What happened
The uneasy wartime alliance among Greek resistance factions collapsed after liberation in 1944. By 1946, the country was fighting a second war, this one between the British- and later American-backed Greek government and the communist-led Democratic Army of Greece (DSE), successor to the wartime ELAS. The conflict lasted three years, with American advisors and material support helping the government forces after 1948; a decisive break came when Yugoslavia's Tito, in conflict with Stalin, cut off support for the Greek communists in July 1949. Government forces destroyed the remaining communist stronghold in the mountains of Grammos and Vitsi that August, ending the war. Death toll estimates vary by source: one account puts total deaths at around 158,000, while another places the toll at well over 100,000 and possibly close to 150,000; roughly a million people were left homeless, and an estimated 28,000 children were removed from the conflict zones.
Why it matters
The Greek Civil War is often described as the first proxy conflict of the Cold War, with the United States' Truman Doctrine, announced in 1947 partly in response to the Greek crisis, marking the start of a sustained American policy of containing communism through direct aid to threatened governments. The war left Greece politically polarized for decades and set the pattern of foreign, especially American, involvement in Greek internal politics that would recur during the 1967 military coup.
How we know
Casualty figures and the war's course are documented by institutional military history sources, though total death toll estimates vary meaningfully between sources, from just over 100,000 to as high as 158,000, reflecting the difficulty of counting civilian deaths from violence, disease, and displacement in a three-year internal conflict.
