Fascism is an ultranationalist, authoritarian political ideology that glorifies the nation-state, a strong central leader (dictator), and national unity above individual rights, suppressing opposition through force, militarism, and social/economic control, fundamentally rejecting democracy, liberalism, and communism. It emphasizes a powerful, centralized state, extreme nationalism, and often racial purity, promising national rebirth through disciplined, often violent, action, and relies heavily on propaganda and mass rallies to mobilize support.
