The National Republican Greek League was a major anti-Nazi resistance group formed during the Axis occupation of Greece during World War II.
The largest of the non-communist resistance groups, its military wing, the National Groups of Greek Guerrillas (Εθνικές Ομάδες Ελλήνων Ανταρτών, Ethnikés Omádes Ellínon Antartón (ΕΟΕΑ)) concentrated its military activities in Epirus. From 1943 onwards, EDES came into confrontation with the communist-led National Liberation Front, beginning a series of civil conflicts that would lead to the Greek Civil War.
