Constitution

A constitution is the aggregate of fundamental principles or established precedents that constitute the legal basis of a polity, organization, or entity, determining how it is governed. Constitutions can be written or unwritten, with written constitutions often being codified in a single document, while unwritten constitutions are established through fundamental acts, court cases, and treaties. Constitutions can apply to various levels of organizations, including sovereign countries, companies, and international organizations, and define the principles, procedures, and powers of the entity. They often act as limiters of state power, establishing fundamental rights and requiring consensus or supermajority for changes.learn more on wikipedia
