What is a primary purpose of a written constitution?

A primary purpose of a written constitution is to ensure a limited government. This involves establishing the fundamental principles and guidelines that govern a state or nation, setting boundaries on government power, and protecting the rights of individuals. By defining the structure of government, the roles of different branches, and the relationship between the government and the governed, a constitution seeks to prevent the arbitrary use of power and maintain a system of checks and balances. This limitation is vital for maintaining democracy and the rule of law, as it creates an environment where governmental authority is derived from the consent of the governed and is bound by law rather than individual whims.

Other options reflect ideas that are not consistent with the foundational role of a constitution. For instance, a constitution does not primarily exist to outline military responsibilities or to provide a framework for absolute leadership, as these concepts often suggest a concentration of power contrary to the principle of limited government. Similarly, a constitution is generally not designed to allow for rapid changes in governance, as it typically seeks stability and continuity in the governing framework to protect citizens' rights and ensure orderly governance.
