@farmerman,
During the Second World War, the
Reichsleiter Rosenberg Taskforce was a Nazi organisation, which looted art in France, the Benelux countries, Poland, the Baltic States, Greece, Italy and on the territory of the Soviet Union in the Reichskommissariat Ostland and Reichskommissariat Ukraine.
The
Sonderkommando Künsberg (aka
Group Künsberg) did the same in Yugoslavia, Greece, and Russia.
The
Ahnenerbe ("
Inheritance of the Forefathers") gave the pseudo-scientic reasons for the looting, 'researching' the supposed archaeological and cultural history of the hypothesized "Aryan race."
