The 1992 famine in Somalia was, in common with many famines, as much the result of the civil war as the climatic conditions. In 1991 President Barre was overthrown by opposing clans, but they failed to agree on a replacement and plunged the country into lawlessness and clan warfare. In December 1992 US Marines landed near Mogadishu ahead of a UN peacekeeping force sent to restore order and safeguard relief supplies. The US forces withdrew in 1993 following the debacle of the infamous 'Black Hawk Down' episode. For thirteen years after Barre's downfall, the country had no government, and was divided into fiefdoms ruled by rival warlords. In the summer of 2006, the warlords were finally forced out of Mogadishu by Islamist militias.
