Jews, Slavs, Gypsies, political prisoners and many other groups considered less human, were sent to these camps and often used as slave labor or murdered outright. The most common method for killing the Jews was the gas chamber, where hundreds at a time would be sent for mass extermination, including children. Their bodies were then burned in crematoriums. All total, the Germans murdered some 6 million Jews during the war and 6 million "others," including Gypsies and Slavs. The extermination of the Jews was known in Germany during the war as "The Final Solution." We know it today as the Holocaust.
