The Holocaust was the systematic persecution and murder of approximately six million Jews by the Nazi regime between 1933-1945. The Nazis believed Germans were racially superior and targeted Jews, Roma, Slavs, disabled people, and others they deemed racially inferior for persecution and genocide. Over two-thirds of Europe's Jewish population was murdered as part of the Nazis' "Final Solution." In addition to Jews, the Nazis also murdered over 200,000 Roma people, 200,000 disabled patients, and over one million children.
