Yes, it is possible for a republic or a constitutional monarchy to be authoritarian. Authoritarianism refers to a form of government in which power is concentrated in the hands of a small group or individual who exercises strict control over society. This can occur in any type of political system, including republics and constitutional monarchies, if the rulers or governing officials suppress political opposition, limit civil liberties, and exert control over all aspects of society. Examples of authoritarian republics and constitutional monarchies include countries like China, Russia, Saudi Arabia, and North Korea.
