1981 Mauritanian coup attempt

The 1981 Mauritanian coup attempt was a violent coup attempt in Mauritania which took place on 16 March 1981.
The coup attempt, staged by elements of the military and opposition Alliance for a Democratic Mauritania movement, was led by Lieutenant-Colonel Ahmed Salim Ould Sidi and Lieutenant-Colonel Mohamed Abdelkader, and resulted in heavy fighting in the capital Nouakchott, before conspirators were defeated by troops loyal to the Head of State, Colonel Mohamed Khouna Ould Haidalla.
Abdelkader and Sidi were both subsequently executed after the coup attempt.
On 25 April, Haidalla and the CMSN decided to replace the fledgling civilian government of Sid'Ahmed Ould Bneijara with a six-member military government headed by Colonel Maaouya Ould Sid'Ahmed Taya.
