Maaouya Ould Sid'Ahmed Taya becomes the third president of Mauritania after a coup d'état against Mohamed Khouna Ould Haidalla while the latter is attending a summit.

A coup d'tat ( (listen); French for 'stroke of state'), also known as a coup or overthrow, is a seizure and removal of a government and its powers. Typically, it is an illegal seizure of power by a political faction, politician, cult, rebel group, military, or a dictator. Many scholars consider a coup successful when the usurpers seize and hold power for at least seven days.

Maaouya Ould Sid'Ahmed Taya (Arabic: معاوية ولد سيد أحمد الطايع, romanized: Ma‘āwiyah wuld Sīdi Aḥmad aṭ-Ṭāya‘ / Mu'awiya walad Sayyidi Ahmad Taya; born 28 November 1941) is a Mauritanian military officer who served as the President of Mauritania from 1984 to 2005. Having come to power through a bloodless military coup, he was ousted by a military coup himself in 2005. Prior to his presidency, he was the 5th Prime Minister of Mauritania between 1981 to 1992 (except for a brief period in 1984).
