المختار ولد داداه
The country declared its independence in 1960 and established itself as an Islamic Republic. Independence brought Moktar Ould Daddah into power, who promoted Islam during his rule. A military coup d'état ousted Daddah in 1978. Colonel Mohamed Khouna Ould Haidalla, one of the participants of the coup, became head of the government in 1980, and implemented Sharia law. Maaouya Ould Sid'Ahmed Taya, successor of Ould Haidalla, reversed some of these changes, but was ousted in a military coup in 2005.
