The Holocaust is the term generally used to describe the killing of approximately six million European Jews during World War II, as part of a program of deliberate extermination planned and executed by the National Socialist German Workers Party in Germany led by Adolf Hitler.
While there were other groups of people killed by the Nazi regime, scholars typically do not include them in the definition of the Holocaust, defining it as the genocide of the Jews, or what the Nazis called the "Final Solution of the Jewish Question." Taking into account all the victims of Nazi persecution, the death toll is estimated at between 9 and 11 million.
