The Ethiopian People's Revolutionary Party (EPRP) (Amharic: የኢትዮጵያ ሕዝባዊ አብዮታዊ ፓርቲ, romanized: Ye-Ītyōṗṗyā Həzbāwī Abyotawi Party), informally known as Ihapa (Amharic: ኢሕአፓ), is the first modern political party in Ethiopia. Established in April 1972, it aimed to turn Ethiopia into a democratic republic. Both the EPRP and another party, the All-Ethiopia Socialist Movement (MEISON) were enthusiastic supporters of the student-led 1974 Ethiopian Revolution that eventually led to the toppling of Emperor Haile Selassie and abolishing the monarchy the following year. However, following the rise of Mengistu Haile Mariam to power as leader of the ruling Derg, the military junta that had taken control of Ethiopia, ideological conflict developed between the various groups.
