World War II evacuation and expulsion

Mass evacuation, forced displacement, expulsion, and deportation of millions of people took place across most countries involved in World War II.

The Second World War caused the movement of the largest number of people in the shortest period of time in history.

[1] A number of these phenomena were categorised as violations of fundamental human values and norms by the Nuremberg Tribunal after the war ended.

The mass movement of people – most of them refugees – had either been caused by the hostilities, or enforced by the former Axis and the Allied powers based on ideologies of race and ethnicity, culminating in the postwar border changes enacted by international settlements.

The Holocaust also involved deportations and expulsions of Jews preliminary to the subsequent genocide perpetrated by Nazi Germany under the auspices of Aktion Reinhard.
