Fascism ( FASH-iz-əm) is a far-right, authoritarian, and ultranationalist political ideology and movement that rose to prominence in early-20th-century Europe. Fascism is characterized by support for a dictatorial leader, centralized autocracy, militarism, forcible suppression of opposition, belief in a natural social hierarchy, subordination of individual interests for the perceived interest of the nation or race, and strong regimentation of society and the economy. Opposed to communism, democracy, liberalism, pluralism, and socialism, fascism is at the far-right of the traditional left–right spectrum.
The first fascist movements emerged in Italy during World War I before spreading to other European countries, most notably Germany. Fascism also had adherents outside of Europe. Fascists saw World War I as a revolution that brought massive changes to the nature of war, society, the state, and technology. The advent of total war and the mass mobilization of society erased the distinction between civilians and combatants. A military citizenship arose, in which all citizens were involved with the military in some manner. The war resulted in the rise of a powerful state capable of mobilizing millions of people to serve on the front lines, providing logistics to support them, and having unprecedented authority to intervene in the lives of citizens.
