fascist
An ultra-nationalist and authoritarian ideology first popularized by Benito Mussolini in Italy around the 1920s, and then by Adolf Hitler in Germany during the 1930s; German fascism is better known as Nazism.
Fascists usually promote national and (occasionally) racial supremacy over other countries, are very big believers in "social Darwinism", and seek to maintain or expand the country for the benefit of the "master race" at the other's expense.
