Communist Party of Greece (Greek: Κομμουνιστικό Κόμμα Ελλάδας; Kommounistikó Kómma Elládas, KKE) is a political organisation in Greece that follows a Marxist–Leninist programme. Founded in 1918 as the Socialist Labour Party of Greece, it adopted the name KKE in November 1924 and is often cited as the oldest continuously existing modern political party in the country.

Early years and interwar period

The party emerged during the upheavals of the immediate post‑World War I era and soon established itself as a distinct force on the Greek left. Throughout the 1920s and 1930s it experienced internal debates and state repression, as did many radical organisations across Europe during that period.

World War II and the Resistance

During the Axis occupation of Greece (1941–1944) members of the party played a prominent role in the anti‑occupation struggle, participating in broad resistance networks and mass organisations. Its affiliated formations became among the largest organised resistance groups in the country, and party membership reached its highest levels in the mid‑1940s.

Civil War, proscription and return to legality

After the liberation of Greece, the political tensions between the left and the government contributed to the outbreak of the Greek Civil War (1946–1949). The party and its allies were defeated, and in the decades that followed the KKE was banned and forced to operate clandestinely or in exile. Legalisation did not occur until the period after the fall of the military junta, with formal restoration of full political rights in 1974.

Electoral politics since the 1970s

Once legal, the party resumed normal political activity, contesting national and local elections and maintaining an organised presence in trade unions and social movements. In the turbulent year of 1989 the KKE obtained a notable share of the vote—more than 13% in national elections—and was an influential parliamentary actor during a period of coalition building and short‑lived governments.

Organisation and contemporary role

Today the KKE remains an active force in Greek politics. It publishes newspapers and political literature, runs local branches across the country, and continues to present candidates for parliamentary and municipal elections. While its share of the vote has varied, the party retains a structured organisation and a defined ideological profile.
