What other groups were targeted by the Holocaust?

In addition to Jews, the Holocaust targeted several other groups, including Romani people (Gypsies), disabled individuals, Polish people, Soviet prisoners of war, and various political dissidents, such as communists and socialists. Jehovah's Witnesses were also persecuted for their religious beliefs. The Nazi regime aimed to eliminate those they considered "racially inferior" or politically threatening, leading to the systematic extermination of millions.
