The main purpose of a constitution in a democratic society is to establish the fundamental framework for governance and protect individual rights. It outlines the structure of government, delineates powers and responsibilities, and sets forth processes for policymaking. Constitutions serve to limit government authority, ensuring that power is not concentrated and that citizens' rights are safeguarded. By providing a clear legal framework, constitutions promote stability, accountability, and adherence to the rule of law. Furthermore, they reflect societal values and aspirations, thereby playing a significant role in fostering national identity and unity.
