A constitutional monarchy differs from an absolute monarchy primarily in the distribution of power. In a constitutional monarchy, there is a constitution that outlines the limits of the monarch's authority, often sharing power with an elected parliament or government. The monarch's role may be largely ceremonial, with real political power resting in the hands of representatives elected by the people. Conversely, in an absolute monarchy, the monarch holds unlimited power and governs without any legal limitations or democratic constraints. This distinction shapes the governance and political rights of citizens in these systems.
