The Holocaust was the persecution and murder of millions of Jews, Romani people, political dissidents and homosexuals by the German Nazi regime from 1933-1945.

Anti-Semitism, sometimes called history’s oldest hatred, is hostility or prejudice against Jewish people. The Nazi Holocaust is history’s most extreme example of anti-Semitism. Anti-Semitism did not begin with Adolf Hitler—Anti-Semitic attitudes date back to ancient times.
