The Oromo and other nations and nationalities in Ethiopia who felt their rights have been violated protested and revolted against these subjugations and dominations. For example, in 1991, at the end of Derg Government, there were seventeen armed organizations fighting the central government of Ethiopia (Bereket Simon, Tnsa’e ZeItiyophiya Kementa Menged, 2010 E.C, p.15).The majority of these armed organizations were, some of them still are, liberation fighters including Eritrea People’s Liberation Front (EPLF), Tigray People’s Liberation Front (TPLF), Afar Liberation Front (ALF), Oromo Liberation Front (OLF), Islamic Front for the Liberation of Oromia (IFLO), Ogaden National Liberation Front (ONLF), Western Somali Liberation Front (WSLF), Beneshangul People’s Liberation Movement (BPLM), Gambella People’s Liberation Movement (GPLM), and Sidama Liberation Movement (SLM).This makes “liberation” which usually necessitates revolution a long standing demand in Ethiopian politics.
