The Ogaden war between Ethiopia and Somalia was caused by boundary disputes. In the late 1970s, Somalia sought to take control of the Ogaden region, which was mainly inhabited by ethnic Somalis but was part of Ethiopia. Somalia claimed that the region rightfully belonged to them and that Ethiopia was illegally occupying it. Ethiopia, however, was not willing to relinquish control of the region. This led to a full-blown war between the two countries in 1977, which lasted for several months before Ethiopia emerged victorious.
