From Wikipedia:
Fascism /ˈfæʃɪzəm/ is a form of radical authoritarian nationalism[1][2] that came to prominence in early 20th-century Europe. The first fascist movements emerged in Italy during World War I, before it spread to other European countries. Opposed to liberalism, Marxism, and anarchism, fascism is usually placed on the far-right within the traditional left–right spectrum.[3][4]
