The Holocaust was caused by Hitler’s need to blame. Germany needed an enemy that could be blamed for everything that had happened and the Jews were a perfect target. Jews have no homeland and they have been picked on as the outcast through history. The Holocaust happened because Hitler wanted to get reed of the impure race of Jews. He also thought they were taking all the jobs and were plotting a communist up rise. So the only way to fix this problem was to start a system of eradication of Jews. This was the cause of the Holocaust.
