The origin of the "Final Solution," the Nazi plan to exterminate the Jewish people, remains uncertain. What is clear is that the genocide of the Jews was the culmination of a decade of Nazi policy, under the rule of Adolf Hitler. The "Final Solution" was implemented in stages. After the June 1933 Nazi party rise to power, state-enforced racism resulted in anti-Jewish legislation, boycotts, "Aryanization," and finally the "Night of Broken Glass" pogrom, all of which aimed to remove the Jews from German society. After the beginning of World War II, anti-Jewish policy evolved into a comprehensive plan to concentrate and eventually annihilate European Jewry.
