The Holocaust was the mass killing of 6 million Jews that Hitler organized. It was suppose to cleanse the country of Germany but was the worst possible thing to do.
The word Holocaust was used to describe a offering burned on an altar. Now, the word has a horrible meaning: "the mass murder of some 6 million Jews by the German Nazi regime during the Second World War". To Adolf Hitler, Jews were a threat to Germany's "pure" community. During years of Nazi's fighting, the Jews were consistently dying, Hitler’s “final solution”. If you were lucky, the soldiers at one point would be liberated, but lots would die from disease after liberation.
