In late January 1991 rebel forces of the United Somali Congress captured Mogadishu and drove the longtime dictator Mohamed Siad Barre from power, and he fled the capital, beginning the collapse of the Somali state into prolonged civil war. Barre had ruled Somalia since a 1969 coup, but by 1990 his authority had disintegrated amid clan-based insurgencies. In December 1990 a clan-based uprising erupted in Mogadishu against his regime.
On January 26, 1991, after weeks of fighting, forces loyal to the United Somali Congress of the Hawiye clan captured and held Mogadishu, and Barre fled the city on or about January 26 to 27, 1991. His departure did not bring peace: the USC split, and rival factions under Ali Mahdi Muhammad and General Mohamed Farah Aidid soon fought for control, plunging Somalia into a devastating civil war and state collapse.

On 17 November 1991 full-scale fighting started between the two factions of the USC headed by Ali Mahdi and Aydid, and by the end of March 1992 Human Rights Watch estimated that up to 14,000 people had been killed as Mogadishu was split between forces loyal to the two men.

On 18 May 1991 the former British protectorate of Somaliland, anxious to separate itself from the chaos in the rest of Somalia, declared independence, a territory not internationally recognized, illustrating the fragmentation that followed Barre's fall.

Editorial Note
Fate coding: the deposed president Mohamed Siad Barre fled Mogadishu in late January 1991 as the USC rebels took the capital, and he ultimately left the country, matching the dataset's fled-the-country fate; he was not killed. Coding note: the dataset labels this a rebel coup, accurately, the capture of the capital by an insurgent clan-based movement. Date nuance: the dataset dates this January 26, 1991; sources place Barre's flight from Mogadishu on or about January 26 to 27, 1991, and the late-January timing is recorded. Mass-violence context handled neutrally and cited: Barre's fall did not end the violence but began the collapse of the Somali state; the victorious USC split almost immediately between Ali Mahdi and Aidid, and the ensuing civil war killed many thousands (one estimate cites up to 14,000 by early 1992) and led to famine and eventual international intervention; these are recorded as documented context rather than adjudicated. Historical weight recorded: this ended Barre's rule since his own 1969 coup and marked the start of Somalia's long period of statelessness. Neutrality maintained on a contested subject.
Cross-Reference
Only one dataset carries it. One of the three reference datasets we check against carries this event; the others do not list it. That is not a contradiction — the datasets cover different periods and use different thresholds — but it means the record has had less outside corroboration.
Identifiers for finding this same event in the other datasets:
Coup Atlas research identifies the target as: President Mohamed Siad Barre, driven from Mogadishu by the USC rebels in late January 1991; he fled the capital and ultimately the country..
Baseline coding: Incumbent executive removed from power. Recorded leader fate: deposed; fled the country. The baseline file does not name individual targets; researched names are kept in a separate layer.
