Greek Civil War

The Greek Civil War was fought between the Greek government forces, supported by the United Kingdom and later the United States, and the Democratic Army of Greece (DSE), the military wing of the Communist Party of Greece (KKE). It is generally dated from 1946 to 1949, though violent clashes between resistance factions began during the German occupation and the brief Dekemvriana fighting in Athens in December 1944.

The conflict emerged from the fractured resistance to Axis occupation. The communist-led EAM/ELAS had been the largest wartime resistance organization, but the Varkiza Agreement of February 1945 disarmed ELAS without resolving the underlying political contest. After the 1946 elections, which the KKE boycotted, fighting resumed in the northern mountains.

The war became one of the first major proxy conflicts of the Cold War. In March 1947, President Harry Truman announced the Truman Doctrine, pledging US support to Greece and Turkey against communist pressure; Washington subsequently provided substantial military aid and advisors. The DSE received support and sanctuary from neighboring communist states, particularly Yugoslavia, Albania, and Bulgaria.

A turning point came with the Tito–Stalin split in 1948. Yugoslavia closed its border to the DSE in mid-1949, cutting off the insurgents' most important logistical lifeline. Combined with conventional government offensives in the Grammos and Vitsi mountains, this led to the DSE's defeat. The KKE announced a "temporary cessation" of hostilities in October 1949.

Consequences were severe and lasting:

• Tens of thousands killed; large-scale population displacement, including the controversial evacuation of children (the paidomazoma) to Eastern Bloc states.
• A long period of anti-communist political exclusion in Greece, with the KKE banned until 1974.
• Greece's firm alignment with the West, joining NATO in 1952.
• Deep social cleavages that shaped Greek politics through the 1967–1974 military junta and beyond.
