With the Soviet Union agreeing not to fight and to partition Poland, the German army could quickly turn its sights on the rest of Europe. In April 1940 the Germans invaded Denmark and Norway. One month later, on May 10, 1940, the Germans launched an invasion of Holland, Belgium, Luxembourg and France. Jews from those countries, as well German Jews who had sought refuge there -- such as the family of Anne Frank who had come from Frankfurt, Germany to Amsterdam, Holland in 1933 – were now trapped by the Nazis and subject to severe anti-Semitic restrictions. The Nazis then began the systematic capture and deportation of all Jews to ghettos, transit camps and ultimately to death camps that were built in the East.
