Ethiopian-Somali War

The Ethio-Somali War, Ethiopian-Somali War or the Ogaden War, was a conventional conflict between Somalia and Ethiopia in 1977 and 1978 over the Ogaden region of Ethiopia. In a notable illustration of the nature of Cold War alliances, the Soviet Union switched from supplying aid to Somalia to supporting Ethiopia, which had previously been backed by the United States, prompting the U.S. to start supporting Somalia. The war ended when Somali forces retreated back across the border and a truce was declared.
