For 12 years, from 1933 to 1945 the Holocaust has been in 23 different countries. The Nazi have killed over five million Jews, and most of them were killed in 1942. Some of the Jews who were imprisoned at concentration camps. No one knew what was going on inside of there, and few wanted to find out. So what going on in there you ask, well I`ll tell you what. The Jew were being killed by the hundreds at a time. Auschwitz was on of the larger camps had contained gas chambers. The Jews thought they were going to take a shower, because they did not get to a camp,  so they walked in. But they were wrong, the gas chambers were to kill them,klykon-B was a gas to kill them with. Eventually, crematoria – huge oven designed to burn or cremate hundreds of bodies at once. If the Nazi found out that you were hiding a Jew,you would be shoot in public or sent to a concentration camp as a prisoner. The bodies of the Jews were sold as fertilizer or glue. Adolph Hitler was the leader of the Holocaust, he wanted a master race of people with blond hair and blue eyes. About two-thirds of all the European Jews were killed ruthlessly. By the end of the war Hitler killed himself. That is the inside dirt about the Holocaust. ;p
