ティグレ人民解放戦線
At the end of the 1980s, the Soviet Union informed Mengistu that it would not be renewing its defence and cooperation agreement. With the cessation of Soviet support and supplies, the Ethiopian Army's morale plummeted, and the EPLF, along with other Ethiopian rebel forces, began to advance on Ethiopian positions. The joint effort to overthrow the Mengistu, Marxist regime was a joint effort of mostly EPLF forces, united with other Ethiopian faction groups primarily consisting of tribal liberation fronts (for example: the Oromo Liberation Front, the Tigrayan People's Liberation Front – who were jointly in battles against the ELF and other key battles where many Tigrayans were lost in the Eritrean Civil Wars – and the EPRDF, a conglomerate of the current TPLF regime and the marxist Oromo People's Democratic Organization who became prominent for recruiting Derg defectors as the EPLF and EPRDF occupied parts of the provinces of Wollo and Shewa in Ethiopia).
