Final answer:
An absolute monarchy is characterized by a ruler with complete control, while a constitutional monarchy shares power with other political figures. The divine right principle, associated with absolute monarchy, states that monarchs derive their authority from being chosen by God.
Step-by-step explanation:
An absolute monarchy is characterized by a ruler who holds complete control and is not accountable to any other state authority. In contrast, a constitutional monarchy operates within a framework of a constitution and shares power with other political figures. The divine right principle, associated with absolute monarchy, asserts that monarchs derive their authority from being chosen by God, and it supports their absolute rule.
