National Socialism, a subset of fascism, is a political philosophy that is most notorious for having been the party ideology of Adolf Hitler's Nazis. National socialism combined an appeal to workers and the middle classes, radical anti-capitalism (in its movement stage) together with political opportunism, anti-Marxist agitation and violence, and fierce ethnic nationalism, anti-Semitism and racism. Upon achieving state power, the doctrine of National Socialism has proven to be genocidal, totalitarian, and imperialist. National Socialism claims to resolve the contradictions between capital and labor, often through a "third way".
