In October 2000, Tanzania held its second multi-party general elections. The ruling CCM party’s candidate, Benjamin W. Mkapa, defeated his three main rivals, winning the presidential election with 71% of the vote. In the parliamentary elections, CCM won 202 of the 232 elected seats. In the Zanzibar presidential election, Abeid Amani Karume, the son of former President Abeid Karume, defeated CUF candidate Seif Shariff Hamad. The election was marred by irregularities, and subsequent political violence claimed at least 23 lives in January 2001, mostly on Pemba island, where police used tear gas and bullets against demonstrators. Hundreds were injured, and state forces were reported to have attacked boats of refugees fleeing to Kenya. Also, 16 CUF members were expelled from the Union Parliament after boycotting the legislature to protest the Zanzibar election results.
