The Holocaust began as Nazis sought to establish a racial order, deeming Aryans the master race while targeting Jews and other groups as inferior. The systematic persecution escalated with the implementation of the Nuremberg Laws and violent events like Kristallnacht, leading to the establishment of ghettos and eventually extermination camps for mass killings under the 'final solution.' Approximately six million European Jews were murdered, with survivors escaping through the assistance of non-Jewish individuals.
