The political ideology characterized by extreme nationalism and authoritarian governance is often referred to as fascism. Fascism promotes the idea of a strong centralized state led by a dictatorial leader, emphasizing unity, loyalty, and often militarism. It rejects democratic processes and promotes a singular national identity, often at the expense of minority rights and freedoms. Fascism has historically been associated with oppressive regimes that suppress dissent and utilize propaganda to maintain control over the populace.
