The Goudi coup was a military coup d'état that took place in Greece on the night of 28 August [O.S. 15 August] 1909, starting at the barracks in Goudi, a neighborhood on the eastern outskirts of Athens. The coup was a pivotal event in modern Greek history, as it led to the arrival of Eleftherios Venizelos in Greece and his eventual appointment as prime minister. At one stroke, this put an end to the old political system, and ushered in a new period. Henceforth and for several decades, Greek political life was dominated by two opposing forces: liberal, republican Venizelism and conservative, monarchist anti-Venizelism.
