During World War II, Nazi Germany undertook the imprisonment and summary execution of many of its own citizens, and citizens of the nations they occupied. One of the groups that came under assault was the European Jewish population. More than six million Jewish people were killed in a systematized genocide. Five million more people died in the same time frame as a result of Nazi persecution. In addition to the Jews, Roma people, homosexuals, political dissidents, Polish people, Slavic people, black people, and many other perceived enemies were imprisoned and killed by the regime.
