A constitutional monarchy is a form of government where a monarch's powers are limited by a constitution or legislative body, contrasting with an absolute monarchy, where the monarch has uncontrolled authority. In a constitutional monarchy, the constitution outlines the structure of government, ensuring the rule of law and protecting citizens' rights. The monarch typically serves as a ceremonial figurehead, while elected officials hold real political power. This system promotes a balance of power and often provides mechanisms for political accountability, distinguishing it from the unchecked sovereignty in absolute monarchies.
