Abeid Karume

Karume led the Zanzibar Revolution in January 1964, overthrowing the Sultanate and establishing the People's Republic of Zanzibar. The revolution resulted in the overthrow of the Arab-dominated government and the installation of an Afro-Shirazi Party regime, leading to significant social and political changes.

Following the revolution, Karume became the first President of Zanzibar in 1964. He led the government until his assassination in 1972, implementing policies of nationalization and land redistribution, while also consolidating power through authoritarian means.

In April 1964, Karume negotiated the union of Zanzibar with Tanganyika to form the United Republic of Tanzania. This act created a single sovereign state, though Zanzibar retained significant autonomy, including its own president and government.

Karume was assassinated in April 1972 by four gunmen while playing chess at the Afro-Shirazi Party headquarters in Zanzibar City. His death led to a period of political instability and a crackdown on opposition, with his successor Aboud Jumbe taking power.
