A constitutional monarchy is a form of government where a monarch acts as the head of state within the parameters of a constitution, which limits their powers. Unlike absolute monarchies, where the king or queen wields unrestricted authority, constitutional monarchies operate under rule of law and democratic principles. In this system, the parliament or similar legislative body holds significant power, making laws and governing. The monarch often has ceremonial duties, while elected representatives manage day-to-day governance. This balance promotes political stability and respect for democratic values.
