Internal rebellion, government repression, and economic mismanagement characterized Mengistu's presidency, the Red Terror period being a battle for dominance between the Derg, the EPRP, and their rival the All-Ethiopia Socialist Movement (MEISON), which had initially aligned itself with the Derg. While this internal conflict was being fought, Ethiopia was threatened by both the Somali invasion and the guerrilla campaign of the Eritrean People's Liberation Front, who demanded independence for Eritrea, then a province of Ethiopia. The Ogaden War of 1977–1978 with Somalia, fought over a disputed border region (Ogaden), was notable for the prominent role of Mengistu's Soviet and Cuban allies in securing an Ethiopian victory. The catastrophic famine of 1983–1985 is what brought his government the most international attention.
