Other than the Jews, who else were victims of the holocaust?

Homosexuals, gypsies, and people with mental disabilities were all targeted in the Holocaust.

Explanation:

When Hitler came to power, he started passing laws inhibiting the rights of Jews and other minorities. These laws became known as the Nuremberg Race laws. Some of these laws included the forced castration of the "undesirables," or people with mental or physical disabilities.

Other than Jews, the primary victims of the Holocaust were:

LGBTQ individuals, the physically and mentally disabled, gypsies, Poles and other Slavic people, Jehovah's Witnesses, and members of political opposition groups.
