Zanzibar Revolution

The Zanzibar Revolution by local African revolutionaries in 1964 overthrew the Sultan of Zanzibar and his mainly Arab government. An ethnically diverse state consisting of a number of islands off the east coast of Tanganyika, Zanzibar had been granted independence by Britain in 1963. Thereafter a series of parliamentary elections resulted in the Arab minority retaining the hold on power it had inherited from Zanzibar's former existence as an overseas territory of Oman. Frustrated by under-representation in Parliament despite winning 54% of the vote in the July 1963 election, the mainly African Afro-Shirazi Party (ASP) allied itself with the left-wing Umma Party, and early on the morning of 12 January 1964 ASP member John Okello mobilised around 600–800 revolutionaries on the main island of Unguja (Zanzibar Island). Having overrun the country's police force and appropriated their weaponry, the insurgents proceeded to Zanzibar Town where they overthrew the Sultan and his government. Reprisals against Arab and South Asian civilians on the island followed; the resulting death toll is disputed, with estimates ranging from several hundred to 20,000. The moderate ASP leader Abeid Karume became the country's new president and head of state, and positions of power were granted to Umma party members.

The new government's apparent communist ties concerned Western governments, and as Zanzibar lay within the British sphere of influence, the British government drew up a number of intervention plans. However, the feared communist government never materialised, and British and United States citizens were successfully evacuated, so these plans were not put into effect. Meanwhile, the communist bloc powers of P. R. China, East Germany and the Soviet Union established friendly relations with the new government by recognising the country and sending advisors. Karume negotiated a merger of Zanzibar with Tanganyika, forming the new nation of Tanzania; an act judged by contemporary media to be an attempt to prevent communist subversion of Zanzibar. The revolution ended 200 years of Arab dominance in Zanzibar, and is commemorated on the island each year with anniversary celebrations and a public holiday.
