Nobles in ancient Greek city-states had overthrown most of the monarchs by 650 B.C.E.

This transformation marked the shift from monarchies to oligarchies as the power began to concentrate in the hands of the aristocrats. The changes were stimulated by a series of social, economic, and political developments. Increased wealth among the nobility and widespread dissatisfaction with monarchic rule fueled the demand for greater political participation by the aristocrats. As a result, many city-states transitioned into systems where the elite had significant control, leading to the establishment of independent governing bodies and increased civic engagement among citizens—a crucial step in the evolution of democratic principles in classical Greece.
