A constitution is a system for governance, often
codified as a written document, that establishes the rules and principles of an autonomous political entity. In the case of countries, this term refers specifically to a national constitution defining the fundamental
political principles, and establishing the structure, procedures,
powers and
duties, of a
government. Most national constitutions also guarantee certain
rights to the people. Historically, before the evolution of modern-style, codified national constitutions, the term constitution could be applied to any important
law that governed the functioning of a government.
