—Zanzibari, adj., n./zan"zeuh bahr', zan'zeuh bahr"/, n.1. an island off the E coast of Africa: with Pemba and adjacent small islands it formerly comprised a sultanate under British protection; became independent in 1963; now part of Tanzania. 421,000; 640 sq. mi. (1658 sq. km).2. a seaport on W Zanzibar, Tanzania.
* * *Chief island (pop., 1995 est.: 456,934) of Tanzania.Located in the Indian Ocean off the coast of east-central Africa, it has an area of 637 sq mi (1,651 sq km). Zanzibar city (pop., 1988: 157,634), the island's principal port and commercial centre, is on the western side. Both Zanzibar and Pemba islands are believed to have once formed part of the African continent. In the late 17th century it came under the control of Omani Arabs, and the sultan of Oman made Zanzibar city his capital in 1832. In 1861 Zanzibar was separated from Oman and became an independent sultanate composed of the island, Kenya, Mafia Island, and the coasts of Tanzania and Somalia. Under Sultan Barghash (r. 1870–88), most of the mainland territories were lost to European powers. In 1890 the British proclaimed a protectorate over Zanzibar and Pemba islands. In 1963 the sultanate regained its independence and became a member of the Commonwealth. The sultanate was overthrown in 1964, and a republic was established. It then joined with Tanganyika to form the Republic of Tanzania. The economy depends on agriculture and fishing.
* * *▪ TanzaniaSwahili Ungujacity and port of the island of Zanzibar, Tanzania. The island's principal port and commercial centre, it is on the western side of the island behind a well-protected natural deepwater harbour. In 1824 Sultan Saʿīd ibn Sulṭān of Oman established his capital there, shifting it from Muscat on the Arabian Peninsula. During the remainder of the 19th century, the city flourished as the base for Arab and European activities in eastern Africa, becoming infamous for its trade in slaves. Zanzibar subsequently declined in importance as the ports of Dar es Salaam and Mombasa (on the coast of the eastern African mainland) took over much of its trade. Zanzibar's port is still a major exporter of cloves, coconuts, citrus fruits, and other tropical products. Pop. (2002) 205,807.Swahili Ungujaisland in the Indian Ocean 22 miles (35 km) off the coast of east-central Africa. In 1964 Zanzibar, together with Pemba Island (q.v.) and some other smaller islands, joined with Tanganyika on the mainland to form the United Republic of Tanzania. Zanzibar island covers 637 square miles (1,651 square km).Both Zanzibar and Pemba are believed to have once formed part of the African continent, the separation of Pemba having occurred during the Miocene epoch (23.7 million to 5.3 million years ago) while Zanzibar dates from the Pliocene epoch (5.3 million to 1.6 million years ago) or even later. Various types of limestone form the base of both islands. Raised sands and sandstones also occur, together with varied residual deposits similar to alluvial strata on the adjacent mainland. Extensive weathering of the limestones combined with erosion and earth movements have resulted in a variety of soils including red earths, loams, clays, and sands. Flat areas of coral limestone occur to the east, south, and north of Zanzibar and on the western islands. In places the coral is overlain by shallow red earth or alluvium.The general impression of Zanzibar when approached from the mainland is of a long, low island with small ridges along its central north–south axis. Coconut palms and other vegetation cover the land surface. It is 53 miles (85 km) at its greatest length and 24 miles (39 km) broad. The highest point of the central ridge system is Masingini, 390 feet (119 m) above sea level. Higher ground is gently undulating and gives rise to a few small rivers, which flow west to the sea or disappear in the coral country.The climate is typically insular, tropical, and humid, with an average annual rainfall of 60 to 80 inches (1,500 to 2,000 mm). Rainfall is reliable and well-distributed in comparison with most of eastern Africa. Northeast trade winds blow from December to March and southeast trade winds from May to October. The “long rains” occur between March and May and the “short rains” between October and December.Small patches of indigenous forest and isolated large trees support the view that much of the island was originally covered by dense evergreen forest. The open coral-outcrop country supports a dense thicket vegetation. The flat clay plains are grass-covered. The major wild animals include leopard (a variety peculiar to Zanzibar), civet cat, mongoose, two species of monkey, lemur, the African pig, forest duiker, pigmy antelope, about 20 species of bats, and 30 forms of snakes. Mosquitoes breed freely during the rainy seasons. Insect pests such as the coreid bug (Pseudotheraptus wayi), which attacks coconuts, and animal pests and parasites, such as tsetse fly and ticks (which transmit east coast fever to cattle), have been the subject of research and control.The southern and eastern portions of Zanzibar island have been mainly populated by a Bantu-speaking people known as the Hadimu; the northern portion of Zanzibar island and the adjacent Tumbatu island have been occupied by another Bantu-speaking people known as the Tumbatu. These two groups represent the earliest arrivals in Zanzibar. Throughout the 19th century, and after, they were expropriated from the western and more fertile parts of the island by later arrivals, notably Arabs (Arab). The nationalization of land in 1964, however, was followed by economic reforms that redistributed the land. Fishing has traditionally been highly important in coastal villages and remains so.The language most widely spoken is a highly Arabicized form of Swahili (Kiswahili). Among the Arabs, the language of the home is usually Swahili, and use of pure Arabic is confined to scholars and recent arrivals from Arabia. Gujarati, Hindī, Urdu, and Konkani are spoken by the Asian communities, and English and Swahili are widely used and understood.Before the development of eastern African mainland ports, Zanzibar was the trade focus of the region and enjoyed an important entrepôt trade. The island's economy now depends on agriculture and fishing.Considerable areas of fertile soil and a favourable climate enable the production of a variety of tropical crops, most importantly cloves and coconuts. Local food crops, such as rice, cassava, yams, and tropical fruit, are also important. Fish is an important part of the diet, and local fisheries employ perhaps about one-tenth of the population.Zanzibar's history was greatly shaped by its geography, the prevailing winds of the region placing it directly on the Indian Ocean trade routes and making it accessible to both traders and colonists from Arabia, south Asia, and the African mainland. The first immigrants were the Africans; the next were the Persians, who began to land in Zanzibar in the 10th century and who, over a brief period, became absorbed into the local population and disappeared as a separate group. Their influence was left in the gradual consolidation of disparate villages and rural populations into what came to be recognized as two peoples, the Hadimu and the Tumbatu. This African-Persian population converted to Islām and adopted many Persian traditions. (Even today, most of Zanzibar's African population calls itself “Shirazi,” in echo of the ancient Persian principality of Shīrāz, from which the earliest Persians came.)Arabs had the deepest influence on Zanzibar, because the island's position made it a perfect entrepôt for Arabs mounting slave expeditions into Africa and conducting oceangoing commerce. Arabs from Oman became especially important, for they began establishing colonies of merchants and landowners in Zanzibar. Eventually they became the aristocracy of the island.The Portuguese then came in the 16th century and conquered all the seaports on the eastern African coast, including Mombasa, the richest and most powerful, as well as such islands as Zanzibar and parts of the Arabian coast, including the Omani capital of Muscat. The purpose of the Portuguese, however, was largely commercial rather than politically imperial, and, when their power dwindled in the course of the 17th century, they left few marks of their stay.The Omani Arabs, who expelled the Portuguese from Muscat in 1650 and were the leading force against them in the entire region, gradually established at least nominal control over many settlements, including Zanzibar. After a lengthy turmoil of dynastic wars and losses and gains on the African coast, the ruling sultan of Oman, Saʿīd ibn Sulṭān, decided to relocate his capital from Muscat to Zanzibar. The rapid expansion of the slave trade in the late 18th and early 19th centuries, caused by the demand for plantation slaves in North and South America, made Zanzibar central to the slave (as well as the ivory) trade routes into the interior of Africa. Zanzibar itself also had significant resources of coconuts, cloves, and foodstuffs. The sultan of Oman made it his capital in 1832.In 1861 Zanzibar was separated from Oman and became an independent sultanate, which controlled the vast African domains acquired by Saʿīd. Under the sultan Barghash (reigned 1870–88), however, Great Britain (British Empire) and Germany divided most of Zanzibar's territory on the African mainland between them and secured economic control over the remaining coastal strip. In 1890 the British proclaimed a protectorate over Zanzibar itself; the sultan's authority was reduced and the slave trade curtailed.In 1963 the sultanate regained its independence, becoming a member of the British Commonwealth. In January 1964 a revolt by leftists overthrew the sultanate and established a republic. The revolution marked the overthrow of the island's long-established Arab ruling class by the Africans, who were the majority of the population. In April the presidents of Zanzibar and Tanganyika signed an act of union of their two countries, creating what later in the year was named Tanzania (q.v.). Pop. (2002) 622,459.
