Nazism was primarily practiced in Germany under the leadership of Adolf Hitler. Nazism is a political ideology that is characterized by totalitarianism, nationalism, racism, and anti-Semitism. The Nazi Party came to power in Germany in 1933, and under Hitler's leadership, they began implementing their fascist policies, which included the persecution and murder of millions of Jews, as well as other minority groups, during the Holocaust. While fascist and authoritarian regimes did exist in other countries during the 20th century, Nazism as an ideology and a political movement was uniquely associated with Germany under Adolf Hitler's leadership. Therefore, Britain under Churchill, the United States under Woodrow Wilson, and Spain under General Franco did not practice Nazism as their primary political ideology.
