the holocaust was a horible event where the Nazi's killed millions of jewish people. It all started in 1933 when Adolf Hitler and the Nazi's came to power. They thought that the german race was supirior and that the jews where a alien threat and should be exterminated. I wasn't only jews that the Nazi's were killing. They also thought that homosexuals, gypsies, and disabled people shouldn't live because they had different believes than the Nazi's. Over all around six million jews and around five hundred thousand other people died. These people were killed in the largest genocide in human history.
