When Athens turned into a battlefield: The violent climax of Greece's National Schism

History · Published 3 October 2026 Swipe more like this →

In short: In December 1916, Allied marines landed in Athens to seize war material, only to face unexpected, organized resistance from the Greek military. This clash, known as the Noemvriana, triggered days of riots and cemented a deep, bitter divide between royalists and supporters of the pro-Allied government in Thessaloniki.

The Noemvriana emerged from a fundamental disagreement over Greece's role in World War I. King Constantine I, influenced by his Prussian ties and a desire for neutrality, clashed with Prime Minister Eleftherios Venizelos, who sought to join the Allies to secure territorial gains. This tension reached a breaking point in May 1916 when the Greek government surrendered Fort Roupel to German-Bulgarian forces, fueling Allied fears of a secret pact between Athens and the Central Powers.

By late 1916, Greece was effectively split. Venizelos had established a provisional government in Thessaloniki, while royalist forces controlled Athens. The Allies, led by Admiral Louis Dartige du Fournet, demanded the surrender of Greek mountain artillery to compensate for equipment lost at Roupel. Underestimating Greek resolve, Allied forces landed in Athens on 1 December 1916. They were met by over 20,000 royalist troops and militia, leading to a fierce armed confrontation that resulted in nearly 200 Allied casualties and dozens of Greek losses.

The aftermath was marked by brutal reprisals. Royalist mobs targeted Venizelos's supporters, and the Allies imposed a naval blockade that caused widespread starvation in Athens. The conflict only ended in June 1917, when King Constantine abdicated in favor of his son, Alexander. This allowed Greece to unify under Venizelos and eventually contribute to the Allied success in the Balkans, helping to drive the Central Powers from the region and restore Serbian sovereignty.
