1. The Warsaw Jewish Ghetto was established in 1940 by the German occupation forces during World War II. It was the largest ghetto in Nazi-occupied Europe, housing over 400,000 Jews. The conditions were overcrowded, unsanitary, and food and medical supplies were scarce. The Jews were forced to wear a Star of David armband and were subjected to humiliating and violent treatment by the German authorities. In 1943, the Warsaw Ghetto Uprising occurred, during which the Jews fought back against the Germans, but were ultimately defeated and forced to evacuate to concentration camps. Today, the Warsaw Jewish Ghetto is a powerful symbol of the atrocities committed during the Holocaust and serves as a memorial to the victims.
