Independent from France in 1960, Mauritania annexed the southern third of the former Spanish Sahara (now Western Sahara) in 1976, but relinquished it after three years of raids by the Polisario guerrilla front seeking independence for the territory. Maaouya Ould Sid Ahmed TAYA siezed power in a coup in 1984. Opposition parties were legalized and a new constitution approved in 1991. Two multiparty presidential elections since then were widely seen as flawed, but October 2001 legislative and municipal elections were generally free and open. A bloodless coup in August 2005 deposed President TAYA and ushered in a military council headed by Col. Ely Ould Mohamed VALL, which declared it would remain in power for up to two years while it created conditions for genuine democratic institutions and organized elections. For now, however, Mauritania remains an autocratic state, and the country continues to experience ethnic tensions among its black population and different Moor (Arab-Berber) communities.
