Constitutional agreements are formal arrangements that outline the fundamental principles and rules governing a political entity, such as a country or state. These agreements serve as the foundation for the legal and political framework, ensuring that the rights and responsibilities of citizens and government are clearly defined. They often include provisions for the separation of powers, individual rights, and the process for amending the constitution. These agreements can take various forms, including written documents like the United States Constitution or unwritten conventions, as seen in the United Kingdom. They are essential for maintaining order, stability, and the rule of law within a society, guiding how laws are created and enforced.
