Art theft and looting during World War II

Art theft and looting occurred on massive scale during World War II. It originated with the policies of the Axis countries, primarily Nazi Germany and Japan, which systematically looted occupied territories. Near the end of the war the Soviet Union, in turn, began looting reclaimed and occupied territories.

For organized looting, see:
 * art theft and looting by Nazi Germany
 * art theft and looting by Japan
 * art theft and looting by the Soviet Union

On a smaller scale, art was stolen by individuals from various countries, taking opportunity of the chaotic war conditions. For example, see:
 * Theft of medieval art from Quedlinburg
