Axis occupation of Greece during World War II in the context of "Battle of Greece"

Cham Albanians or Chams (also spelled Çam Albanians or Çams; Albanian: Çamët; Greek: Τσάμηδες, romanized: Tsámides), are a subgroup of Albanians who originally resided in a region along the coast of the Ionian Sea in southwestern Albania and northwestern Greece, an area known among Albanians as Chameria. The Chams have their own particular cultural identity within Albanian subgroups. A number of Chams contributed to the Albanian national identity and played an important role in starting the renaissance of the Albanian culture in the 19th century. The Chams speak their own dialect of the Albanian language, the Cham Albanian dialect, which is a Southern Tosk Albanian dialect and one of the two most conservative ones; the other being Arvanitika.

During the late 1930s Chams suffered from intimidation and persecution under the dictatorship of General Metaxas. Following the Italian occupation of Albania in 1939, the Chams became a prominent propaganda tool for the Italians and irredentist elements among them became more vocal. As a result, on the eve of the Greco-Italian War, Greek authorities deported the adult male Cham population to internment camps. After the occupation of Greece, parts of the Muslim Cham population collaborated with Italian and German forces. This fueled resentment among the local Greek population and in the aftermath of World War II, the entire Muslim Cham population were forcefully expelled to Albania.

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. As a result of this pro-Albanian approach, many Muslim Chams actively supported the Axis operations and committed a number of crimes against the local population both in Greece and Albania. Apart from the formation of a local administration and armed security battalions, a paramilitary organization named Këshilla and a resistance paramilitary group called Balli Kombetar Cam were operating in the region, manned by local Muslim Chams. The results were devastating: many Greek and Albanian citizens lost their lives and a great number of villages were burned and destroyed. It appears that the Mufti and many beys did not approve of the Cham helping the Wehrmacht to burn Greek villages. With the retreat of the Axis forces from Greece in 1944, most of the Cham population fled to Albania and revenge attacks against the remaining Chams were carried out by Greek guerrillas and villagers. When the war ended, special courts on collaboration sentenced 2,106 Chams to death in absentia. However, the war crimes remained unpunished since the criminals had already fled abroad. According to German historian Norbert Frei, the Muslim Cham minority is regarded as the "fourth occupation force" in Greece due to the collaborationist and criminal activities that large parts of the minority committed.

According to the Lieutenant Colonel Palmer of the British Military Mission in Albania, 2,000–3,000 collaborated in an organized manner, while a report of Pan-Epirotic EAM-Commission names 3,200 Cham collaborators from the Dino clan. Although not everyone in the community actively collaborated, historiography agrees that the Cham minority completely accepted the Axis occupation and benefited from the presence of occupation troops by providing them with guides, connections, informants and other forms of support. Mainly due to their collaboration in World War II the Chams later became a controversial if not suspect community for the leaders of the People's Republic of Albania (1945-1991).
