Foundational documents are key texts that establish the principles and framework of a government or organization. In the context of the United States, important examples include the Declaration of Independence, the U.S. Constitution, and the Bill of Rights. These documents outline the rights of citizens, the structure of government, and the rule of law. These texts serve as a reference point for legal and political discussions, guiding the interpretation of laws and policies. They are essential for understanding the values and beliefs that shape a society, influencing everything from governance to individual rights and responsibilities.
