Markos Vafiades (born Jan. 28, 1906, Asia Minor [now in Turkey]—died Feb. 22, 1992, Athens, Greece) was a Greek insurgent, founding member of the Greek Communist Party, and commander of the communist-led Democratic Army in the civil war against the Greek government (1946–49).
Vafiades worked as a labourer in Istanbul and fled to Greece as a refugee in 1923. He became a communist in his teens and fought with the partisans against the Germans during World War II. After the war he remained with the communist guerrilla forces, rising to commander under the title General Markos. In December 1947 he proclaimed a provisional Greek government in northern Greece with himself as prime minister, but it was never internationally recognized, and when nationalist troops crushed the civil war (1949), he was forced into exile. He settled in the Soviet Union, where he clashed with party leadership and was alternately purged (1950), rehabilitated (1956), purged (1964), and restored to party membership (1969). He returned to Greece after a general amnesty was declared (1983), and he was elected to parliament as a supporter of the Panhellenic Socialist Movement (1989).
