The Ethiopian People's Revolutionary Democratic Front was an ethnic federalist political coalition in Ethiopia that existed from 1988 to 2019. It consisted of four political parties: Tigray People's Liberation Front (TPLF), Amhara Democratic Party (ADP), Oromo Democratic Party (ODP) and Southern Ethiopian People's Democratic Movement (SEPDM). After leading the overthrow of the People's Democratic Republic of Ethiopia, it dominated Ethiopian politics from 1991 to 2019. In November 2019, the EPRDF was dissolved, and Prime Minister and EPDRF chairman Abiy Ahmed merged three of the constituent parties into his new Prosperity Party, which was officially founded on 1 December 2019.
