Rival externally-backed ruling class factions tore Greece apart in 1920

Evidence

In 1920, Greece was torn between two ruling class factions. On the one hand the supporters of the deposed King Constantine, who leaned towards Germany. On the other the “liberals” headed by Venizelos, supported by the British. After several alternations in power, an attempt was made to assassinate Venizelos— who was Prime Minister at the time in August 1920, and its failure was followed by savage reprisals. Among those massacred was the royalist ex-minister Dragoumis. — Antonio Gramsci, Selections from the Prison Notebooks, 2249
