About Zanzibar

The presence of microlithic tools attests to 20 000 years of human occupation of Zanzibar. The islands became part of the historical record of the wider world when Arab traders discovered them and used them as a base for voyages between Arabia, India, and Africa. Unguja offered a protected and defensible harbour, so although the archipelago offered few products of value, the Arabs settled at what became Zanzibar City (Stone Town) as a convenient point from which to trade with East African coastal towns. They established garrisons on the islands and built the first mosque in the Southern hemisphere. During the Age of Exploration, the Portuguese Empire was the first European power to gain control of Zanzibar, and kept it for nearly 200 years. In 1698 Zanzibar fell under the control of the Sultanate of Oman, which developed an economy of trade and cash crops, with a ruling Arab elite. Plantations were developed to grow spices, hence the moniker of the Spice Islands (a name also used of Dutch colony the Moluccas, now part of Indonesia). Another major trade good was ivory, the tusks of elephants killed in mainland Africa. The third pillar of the economy was slaves, giving Zanzibar an important place in the Arab slave trade, the Indian Ocean equivalent of the better-known Triangular Trade. Zanzibar City was the main trading port of the East African slave trade, with about 50 000 slaves a year passing through the city. The Sultan of Zanzibar controlled a substantial portion of the East African coast, known as Zanj, which included Mombasa and Dar es Salaam, and trading routes which extended much further inland, such as to Kindu on the Congo River. Sometimes gradually, sometimes by fits and starts, control came into the hands of the British Empire; part of the political impetus for this was the 19th century movement for the abolition of the slave trade. The relationship between Britain and the nearest relevant colonial power, Germany, was formalized by the 1890 Helgoland-Zanzibar Treaty, in which Germany pledged not to interfere with British interests in insular Zanzibar. That year, Zanzibar became a protectorate (not a colony) of Britain. From 1890 to 1913, traditional viziers were appointed to govern as puppets, switching to a system of British residents (effectively governors) from 1913 to 1963. The death of one sultan and the succession of another of whom the British did not approve led to the Anglo-Zanzibar War. On the morning of 27 August 1896, ships of the Royal Navy destroyed the Beit al Hukum Palace; a cease fire was declared 45 minutes later, and the bombardment subsequently became known as The Shortest War in History.
