The Zanzibar Revolution began on 12 January 1964 and led to the overthrow of the Sultan of Zanzibar and his mainly Arab government by the island's majority Black African population.

Zanzibar is an insular semi-autonomous region which united with Tanganyika in 1964 to form the United Republic of Tanzania. It is an archipelago in the Indian Ocean, 25–50 km (16–31 mi) off the coast of the African mainland, and consists of many small islands and two large ones: Unguja and Pemba Island. The capital is Zanzibar City, located on the island of Unguja. Its historic centre, Stone Town, is a World Heritage Site.
