When we think of the Holocaust we usually think that Jewish people were the Nazi's only target. There were so many other groups that were targeted as well, like the Soviets, the mentally ill, the deaf, the physically ill, Roman Gypsies, Jehovah Witness', homosexuals, and many more. However everyone, regardless of age or race, was targeted or affected by the Holocaust. All in all, eleven million people were slaughtered during the Holocaust.
