A political system serves several primary functions, including governance, resource allocation, and the establishment of societal norms. It regulates interactions among people and institutions, providing a framework for conflict resolution and decision-making. Effective political systems also ensure that citizens' needs are met, providing public goods and services. Additionally, they promote civic participation and representation, enabling a system of checks and balances that upholds democratic principles. By fulfilling these functions, political systems contribute to societal stability and progress.
