The 1969 Somali coup d'état was a bloodless military takeover of the Somali Republic on 21 October 1969, led by Somali National Army officers of the Supreme Revolutionary Council under General Siad Barre. After the assassination of President Abdirashid Shermarke in Las Anod, the Somali National Army under Barre's command stormed Mogadishu, seized key government buildings, and demanded the resignation of the country's leaders. The coup deposed acting President Sheikh Mukhtar Hussein and Prime Minister Mohammad Egal, ushering in a 21-year military rule under Barre and the establishment of an authoritarian government that lasted until 1991.
The coup arose from the political tensions and highly contested parliamentary elections of March 1969. It was the first successful coup, following a failed attempt in 1961. With the establishment of Supreme Revolutionary Council rule, the Somali Republic was replaced by the socialist Somali Democratic Republic, which governed until its collapse in 1991.
