What document defines the framework of the U.S. government?

The Constitution is the foundational document that outlines the framework of the United States government. It establishes the structure of government, delineates the powers and responsibilities of the three branches—executive, legislative, and judicial—and embodies the principles of federalism and checks and balances. The Constitution serves as the supreme law of the land, meaning that no law or government action can violate its provisions. Through the amendments, it has also evolved to reflect changes in societal values and the rights of citizens, starting with the first ten amendments, known as the Bill of Rights, which protect individual liberties and rights. Understanding the Constitution is crucial for grasping how the U.S. government operates and its foundational principles.
