A constitutional monarchy is defined by the existence of a constitution that limits the powers of the monarch and outlines the framework of governance, often ensuring democratic principles. In contrast, an absolute monarchy grants the monarch nearly unchecked authority, with little to no constitutional limitations. In a constitutional monarchy, the monarch's role is largely ceremonial, while elected officials or a parliamentary system manage governance. This distinction affects the political stability and citizen rights within a nation, as constitutional monarchies tend to facilitate greater political representation and civil liberties compared to their absolute counterparts.
