The Final Solution to the Jewish Question (Endlösung der Judenfrage) was the official code name for the murder of all Jews during World War II.
The deliberate and systematic genocide across German-occupied Europe was formulated in procedural and geopolitical terms by Nazi leadership in January 1942 at the Wannsee Conference near Berlin and took action becoming the Holocaust, the extermination of approximately two-thirds of the Jewish population of Europe.
