Cham Albanian collaboration with the Axis
During the Axis occupation of Greece between 1941 and 1944 parts of the Cham Albanian minority (Albanian: Çamë, Greek: Τσάμηδες, Tsámides) in the Thesprotia prefecture, northwestern Greece, collaborated with the occupation forces. Fascist Italian as well as Nazi German propaganda promised that the region would be awarded to Albania (then in personal union with Italy) after the end of the war.
