The primary purpose of a constitution in a political context is to outline the fundamental principles and framework of government. It serves to establish the structure, functions, and limits of governmental power, ensuring that no branch exceeds its authority. Additionally, a constitution enshrines the rights and freedoms of individuals, providing a safeguard against tyranny. By codifying the rule of law, constitutions promote stability and predictability in governance, allowing citizens to understand their rights and responsibilities. Ultimately, a constitution acts as a guiding document that shapes the political culture and ideologies of a nation.
