History of Somalia Timeline
(c. 2500 BCE – Present)The history of Somalia spans thousands of years, beginning with ancient trade civilizations along the Horn of Africa, including the Land of Punt. Medieval Somalia saw the rise of powerful sultanates such as the Ajuran Empire and the Adal Sultanate. European colonization in the late 19th century divided Somali territories among Britain, Italy, and France, leading to independence and unification of British Somaliland and Italian Somaliland in 1960. The subsequent decades featured dictatorship under Siad Barre, a devastating civil war beginning in 1991, state collapse, and ongoing efforts toward peace, federal governance, and reconstruction.
