Tanzania Emigration and Immigration

Immigration

 * German rule began in mainland Tanzania during the late 19th century when Germany formed German East Africa. This was followed by British rule after World War I.
 * The mainland was governed as Tanganyika, with the Zanzibar Archipelago remaining a separate colonial jurisdiction. Following their respective independence in 1961 and 1963, the two entities merged in 1964 to form the United Republic of Tanzania. The countries had joined the British Commonwealth in 1961 and Tanzania is still a member of the Commonwealth as one republic.
 * The population includes people of Arab and Indian origin, and small European and Chinese communities. Thousands of Arabs and Indians were massacred during the Zanzibar Revolution of 1964. As of 1994, the Asian community numbered 50,000 on the mainland and 4,000 on Zanzibar. An estimated 70,000 Arabs and 10,000 Europeans lived in Tanzania.

Emigration

 * Claiming the coastal strip, Omani Sultan Said bin Sultan moved his capital to Zanzibar City in 1840. During this time, Zanzibar became the centre for the east African slave trade. Between 65 and 90 per cent of the Arab-Swahili population of Zanzibar was enslaved. Figures record the exporting of 718,000 slaves from the Swahili coast during the 19th century, and the retention of 769,000 on the coast.mIn the 1890s, slavery was abolished.
