Nazism (or National Socialism; ) is a set of political beliefs associated with the Nazi Party of Germany. It started in the 1920's, but the Nazi Party gained power in 1933, starting the Third Reich. They lasted in Germany until 1945, at the end of World War II. National Socialism is an extreme right-wing, economically opportunistic ideology that is heavily inspired from the works of Oswald Spengler. The Nazis believed that only the Aryan race was capable of building nations and other races, notably the Jewish race, were agents of the corruptive forces of capitalism and bolshevism, both of which the Nazis opposed. The Nazis blamed the Jewish people for Germany's defeat in World War I. This is known as the Stab in the Back Myth. The Nazis also blamed the Jewish people for rapid inflation and practically every other economic woe facing Germany at the time as a result of their defeat in World War I. For this reason, the Nazis not only viewed the Jewish people as inferior to them, but as oppressors of the Aryan people. The Nazis' tactic of lazily albeit effectively blaming the Jewish people for all of Germany's problems is a propaganda tactic known as scapegoating and was used to justify the great atrocities committed by the Nazis against the Jewish people.
