After World War I Greek troops landed at Smyrna and advanced inland during the Greco-Turkish War (1919-1922). After the battle at Bergama retreating Greek army units managed to enter Menemen as part of the Greek occupation zone of Smyrna. However, they had to retreat temporarily from the town after fierce Turkish resistance during which excesses were committed by both sides. The subsequent massacre, on 17 June 1919, due to these developments, resulted in 200 Turkish civilians being killed and 200 others being wounded by the Greeks, while Turkish sources themselves claim 1000 dead. The events were protested by the Ottoman Sheikhulislam. The Greek military claimed that they were attacked in the town, on the other hand an Allied commission, after investigation, believed that their statements was not correct and found the Greeks alone responsible for the bloodshed, however they agreed that the massacre was not organized by the Greek Command, but was as a result of the panic and anger of the young Greek troops who were still affected by the Bergama events and whom their officers were not able to calm.
