Somalia has had no functioning government since January 1991, when former President Siad Barre was ousted.
Since that time, fighting between Somali warlords, government forces and various alliances of Islamist insurgents has resulted in the deaths of hundreds of Somalis and the displacement of hundreds of thousands.
One of the boldest attempts to turn a new page in Somalia and end a famine was the US Restore Hope intervention in 1992, which however, ended in failure in October 1993.
In the north, the former British protectorate of Somaliland declared its independence from the rest of Somalia in May 1991, and in 1998 the northeastern region of Puntland declared itself an autonomous state. Both regions have remained largely peaceful.
