Political norms develop over time, shaped by evolving societal values, historical events, and institutional practices. These norms define acceptable behavior among political actors and guide interactions within the political system. Major events—such as crises, reforms, or social movements—can accelerate shifts in norms, challenging established patterns and prompting new conventions. Furthermore, public opinion plays a critical role in influencing norms, as societal expectations can lead to demands for accountability, transparency, and ethical governance. Understanding the development of these norms is crucial for recognizing their impact on political culture and behavior.
