Stone Town
Stone Town, also known as Mji Mkongwe (Swahili for "old town"), is the old part of Zanzibar City, the main city of Zanzibar, in Tanzania. The newer portion of the city is known as Ng'ambo, Swahili for 'the other side'. Stone Town is located on the western coast of Unguja, the main island of the Zanzibar Archipelago. Former capital of the Zanzibar Sultanate, and flourishing centre of the spice trade as well as the slave trade in the 19th century, it retained its importance as the main city of Zanzibar during the period of the British protectorate. When Tanganyika and Zanzibar joined each other to form the United Republic of Tanzania, Zanzibar kept a semi-autonomous status, with Stone Town as its local government seat.
Julius Nyerere
Nyerere was also concerned by developments in Zanzibar, an island off of Tanganyika's coast. He noted that it was "very vulnerable to outside influences", which could in turn impact Tanganyika. Zanzibar secured independence from the British Empire in 1963, and in January 1964 the Zanzibar Revolution took place, in which the Arab Sultan Jamshid bin Abdullah was overthrown and replaced by a government consisting largely of indigenous Africans. Nyerere was taken by surprise by the revolution. Like Kenya and Uganda, he quickly recognised the new government, although allowed the deposed Sultan to land in Tanganyika and from there fly to London. At the request of the new Zanzibar government, he sent 300 policemen to the island to help restore order.
