The Holocaust is the term used to describe the genocide of approximately six million European Jews during World War II, a program of systematic state-sponsored extermination by Nazi Germany, under Adolph Hitler. An additional five million non-Jewish victims perished at the hands of the Nazi regime. These included LGBTQ individuals, the physically and mentally disabled, Roma (gypsies), Poles and other Slavic peoples, Jehovah’s Witnesses, and members of political opposition groups.
