. Tanzania has government-owned and independent daily newspapers. Among those published in Swahili are Uhuru and Majira; in English, The Democrat and Daily News.

History

Tanganyika

• Early exploration

Most of the known history of Tanganyika before the 19th century concerns the coastal area, although the interior has a number of important prehistoric sites. The most significant of these is the Olduvai Gorge, situated in the northwestern corner of Tanzania near the Ngorongoro crater. In 1959, following years of excavations in the gorge with her husband, Louis Leakey, Mary Leakey discovered the near-perfect skull of the “Eastern Man” (Zinjanthropus boisei; now regarded as Paranthropus boisei, a type of australopith), who inhabited the area between 2.3 and 1.2 million years ago. Available evidence from other archaeological sites and historical records attests to the existence of numerous major waves of in-migration onto the Tanzanian littoral over the millennia. The earliest of these likely included traders from such locales as Greece, Rome, Phoenicia, Arabia, Persia, and India, possibly beginning as early as the 5th century BCE and continuing into the next millennium.

The trading contacts between Arabia and the East African coast resulted in the establishment of numerous Asian and Arab trade settlements along the coast and in the interior of what is now the Tanzania mainland. The coastal trading centres were mainly Arab-controlled, and relations between the Arabs and their African neighbours appear to have been fairly friendly. After the arrival of the Portuguese in the late 15th century, the position of the Arabs was gradually undermined, but the Portuguese made little attempt to penetrate into the interior. They lost their foothold north of the Ruvuma River early in the 18th century as a result of an alliance between the coastal Arabs and the ruler of Muscat on the Arabian Peninsula. This alliance remained extremely tenuous, however, until French interest in the slave trade from the Tanganyikan coastal town of Kilwa revived the trade in 1776. This attention by the French aroused the sultan of Muscat’s interest in the economic possibilities of the East African coast, and a new Omani governor was appointed at Kilwa. For some time most of the slaves came from the Kilwa hinterland, and until the 19th century any contact between the coast and the interior was due mainly to African caravans from the interior.

In their constant search for slaves, Arab traders began to penetrate farther into the interior, particularly in the southeast toward Lake Nyasa. Farther north two merchants from India followed the tribal trade routes to reach the country of the Nyamwezi about 1825. Along this route ivory appears to have been as great an attraction as slaves, and Saʿīd ibn Sulṭān himself, after the transfer of his capital from Muscat to Zanzibar, gave every encouragement to the Arabs to pursue these trading possibilities. From the Nyamwezi country the Arabs pressed on to Lake Tanganyika in the early 1840s. Tabora (or Kazé, as it was then called) and Ujiji, on Lake Tanganyika, became important trading centres, and a number of Arabs made their homes there. They did not annex these territories but occasionally ejected hostile chieftains. Mirambo, an African chief who built for himself a temporary empire to the west of Tabora in the 1860s and ’70s, effectively blocked the Arab trade routes when they refused to pay him tribute. His empire was purely a personal one, however, and collapsed on his death in 1884.

The first Europeans to show an interest in Tanganyika in the 19th century were missionaries of the Church Missionary Society, Johann Ludwig Krapf and Johannes Rebmann, who in the late 1840s reached Kilimanjaro. It was a fellow missionary, Jakob Erhardt, whose famous “slug” map (showing, on Arab information, a vast shapeless inland lake) helped stimulate the interest of the British explorers Richard Burton and John Hanning Speke. They traveled from Bagamoyo to Lake Tanganyika in 1857–58, and Speke also saw Lake Victoria. This expedition was followed by Speke’s second journey, in 1860, in the company of J.A. Grant, to justify the former’s claim that the Nile River rose in Lake Victoria. These primarily geographic explorations were followed by the activities of David Livingstone, who in 1866 set out on his last journey for Lake Nyasa. Livingstone’s object was to expose the horrors of the slave trade and, by opening up legitimate trade with the interior, to destroy the slave trade at its roots. Livingstone’s journey led to the later expeditions of H.M. Stanley and V.L. Cameron. Spurred on by Livingstone’s work and example, a number of missionary societies began to take an interest in East Africa after 1860.

• German East Africa

It was left to Germany, with its newly awakened interest in colonial expansion, to open up the country to European influences. The first agent of German imperialism was Carl Peters, who, with Count Joachim von Pfeil and Karl Juhlke, evaded the sultan of Zanzibar late in 1884 to land on the mainland and made a number of “contracts” in the Usambara area by which several chiefs were said to have surrendered their territory to him. Peters’s activities were confirmed by Otto von Bismarck, chancellor of the German Empire. By the Anglo-German Agreement of 1886, the sultan of Zanzibar’s vaguely substantiated claims to dominion on the mainland were limited to a 10-mile- (16-km-) wide coastal strip, and Britain and Germany divided the hinterland between them as spheres of influence, the region to the south becoming known as German East Africa. Following the example of the British to the north, the Germans obtained a lease on the coastal strip from the sultan in 1888, but their tactlessness and fear of commercial competition led to a Muslim uprising in August 1888. The rebellion was put down only after the intervention of the imperial German government and with the assistance of the British navy

Recognizing the administrative inability of the German East Africa Company, which had theretofore ruled the country, the German government in 1891 declared a protectorate over its sphere of influence and over the coastal strip, where the company had bought out the sultan’s rights. Germany was eager to exploit the resources of its new dependency, but lack of communications at first restricted development to the coastal area. The German agronomist Richard Hindorff’s introduction of sisal from Florida in 1892 marked the beginning of the territory’s most valuable industry, which was encouraged by the development of a railway from the new capital of Dar es Salaam to Lake Tanganyika. In 1896 work began on the construction of a railway running northeastward from Tanga to Moshi, which it reached in 1912. This successfully encouraged the pioneer coffee-growing activities on the slopes of Kilimanjaro. Wild rubber tapped by Africans, together with plantation-grown rubber, contributed to the economic development of the colony. The government also supplied good-quality cottonseed free to African growers and sold it cheaply to European planters. The administration tried to rectify the lack of clerks and minor craftsmen by encouraging the development of schools, an activity in which various missionary societies were already engaged.

The enforcement of German overlordship was strongly resisted, but control was established by the beginning of the 20th century. Almost at once came a reaction to German methods of administration, the outbreak of the Maji Maji uprising in 1905. Although there was little organization behind it, the uprising spread over a considerable portion of southeastern Tanganyika and was not finally suppressed until 1907. It led to a reappraisal of German policy in East Africa. The imperial government had attempted to protect African land rights in 1895 but had failed in its objective in the Kilimanjaro area. Similarly, liberal labour legislation had not been properly implemented. The German government set up a separate Colonial Department in 1907, and more money was invested in East Africa. A more liberal form of administration rapidly replaced the previous semimilitary system.

World War I put an end to all German experiments. Blockaded by the British navy, the country could neither export produce nor get help from Germany. The British advance into German territory continued steadily from 1916 until the whole country was eventually occupied. The effects of the war upon Germany’s achievements in East Africa were disastrous; the administration and economy were completely disrupted. In these circumstances the Africans reverted to their old social systems and their old form of subsistence farming. Under the Treaty of Versailles (signed June 1919; enacted January 1920), Britain received a League of Nations mandate to administer the territory except for Ruanda-Urundi, which came under Belgian administration, and the Kionga triangle, which went to Portugal (see Quionga).

• Tanganyika Territory

Sir Horace Byatt, administrator of the captured territory and, from 1920 to 1924, first British governor and commander in chief of Tanganyika Territory (as it was then renamed), enforced a period of recuperation before new development plans were set in motion. A Land Ordinance (1923) ensured that African land rights were secure. Sir Donald Cameron, governor from 1925 to 1931, infused a new vigour into the country. He reorganized the system of native administration by the Native Authority Ordinance (1926) and the Native Courts Ordinance (1929). His object was to build up local government on the basis of traditional authorities, an aim that he pursued with doctrinaire enthusiasm and success. He attempted to silence the criticisms by Europeans that had been leveled against his predecessor by urging the creation of a Legislative Council in 1926 with a reasonable number of nonofficial members, both European and Asian. In his campaign to develop the country’s economy, Cameron won a victory over opposition from Kenya by gaining the British government’s approval for an extension of the Central Railway Line from Tabora to Mwanza (1928). His attitude toward European settlers was determined by their potential contribution to the country’s economy. He therefore was surprised by the British government’s reluctance to permit settlement in Tanganyika. The economic depression after 1929 resulted in the curtailment of many of Cameron’s development proposals. In the 1930s, there were persistent fears that Tanganyika might be handed back to Germany in response to demands by Adolf Hitler then chancellor of Germany—for overseas possessions.

At the outbreak of World War II, Tanganyika’s main task was to make itself as independent as possible of imported goods. Inevitably the retrenchment evident in the 1930s became still more severe, and, while prices for primary products soared, the value of money depreciated proportionately. Tanganyika’s main objective after the war was to ensure that its program for economic recovery and development went ahead. The continuing demand for primary produce strengthened the country’s financial position. The chief item in the development program was a plan to devote 3 million acres (1.2 million hectares) of land to the production of peanuts (the Groundnuts Scheme). The plan, which was to be financed by the British government, was to cost £25 million, and, in addition, a further £4.5 million would be required for the construction of a railway in southern Tanganyika. It failed because of the lack of adequate preliminary investigations and was subsequently carried out on a greatly reduced scale.

Constitutionally, the most important immediate postwar development was the British government’s decision to place Tanganyika under United Nations trusteeship (1947). Under the terms of the trusteeship agreement, Britain was called upon to develop the political life of the territory, which, however, only gradually began to take shape in the 1950s. In 1953 Julius Nyerere was elected president of the Tanganyika African Association (TAA), an organization made up mainly of African civil servants, which had been formed in Dar es Salaam in 1929. In early 1954 Nyerere and his associates transformed the TAA from a social organization to a political one, and later the same year the TAA became the Tanganyika African National Union (TANU), with the stated aims of self-government and independence.

The first two African members had been nominated to the Legislative Council in December 1945. This number was subsequently increased to four, with three Asian nonofficial members and four Europeans. An official majority was retained. In an important advance in 1955, the three groups were given parity of representation on the unofficial side of the council with 10 nominated members each, and for a time it seemed as if this basis would persist. The first elections to the unofficial side of the council (in 1958 and 1959), however, enabled TANU to show its strength, for even among the European and Asian candidates, only those supported by TANU were elected.

• Independence

A constitutional committee in 1959 unanimously recommended that after the elections in 1960 a large majority of the members of both sides of the council be Africans and that elected members form the basis of the government. In the 1960 Legislative Council elections, TANU and its allies were again overwhelmingly victorious, and when Tanganyika became independent on December 9, 1961, Nyerere became its first prime minister. The next month, however, he resigned from this position in order to devote his time to writing and to synthesizing his views of government and of African unity; he was succeeded by Rashidi Kawawa. One of Nyerere’s more important works was a paper called “Ujamaa—the Basis for African Socialism,” which later served as the philosophical basis for the Arusha Declaration of 1967.

On December 9, 1962, Tanganyika adopted a republican constitution, and Nyerere became executive president of the country. The next month, he announced that in the interest of national unity and economic development, TANU had decided that Tanganyika would now be a one-party state. Nyerere’s administration was challenged in 1964; an army mutiny was suppressed in January only after the president reluctantly sought the assistance of British marines.

Although TANU was the only legal party, voters in each constituency were often offered a choice between more than one TANU candidate in parliamentary elections. That this arrangement amounted to something more than lip service to the idea of democracy was demonstrated in 1965 and in subsequent elections when, although Nyerere was reelected again and again as the sole candidate for president, a considerable number of legislators, including cabinet ministers, lost their seats.

• Zanzibar

The history of Zanzibar has been to a large extent shaped by the monsoons (prevailing trade winds) and by the island’s proximity to the African continent. The regular annual recurrence of the monsoons has made possible Zanzibar’s close connection with India and the countries bordering the Red Sea and the Persian Gulf. Its proximity to the continent has made it a suitable jumping-off point for trading and exploring ventures not only along the coast but also into the interior.

• Portuguese and Omani domination

Though the first references to Zanzibar occur only after the rise of Islam, there appears to be little doubt that its close connection with southern Arabia and the countries bordering the Persian Gulf began before the Common Era. At the beginning of the 13th century, the Arab geographer Yāqūt recorded that the people of Langujah (namely, Unguja, the Swahili name for Zanzibar) had taken refuge from their enemies on the nearby island of Tumbatu, the inhabitants of which were Muslim.

In 1498 Vasco da Gama visited Malindi, and in 1503 Zanzibar Island was attacked and made tributary by the Portuguese. It appears to have remained in that condition for about a quarter of a century. Thereafter the relations between the rulers of Zanzibar and the Portuguese seem to have been those of allies, the people of Zanzibar more than once cooperating with the Portuguese in attacks upon Mombasa. In 1571 the “king” of Zanzibar, in gratitude for Portuguese assistance in expelling certain African invaders, donated the island to his allies, but the donation was never implemented. A Portuguese trading factory and an Augustinian mission were established on the site of the modern city of Zanzibar, and a few Portuguese appear also to have settled as farmers in different parts of the island. The first English ship to visit Zanzibar (1591–92) was the Edward Bonaventure, captained by Sir James Lancaster.

When the Arabs captured Mombasa in 1698, all these settlements were abandoned, and (except for a brief Portuguese reoccupation in 1728) Zanzibar and Pemba came under the domination of the Arab rulers of Oman. For more than a century those rulers left the government of Zanzibar to local hakims (governors). The first sultan to take up residence in Zanzibar was Sayyid Saʿīd ibn Sulṭān, who after several short visits settled there soon after 1830 and subsequently greatly extended his influence along the East African coast. On Saʿīd’s death in 1856, his son Majīd succeeded to his African dominions, while another son, Thuwayn, succeeded to Oman.

As a result of an award made in 1860 by Lord Canning, governor general of India, the former African dominions of Saʿīd were declared to be independent of Oman. Majīd died in 1870 and was succeeded by his brother Barghash. Toward the end of the latter’s reign, his claims to dominion on the mainland were restricted by Britain, France, and Germany to a 10-mile- (16-km-) wide coastal strip, the administration of which was subsequently shared by Germany and Britain. Barghash died in 1888. Both he and Majīd had acted largely under the influence of Sir John Kirk, who was British consular representative at Zanzibar from 1866 to 1887. It was by Kirk’s efforts that Barghash consented in 1873 to a treaty for the suppression of the slave trade.

• British protectorate

In 1890 what was left of the sultanate was proclaimed a British protectorate, and in 1891 a constitutional government was instituted under British auspices, with Sir Lloyd Mathews as first minister. On August 25, 1896, on the death of the ruling sultan, Ḥamad ibn Thuwayn, the royal palace at Zanzibar was seized by Khālid ibn Barghash, who proclaimed himself sultan. The British government disapproved, and, as he refused to step down, British warships bombarded the palace on August 27, 1896. The British were victorious in the battle, known as the Anglo-Zanzibar War, which lasted less than an hour and is considered to be the shortest war in recorded history. During the fighting, Khālid escaped and took refuge at the German consulate, whence he was conveyed to German East Africa. After the battle, Ḥamud ibn Moḥammed, favoured by the British, was installed as sultan. In 1897 the legal status of slavery was finally abolished. In 1913 the control of the protectorate passed from the Foreign Office to the Colonial Office, when the posts of consul general and first minister were merged into that of British resident. At the same time, a Protectorate Council was constituted as an advisory body. In 1926 the advisory council was replaced by nominated executive and legislative councils.

Khalīfa ibn Harūb became sultan in 1911. He was the leading Muslim prince in East Africa, and his moderating influence did much to steady Muslim opinion in that part of Africa at times of political crisis, especially during the two World Wars. He died on October 9, 1960, and was succeeded by his eldest son, Sir Abdullah ibn Khalīfa.

In November 1960 the British Parliament approved a new constitution for Zanzibar. The first elections to the Legislative Council then established were held in January 1961 and ended in a deadlock. Further elections, held in June, were marked by serious rioting and heavy casualties. Ten seats were won by the Afro-Shirazi Party (ASP), representing mainly the African population; 10 by the Zanzibar Nationalist Party (ZNP), representing mainly the Zanzibari Arabs; and 3 by the Zanzibar and Pemba People’s Party (ZPPP), an offshoot of the ZNP. The ZNP and the ZPPP combined to form a government with Mohammed Shamte Hamadi as chief minister.

Because of failure to agree on franchise qualifications, the number of elected seats in the legislature, and the timing of the elections, a constitutional conference held in London in 1962 was unable to fix a date for the introduction of internal self-government or for independence. An independent commission, however, subsequently delimited new constituencies and recommended an increase in the numbers of the Legislative Council, which the council accepted, also agreeing to the introduction of universal adult suffrage. Internal self-government was established in June 1963, and elections held the following month resulted in a victory for the ZNP-ZPPP coalition, which won 18 seats, the ASP winning the remaining 13. Final arrangements for independence were made at a conference in London in September. In October it was agreed that the Kenya coastal strip—a territory that extended 10 miles (16 km) inland along the Kenya coast from the Tanganyika frontier to Kipini and that had long been administered by Kenya although nominally under the sovereignty of Zanzibar—would become an integral part of Kenya on that country’s attainment of independence.

• Independence

On December 10, 1963, Zanzibar achieved independence as a member of the Commonwealth. In January 1964 the Zanzibar government was overthrown by an internal revolution, Sayyid Jamshid ibn Abdullah (who had succeeded to the sultanate in July 1963 on his father’s death) was deposed, and a republic was proclaimed.

Although the revolution was carried out by only about 600 armed men under the leadership of the communist-trained “field marshal” John Okello, it won considerable support from the African population. Thousands of Arabs were massacred in riots, and thousands more fled the island. Sheikh Abeid Amani Karume, leader of the ASP, was installed as president of the People’s Republic of Zanzibar and Pemba. Sheikh Abdulla Kassim Hanga was appointed prime minister, and Abdul Raḥman Mohammed (“Babu”), leader of the new left-wing Umma (The Masses) Party (formed by defectors from the ZNP), became minister for defense and external affairs. Pending the establishment of a new constitution, the cabinet and all government departments were placed under the control of a Revolutionary Council of 30 members, which was also vested with temporary legislative powers. Zanzibar was proclaimed a one-party state. Measures taken by the new government included the nationalization of all land, with further powers to confiscate any immovable property without compensation except in cases of undue hardship.

• The United Republic

Zanzibar and the mainland have had a close relationship that dates back to several centuries before the Common Era. Although both were administered separately during colonial rule, Africans from the mainland traveled to Zanzibar for employment, and many who did so settled in the islands permanently. At times during the struggles for national independence, TANU in Tanganyika and the ASP in Zanzibar worked together. The decision of the two countries to amalgamate was a natural outcome of many years of close relationship between the people of Zanzibar and the mainland.

On April 26, 1964, the two countries merged to form the United Republic of Tanganyika and Zanzibar, with Nyerere as president and Karume as first vice president. The nascent country was renamed the United Republic of Tanzania in October 1964. Despite unification, for years Zanzibar continued to pursue its own policies, paying little attention to mainland practices.

• Tanzania under Nyerere

Nyerere’s chief external task was to convince the international community, particularly the Western powers, that Tanzania’s foreign policy was to be one of nonalignment; but the overt involvement of the Eastern bloc in Zanzibar, as well as Nyerere’s own insistence that, to rectify the imbalance created in the colonial era, Tanzania had to turn more to the East for aid, did little to make the task easier. The high moral tone taken by the president over Britain’s role in Rhodesia and over the supply of British arms to South Africa also strained the bonds of friendship between the two countries, with Tanzania severing diplomatic relations with Britain from 1965 to 1968. The consequent loss of aid from Britain was more than compensated for by help from Eastern countries, notably from China, whose aid culminated in 1970 in the offer of an interest-free Chinese loan to finance the construction of a railway line linking Dar es Salaam with Zambia.

Julius Nyerere, 1981.Hanos/Liaison Agency

Though Nyerere fully appreciated the generous assistance his country was receiving, he was eager to impress upon his countrymen the need for maximum self-reliance. Political freedom, he insisted, was useless if the country was to be enslaved by foreign investors. His views were formulated in the Arusha Declaration of February 5, 1967, which put forth the policy of ujamaa (familyhood) and called for socialism and self-reliance. The resources of the country, Nyerere said, were owned by the whole people and were held in trust for their descendants. The leaders had to set an example by rejecting the perquisites of a capitalist system and should draw only one salary. Banks had to be nationalized, though compensation would be given to shareholders; the same would apply to the more important commercial companies. Agriculture, however, was the key to development, and only greater productivity could hold at bay the spectre of poverty. To give a fillip to his argument, people were to be moved into cooperative villages where they could work together for their mutual benefit.

Nyerere’s exhortations did not arouse the enthusiasm for which he had hoped. Individuals resisted his plans for collectivization, and not even the majority of his supporters wholeheartedly adopted his moral stand. The cooperative village scheme failed, bringing additional pressure to bear upon an already desperately weak economy. The sisal industry, one of those nationalized, was badly run down by the mid-1970s because of inefficient management.

Nyerere’s criticisms were not reserved for his own people—or yet for the wealthy countries of the world. In 1968 he challenged the rules of the Organization of African Unity (OAU) by recognizing the secession of Biafra from Nigeria, and in 1975 he attacked the OAU for planning to hold its summit meeting in Uganda, where Pres. Idi Amin was acting with extreme cruelty. Deteriorating relations with both Uganda and Kenya contributed to the collapse of the East African Community in 1977, which had been established 10 years earlier to foster economic development between the three countries.

Tense relations between Tanzania and Uganda in the early 1970s—caused primarily by Nyerere’s continued support of Milton Obote, the former Ugandan president deposed by Amin in 1971—led to occasional border clashes between the two countries. Despite an agreement to cease their hostilities, a new round of conflict was initiated in 1978 when Amin’s forces entered northwestern Tanzania and occupied territory north of the Kagera River; Tanzanian forces counterattacked and regained the region. The clashes continued in the months that followed, and in April 1979, Tanzanian-led forces proceeded to capture the Ugandan capital of Kampala; Amin’s rule ended when he fled the country just before the city was captured. The retention of Tanzanian troops in Uganda for several years after Amin’s overthrow also contributed to strained relations with some of Uganda’s leaders as well as arousing suspicions in Kenya. Elsewhere in Africa, however, Nyerere was able to play an authoritative role, notably in the negotiations leading to the independence of Zimbabwe and in the formation of an organization of African states to try to resist economic domination by South Africa.Kenneth Ingham

Events in Zanzibar caused continuing concern for the mainland leadership. The arbitrary arrest and punishment of anyone believed to oppose the state gave rise to regret that the constitution of the joint republic prevented the mainland authorities from intervening in the island’s affairs where questions of law and justice were involved. The failure to hold elections in Zanzibar also contrasted unfavourably with developments on the mainland. In April 1972 Karume was assassinated by members of the military. His successor, Aboud Jumbe, had been a leading member of Karume’s government, and, while his policies did not differ markedly from those of Karume, they appeared to be moving gradually closer into line with mainland practices. The amalgamation of TANU and the ASP under the title of Revolutionary Party (Chama cha Mapinduzi; CCM) early in 1977 was a hopeful sign but was followed by demands for greater autonomy for Zanzibar. This trend was checked for a short while when Ali Hassan Mwinyi succeeded Jumbe in 1984 and became president of the joint republic after Nyerere resigned in November 1985.

• Political and economic change

Mwinyi inherited an economy suffering from the country’s lack of resources, the fall in world prices for Tanzanian produce, the rise in petroleum prices, and inefficient management. An acute shortage of food added still further to his problems. Though he promised to follow Nyerere’s policy of self-reliance, Mwinyi soon concluded that his predecessor’s resistance to foreign aid could no longer be sustained. In accepting an offer of assistance from the International Monetary Fund (IMF) in 1986, Mwinyi adopted some structural reforms and furthered the devaluation of the currency begun in 1984 by Nyerere, who also had denationalized the state-run sector of the sisal industry in 1985. Moreover, private enterprise had been allowed to take over other areas of business.

In the late 1980s dissent again resurfaced in Zanzibar, culminating in the revelation in January 1993 that Zanzibar had joined the Organization of the Islamic Conference. Criticism on the mainland forced its withdrawal later that year.

In May 1992 the country’s constitution was amended to provide for a multiparty political system, and in 1995 the first national elections under this system were held; Benjamin Mkapa of the CCM was elected president. Mkapa continued the economic reforms pursued by his predecessors.

• Challenges into the 21st century

Beginning in the mid-1990s and continuing into the 2000s, Tanzania’s already-tenuous economy and food supply were strained by the number of refugees arriving from the neighbouring countries of Rwanda, Burundi, and Zaire (now the Democratic Republic of the Congo); the country eventually requested international aid to assist with the care of the refugees. Meanwhile, Tanzania was the site of a terrorist act in 1998 when the U.S. embassy in Dar es Salaam was bombed; 11 people were killed, and many more were injured.

Mkapa was reelected in late 2000 amid allegations of electoral fraud in Zanzibar. Several violent demonstrations followed, including one in January 2001 in which police intervention resulted in at least 40 people dead and 100 people injured. Zanzibar also experienced an escalation in Islamic militancy. Several demonstrations, violent attacks, and bombings in the 2000s were attributed to a few radical organizations protesting the government’s refusal to comply with their extremist views. In late 2004, 10 people were killed in Dar es Salaam by the Indian Ocean tsunami; the government was criticized for not doing enough to warn the public about the impending threat.

After more than a decade of preparation, Tanzania, Uganda, and Kenya launched the East African Community Customs Union in 2005 in an effort to stimulate economic activity in the region. In 2009 Tanzania signed an agreement providing for the free movement of people and goods across the East African Community, which by this time also included Burundi and Rwanda.

Meanwhile, Tanzania’s concurrent presidential and legislative elections were held on December 14, 2005. Former foreign minister Jakaya Mrisho Kikwete, the CCM candidate, was elected president; the CCM itself won a strong majority in the National Assembly. In the 2010 presidential and legislative elections, held on October 31, Kikwete won a second term as president, with 61 percent of the vote. The CCM, though losing some seats to the opposition, maintained a majority in the National Assembly. The elections were marred by allegations from several opposition groups claiming that votes were tampered with, and some domestic and international observers noted issues with the transparency of the vote-tabulation process.

Earlier that year, Zanzibar had held a referendum to decide on whether to form a government of national unity after the October elections; some 66 percent of voters opted in favour of the measure. In the following years, however, there were demands for greater independence as well as some calls for secession from Tanzania.

Corruption, long an issue in Tanzania, remained a troubling problem under Kikwete’s administration, despite his pledges and efforts to curb the malfeasance. Of particular note was Edward Lowassa, a prominent CCM member and ally of Kikwete, who had been prime minister but resigned in 2008 after being implicated in a corruption-related case; Lowassa denied the allegations. Two other ministers also resigned over the same scandal that year, and shortly thereafter Kikwete dismissed his entire cabinet. Another corruption-related cabinet purge came in 2012 when Kikwete fired six ministers for alleged widespread misuse of government funds. Although some members of government had been put on trial for corruption-related charges, convictions were rare. An exception occurred in July 2015 when former ministers Basil Mramba and Daniel Yona were each sentenced to three years in prison for corruption-related charges.

Kikwete saw the drafting of a new constitution during his second term. He first suggested a constitutional review in 2011, and the following year a commission was established to proceed. After gathering much input from Tanzanians across the country as well as constitutional law experts, the commission made several recommendations, including a move to a decentralized three-tier system of government. A constituent assembly—consisting of the members of the Tanzanian National Assembly and the Zanzibar House of Representatives as well as more than 200 delegates from civil society organizations—reviewed the recommendations and were charged with approving a draft that would be put to a national referendum; a two-thirds majority vote by the body was needed for approval. Many CCM members participating in the constituent assembly did not support the recommendation of changing to a decentralized government, fearing that the outcome of such a change would favour the opposition, while much of the opposition strongly supported the recommendation; this led to an impasse. Unhappy with the way the draft discussions were proceeding, in 2014 the leading opposition party, Chadema, and other opposition groups formed a coalition, Ukawa, and boycotted the constituent assembly in an attempt to have their grievances over the proceedings heard. That act, along with a hastily called and questionable vote on the draft by the rest of the assembly, led to a draft version’s being approved for referendum that did not include the three-tier government structure. Although the goal had been for the constitutional referendum to be held before the October 2015 presidential and legislative elections, in April the electoral commission announced that the referendum would need to be delayed.

With Kikwete due to step down after two terms as president, the CCM began the process of choosing a candidate for the 2015 presidential election. In July 2015 it selected government minister John Magufuli, who had a reputation for being ethical and tough on corruption. Longtime CCM stalwart and former prime minister Lowassa left the party after Magufuli’s selection, angered at being passed over for the spot; he soon joined Chadema. Chadema, meanwhile, had worked to increase its appeal and gain supporters; by 2014 it had become increasingly popular with younger voters. The party and its allies in the Ukawa coalition its very existence noteworthy for being the first time in Tanzania’s history that the usually fractured opposition had united—agreed to field one candidate for the presidential election. Soon after Lowassa joined Chadema, he was named the presidential candidate of the coalition.

The presidential and parliamentary elections on October 25, 2015, were the country’s most closely contested polls, partly because of anger over corruption and the united front provided by the opposition. As results began to trickle in, it was clear that several CCM cabinet members had lost their legislative seats to Ukawa candidates. On October 28 the Zanzibar Electoral Commission chairman annulled the elections there, claiming that electoral laws had been violated; international observers were concerned with the annulment, feeling that it was unwarranted. Also that day, Lowassa called for a recount of the presidential vote, claiming that there were irregularities. Regardless, presidential results were released the next day, with Magufuli declared the winner with about 58 percent of the vote; Lowassa took almost 40 percent. Despite the loss of some seats, the CCM managed to maintain a majority in the National Assembly.

Zanzibar’s local presidential and parliamentary elections were rerun on March 20, 2016. The leading opposition party, the Civic United Front (CUF), maintaining that its candidate, Seif Sharif Hamad, had fairly won the October 2015 Zanzibar presidential election, boycotted the rerun. As such, the incumbent, Pres. Ali Mohamed Shein of the CCM, won more than 90 percent of the votes. Several diplomats reiterated their earlier position that the October election should not have been annulled and rerun.
