Chauvinism

Wikimedia Commons has media related to Chauvinism.

Chauvinism, in its original meaning, is a form of extreme patriotism and nationalism, and a belligerent belief in national superiority and glory. By extension, it has come to include an extreme and unreasoning partisanship on behalf of any group to which one belongs, especially when the partisanship includes malice and hatred towards rival groups. Jingoism is the British parallel form of this French word, but its meaning has not expanded beyond nationalism in the same way that the word chauvinism has.
