The Asia Minor Catastrophe refers to the mass population exchange and violence that occurred in the aftermath of World War I, particularly between 1919 and 1922. It involved the forced migration of Greek populations from Asia Minor to Greece and the expulsion of Turkish populations from Greece to Turkey. This event was part of the larger conflict between the Greek and Turkish national movements. The catastrophe was marked by significant loss of life, destruction of communities, and widespread suffering. The culmination of these events was the Great Fire of Smyrna in 1922, which devastated the city and led to further displacement. The aftermath reshaped the demographics of the region and had lasting impacts on Greek-Turkish relations.
