Nazi crimes against children

Nazi Germany perpetrated various crimes against humanity and war crimes against children, including the killing of children of unwanted or "dangerous" people in accordance with Nazi ideological views, either as part of their idea of racial struggle or as a measure of preventive security. They particularly targeted Jewish children in the Holocaust, but also ethnically Polish children and Romani (also called Gypsy) children and children with mental or physical disabilities.
