Mohamed Farrah Hassan Aidid (Somali: Maxamed Faarax Xasan Caydiid, Arabic: محمد فرح حسن عيديد; December 15, 1934 – August 1, 1996) was a Somali military commander and political leader. A former general and diplomat, he was the chairman of the United Somali Congress (USC) and later led the Somali National Alliance (SNA). Along with other armed opposition groups, they drove out President Mohamed Siad Barre's socialist regime from Somalia's capital Mogadishu during the Somali Civil War that broke out in the early 1990s.
In 1992, Aidid attacked United Nations troops in the nation. He was one of the main targets of the Unified Task Force. After eventually forcing UN forces to withdraw in 1995, Aidid declared himself President of Somalia until he was killed the following year.
