Nazism Research StarterA German political movement that advocated racial nationalism (including anti-Semitism), dictatorial government, and expansion into eastern Europe by means of war, Nazism, a contraction of the term “National Socialism,” was a German political movement that emerged in the aftermath of World War I with Adolf Hitler as its leader. From the very start, it espoused ideas that rejected Western values of humanitarianism, rationalism, liberalism, democracy, and socialism in favor of extreme nationalism, racism, and a political system of single-party dictatorship. Nazi policies and practices violated human and civil rights, first in Germany and later in conquered Europe, and resorted to violent power politics in international affairs.
