how many jews were killed by hitler

Approximately six million Jews were killed during the Holocaust, which was orchestrated by Adolf Hitler and the Nazi regime between 1941 and 1945. This genocide was part of a broader campaign of persecution and extermination that targeted various groups, including Romani people, disabled individuals, Polish people, Soviet prisoners of war, communists, homosexuals, and others deemed "undesirable" by the Nazis. The Holocaust remains one of the most horrific events in human history.
