The Holocaust was the state-sponsored, systematic persecution, and annihilation of European Jewry by Nazi Germany and its collaborators, between 1933 and 1945.
What is Antisemitism?
The prejudice against or hatred of Jews, the Holocaust was the most extreme example of antisemitism. World War 1 intensified antisemitism and racist antisemitism flourished in Nazi Germany. Even after the defeat of Nazi's in World War 2 antisemitism is still a problem in many parts of the world today.
Nazi Germany established about 20,000 camps between 1933 and 1945. These camps were used for forced-labor, transportation of items or things, and killing centers. They had a range from German Communists, Socialists, Social Democrats, Roma, Jehovah's Witnesses, homosexuals, and persons accused for asocial or deviant behavior, as prisoners in their camps.
In 1939 Nazi's made forced-labor and prisoners-of-war-camps after the invasion of Poland, followed by the first killing center in 1941.
America and the Holocaust
During World War 2 the U.S. Government didn't think saving Jews were their main priority at the moment. Though in 1939 and 1940 more than half of all immigrants in the U.S. were Jewish. When the United States finally entered the war in 1941, when the Nazi's were going to murder the Jews of Europe, the immigrants slowly came to a stop. The U.S sent out a declaration that the Nazi's will be punished for their crimes.
