Berlin - It was one of the biggest thefts in history - the forced transfer of Jewish-owned businesses, homes and art collections to German "Aryan" ownership.
Long before the Kristallnacht pogrom of November 9, 1938, the Nazis systemically began seizing possessions of Jews living in Germany, under an official policy known as Aryanization.
After the start of World War II in September 1939, the Germans continued the looting in Eastern Europe, helped by a huge apparatus which administered the stolen items.
The main beneficiaries were the Nazis themselves, their supporters, art dealers and museums.
