Anarchism in Greece traces its roots to ancient Greece but was formed as a political movement during the 19th century. It was in the ancient era that the first libertarian thoughts appeared when philosophers based on rationality questioned the fundamentals of tradition. Modern anarchism in Greece emerged in the 19th century, heavily influenced by the contemporary European classical anarchism. Because of the Bolshevik success in the Russian Revolution of 1917 and the rise of the Communist Party, anarchism faded after the first decades of the 20th century. The collapse of the military Junta put an end to the monopoly of the political power from the Right, whereas the dissolution of the Soviet Union diminished the allure of the Communist Party of Greece allowing anarchist groups to gain pace in Athens and other cities.
