Mengistu Haile Mariam

Mengistu Haile Mariam, as a member of the Derg military committee, participated in the coup that overthrew Emperor Haile Selassie. The Derg abolished the monarchy and established a Marxist-Leninist military government, with Mengistu emerging as its chairman by 1977.

Mengistu led Ethiopia in a war against Somalia over the Ogaden region. With massive military aid from the Soviet Union and Cuba, Ethiopian forces repelled the Somali invasion by March 1978, securing the disputed territory.

Mengistu ordered a violent crackdown against political opponents, primarily the Ethiopian People's Revolutionary Party (EPRP). Thousands were killed, tortured, or imprisoned in Addis Ababa and other cities, consolidating Mengistu's absolute control over Ethiopia.

During a severe famine that killed an estimated 1 million Ethiopians, Mengistu's government was criticized for prioritizing military spending and forced resettlement programs over relief. The regime's response was widely condemned internationally.

After years of civil war, rebel forces led by the Ethiopian People's Revolutionary Democratic Front (EPRDF) captured Addis Ababa. Mengistu fled to Zimbabwe, ending 17 years of his dictatorship and leading to the establishment of a transitional government.
