Tigrayan People's Liberation Front
In the early 1990s, the Ethiopian Democratic People's Republic began to lose its control over Ethiopia. The OLF failed to maintain strong alliances with the other two rebel groups at the time; the Eritrean People's Liberation Front (EPLF) and the Tigrayan People's Liberation Front (TPLF). In 1990, the TPLF created an umbrella organization for several rebel groups in Ethiopia, the Ethiopian People's Revolutionary Democratic Front (EPRDF). The EPRDF's Oromo subordinate, the Oromo People's Democratic Organization (OPDO) was seen as an attempted replacement for the OLF.
