Mengistu, born in 1937, took part in 1960 in the attempted coup against Haile Selassie and in 1977, and after a further coup, became undisputed Ethiopian ruler. He set out to create a socialist state in Ethiopia aligned with the communist block, but was overthrown in 1991 by the Ethiopian People's Democratic Front.
