The National Socialist German Workers' Party, or Nazi Party, was the ruling political party in Germany from 1933 through the end of the decade. Its ideology reflected extreme German nationality and racial purity (in specific, anti-Semitism), and decried communism, democracy, and liberalism. The party's leader was Adolf Hitler.
In the last free election in Weimar Germany in 1933, the Nazis took 44% of the vote. Though not a true majority, this gave the Nazis a two-thirds majority in the German government, allowing them to pass the Enabling Act. This act set up the Nazis as the only legal political party in Germany, and gave Hitler the power to do whatever he wanted.
