The constitution serves as the supreme law in most countries, establishing the foundational principles and frameworks of governance. It compacts the roles of the government, demarcates the separation of powers, and enshrines the rights of citizens. The constitution is crucial for maintaining a system of rule of law, providing mechanisms for amendment and judicial review, thus enabling adaptations over time. Furthermore, it serves as a symbol of national identity and unity, representing the collective values and aspirations of a society while guiding its political and legal processes.
