In 1933, The Nazi party came to power in Germany under Adolf Hitler, and immediately began the systematic persecution of Jews. In 1935 the Nuremburg Laws stripped Jews of all civil rights, and through 1945 Nazi Germany annihilated European Jewry by forced removal to concentration camps. Other groups were also persecuted for racial, ethnic or nationalistic reasons. Roma and Sinti, people with mental and physical disabilities, Poles, homosexuals, Jehovah's Witnesses, Soviet prisoners of war, and political dissidents: all suffered grievous oppression or death. Approximately 78% of the European Jewish population was murdered, and estimates of the total number of victims, Jews and others, range from 9 to 11 million.
