what is the purpose of all constitutions?

The purpose of all constitutions is to establish the fundamental principles, laws, and structures of a government, as well as protect and guarantee the rights and freedoms of its citizens. Constitutions serve as the supreme law of the land and provide a framework for how government institutions should operate, the limits of their powers, and the rights and responsibilities of individuals within the society. Constitutions also help maintain stability, order, and accountability within a government system.
