The 1969 Somali coup d'état was the bloodless takeover of Somalia's government on 21 October 1969 by military officers of the Supreme Revolutionary Council led by Siad Barre. Somali troops supported by tanks under the command of Barre stormed Mogadishu and seized key government buildings and ordered the resignation of the country's leaders. The coup deposed President Sheikh Mukhtar Mohamed Hussein and Prime Minister Mohammad Egal and led to the twenty-one year long military rule by Barre and the imposition of an authoritarian government in Somalia until 1991.

Mohammed Siad Barre was a Somali major general, politician and revolutionary who served as the third president of Somalia from 21 October 1969 to 26 January 1991.
