The People's Democratic Republic of Ethiopia (PDRE) was the official name of Ethiopia from 1987 to 1991, as established by the Communist government of Mengistu Haile Mariam and the Workers' Party of Ethiopia (WPE). Its creation led to the dissolution of the Derg, the military junta formerly in charge of the country. A socialist one-party state with the WPE as supreme authority, took its place, though the WPE's leadership was dominated by the surviving members of the Derg.
