The foundational principles of a country's government are outlined in a constitution. This essential document delineates the structure of government, the distribution of powers, and the rights of citizens. It serves as the supreme law, guiding the legal and political framework within which a nation operates. By establishing rules for governance, a constitution ensures accountability, protects individual liberties, and provides mechanisms for amendment to adapt to changing societal needs. Thus, it is central to the identity and legitimacy of a nation's political system.
