Quick Summary

Ali Mohamed Shein is a Tanzanian politician who served as the president of Zanzibar from 2010 to 2020. He is a member of the Chama Cha Mapinduzi (CCM) party.12

Shein's presidency followed a period of political contention in Zanzibar, including the annulment and rerun of the 2015 elections. In the rerun election held in March 2016, Shein won over 90 percent of the votes, though international observers expressed concerns about the annulment of the initial election. Zanzibar and mainland Tanganyika merged in 1964 to form Tanzania, with Shein's tenure occurring within this unified nation.12
