The Rejection of Absolutism refers to the widespread pushback against the concentration of power in the hands of monarchs during the 17th and 18th centuries, characterized by demands for greater political representation and individual rights. This movement arose as societies began to value Enlightenment ideals, such as reason, liberty, and democracy, leading to challenges against the authority of absolute rulers. It significantly shaped the political landscape of Europe as it paved the way for revolutions and constitutional changes.
