Zanzibar was a British protectorate from the end of World War One to 1963, when it briefly became independent. The revolution of 1964 was followed by a merger with Tanganyika later that year to form first the United Republic of Tanganyika and Zanzibar and later Tanzania. The Zanzibar-based Afro-Shirazi Party (ASP) was the junior partner in government with Julius Nyerere's Tanganyika African National Union (TANU) until 1977, when the two parties merged to form Chama Cha Mapinduzi (Revolutionary Party, CCM). As well as ASP materials there are also holdings for other parties dating back to the period of British control over Zanzibar.
