Adolf Hitler, the Leader of the German National Socialist (Nazi) party, preached a racist brand of fascism. Hitler promised to overturn the Versailles Treaty, restore German wealth & glory and secure additional Lebensraum ("living space") for the German people, who he contended deserve more as members of a superior race. In 1933 Hitler became the German Chancellor, and in a series of subsequent moves established himself as dictator. In 1941 the Nazi regime unleashed a war of extermination against Slavs, Jews, and other elements deemed inferior by Hitler's ideology.
