Tanzania (tăn'zənē'ə, –zăn'ēə, Swahili tänzänē'ä) , officially United Republic of Tanzania, republic (2005 est. pop. 36,766,000), 364,898 sq mi (945,087 sq km), E Africa, formed in 1964 by the union of the republics of Tanganyika and Zanzibar. For a description of the island of Zanzibar, and its history until 1964, see Zanzibar. Other islands include Pemba and Mafia as well as several smaller islands. Mainland Tanzania is bordered on the south by Mozambique, Malawi, and Zambia; on the west by Congo (Kinshasa), Burundi, and Rwanda; on the north by Uganda and Kenya; and on the east by the Indian Ocean. Lake Nyasa forms part of the southern boundary, Lake Tanganyika part of the western boundary, and Lake Victoria part of the northern boundary. Dar-es-Salaam is the former capital and largest city of the republic. The Tanzanian legislature moved to the new capital of Dodoma in 1996, but many government offices remained temporarily in Dar-es-Salaam.
Land and People
Mainland Tanzania falls into three major geographical zones—a narrow lowland coastal strip along the Indian Ocean; a vast interior plateau; and a number of scattered mountainous regions. The coastal zone (10–40 mi/16–60 km wide) receives considerable rainfall and has much fertile soil. The plateau (average elevation: 3,500–4,500 ft/1,070–1,370 m) extends over most of the interior and is cut in two places by branches of the Great Rift Valley. The western branch contains Lake Tanganyika and the eastern branch runs through central Tanzania about 500 ft (150 m) below the level of the plateau; the two branches merge just north of Lake Nyasa. The plateau receives little rainfall, but in most parts there is enough to support agriculture.
The Serengeti National Park, one of the country's several wildlife reserves, is east of Lake Victoria, and Lake Rukwa is in the southwest. The mountainous regions include Mt. Meru (14,979 ft/4,566 m) and Mt. Kilimanjaro (19,340 ft/5,895 m, the highest point in Africa) in the northeast; the Usambara, Nguru, and Uluguru mts. in the east; the Livingstone Mts. and the Kipengere Range near Lake Nyasa in the south; and the Ufipi Highlands in the southwest. Tanzania's few rivers include the Pangani, the Rufiji, and the Ruvuma (which forms part of the border with Mozambique), all of which flow into the Indian Ocean, and the Malagarasi River, which flows into Lake Tanganyika. In addition to Dar-es-Salaam and Dodoma, other important towns on the mainland include Arusha, Iringa, Kigoma, Morogoro, Mbeya, Moshi, Mtwara, Mwanza, Tabora, and Tanga.
Virtually all of Tanzania's inhabitants speak Bantu languages. There are approximately 130 ethnic groups. Inhabitants of Indian and Arab descent constitute approximately 1% of the population and are concentrated in Zanzibar. The Bantu-speaking peoples include the Sukuma (the republic's largest ethnic group), Bena, Chagga, Gogo, Ha, Haya, Hehe, Luguru, Makonde, Makua, Ngoni, Nyakyusa, Nyamwezi, and Nyaturu. In addition, the Masai speak a Nilotic language; the Sandawe speak a language akin to Khoikhoi; and the Iraqw speak a Cushitic language. Swahili and English are the republic's official languages; Arabic is also spoken on Zanzibar. About 45% of the mainland population is Christian, while 35% is Muslim, and about 20% follow traditional religious beliefs. The population of Zanzibar is almost completely Muslim. Tanzania's urban population is growing rapidly.
Economy
The economy of Tanzania is overwhelmingly agricultural; plantations grow cash crops, including coffee, tea, pyrethrum, sisal, rice, peanuts, tobacco, sugarcane, cotton, copra, cashews, and cloves (cultivated in Zanzibar and Pemba). Most of the population, however, is engaged in subsistence farming, growing corn, wheat, millet, sorghum, vegetables, bananas, and cassava. In addition, large numbers of cattle, sheep, and goats are raised. Timber is important and includes mahogany, teak, ebony, camphor wood, and mangrove. Manufactures are largely limited to processed agricultural goods, beverages, paper, and basic consumer items. Refined petroleum, fertilizer, aluminum goods, and construction materials (especially cement) are also produced. Diamonds, tanzanite, and other gemstones are mined; other minerals extracted in significant quantities include gold, salt, gypsum, phosphates, and kaolin. There are also tin mines in NW Tanzania and coal and iron ore deposits near Lake Nyasa. Natural gas from deposits around Songo Songo Island, off the S central coast, are used to produce electricity.
Tanzania has limited road and rail networks. The main rail lines run from Dar-es-Salaam to Kigoma (on Lake Tanganyika) and to Tanga, Moshi, and Arusha in the NE. The Great Uhuru (Tanzam or Tazara) railroad, built in the 1970s by the Chinese, connects Dar-es-Salaam with central Zambia, affording landlocked Zambia an alternative route to the sea. Tanzania has a growing trade deficit, exacerbated by nationalization efforts. The exports are made up of agricultural goods and diamonds and other gemstones. The principal imports are consumer goods, machinery, transportation equipment, foodstuffs, refined petroleum, and chemicals. The leading trade partners are the European Union countries, Japan, Kenya, India, and the United States. Tanzania is a member of the Southern African Development Community.
Government
Tanzania operates under the constitution of 1977, as modified in 1984. The head of state and chief executive is the president, who is elected by popular vote for a five-year term. Political parties besides the ruling Party of the Revolution (CCM) were permitted starting in 1993, and the first multiparty elections were held in 1995. The republic's legislative body is the 274-seat national assembly. Zanzibar also has its own president and house of representatives, for dealing with matters internal to Zanzibar. Tanzania is divided into 26 administrative regions.
History
Early History
In 1959, Dr. L. S. B. Leakey, a British anthropologist, discovered at Olduvai Gorge in NE Tanzania the fossilized remains of what he called Homo habilis, who lived about 1.75 million years ago. Tanzania was later the site of Paleolithic cultures. By the beginning of the first millennium A.D. scattered parts of the country, including the coast, were thinly populated. At this time overseas trade seems to have been carried out between the coast and NE Africa, SW Asia, and India.
By about A.D. 900 traders from SW Asia and India had settled on the coast, exchanging cloth, beads, and metal goods for ivory. They also exported small numbers of Africans as slaves. By this time there were also commercial contacts with China, directly and via Sri Vijaya (see under Indonesia) and India. By about 1200, Kilwa Kisiwani (situated on an island) was a major trade center, handling gold exported from Sofala (on the coast of modern Mozambique) as well as goods (including ivory, beeswax, and animal skins) from the near interior of Tanzania. By about 1000 the migration of Bantu-speakers into the interior of Tanzania from the west and the south was well under way, and the population there had been greatly increased. The Bantu were organized in relatively small political units.
Foreign Contacts
In 1498, Vasco da Gama, the Portuguese explorer, became the first European to visit the Tanzanian coast; in 1502, on his second visit there, he made Kilwa tributary. In 1505, Kilwa was sacked by Francisco d'Almeida, another Portuguese explorer, and by 1506 Portugal controlled most of the coast of E Africa. The Portuguese did not cooperate with the local people, and their impact was mostly negative—trade was disrupted, towns declined, and people migrated from the region. However, Kilwa's trade seems to have grown as a result of contact with the Portuguese. Toward the end of the 16th cent., the Zimba, a group from SE Africa, moved rapidly up the coast, causing considerable damage; in 1587 they sacked Kilwa and killed about 3,000 persons (roughly 40% of its inhabitants).
In 1698 the Portuguese were expelled from the E African coast (except for a brief return in 1725) with the help of Arabs from Oman. In the early 18th cent., the Omanis showed some interest in the commerce of E Africa, and this increased after the Bu Said dynasty replaced the Yarubi rulers in 1741. Oman's commercial activity was centered on Zanzibar (and, to a lesser extent, at Mombasa), from which it controlled the overseas trade of E Africa. By the early 19th cent. numerous towns on the Tanzanian coast had been founded or revived; these included Tanga, Pangani, Bagamoyo, Kilwa Kivinje (situated on the mainland near Kilwa Kisiwani), Lindi, and Mikandani.
