The 1969 Somali coup d'état establishes a Marxist–Leninist administration.

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.
