The document summarizes the establishment and conditions of the Warsaw Ghetto during World War 2. It was established in 1940 by the German governor and forced over 400,000 Jewish people from Warsaw and surrounding areas into a walled 2.4% section of the city. Conditions were difficult, with the ghetto split into a smaller "rich" section and larger area. The Nazis closed off the ghetto from the outside world in 1940. Prior to the war, Warsaw had a large Jewish population that made up 30% of the city.
