Nazism, officially called National Socialism(German: Nationalsozialismus), refers primarily to the ideology and practices of the National Socialist German Workers’ Party under Adolf Hitler; and the policies adopted by the government of Nazi Germany from 1933 to 1945.
Nazism is sometimes considered by scholars to be a form of fascism. While it incorporated elements from both political wings, it formed most of its alliances on the political right. The Nazis were one of several historical groups that used the term National Socialism to describe themselves, and in the 1920s they became the largest such group. The Nazi Party formulated its program in the 25 point National Socialist Program. Among the key elements of Nazism were anti-parliamentarism, Pan-Germanism, racism, collectivism, eugenics, antisemitism, anti-communism, totalitarianism and opposition to economic liberalism and political liberalism.
Nazism was not a monolithic movement, but rather a (mainly German) combination of various ideologies and groups such as Strasserism and Black Front, sparked by anger at the Treaty of Versailles and what was considered to have been a Jewish/communist conspiracy to humiliate Germany at the end of the World War I. This Nazi party came to power in 1933 in the aftermath of the Great Depression, seeking a Third Way "managed economy". Nazi rule ended in 1945 when the Allied Powers took over Germany.
