The United States Constitution stands as the supreme law of the United States and the cornerstone of its democratic system. Ratified in 1788, it established the framework of the federal government, defined the balance of power between its branches, and secured the rights and liberties of its people. Through its enduring structure and the addition of amendments—beginning with the Bill of Rights—the Constitution has adapted to the evolving needs of the nation while preserving the principles of liberty, justice, and representative government. This page explores its origins, structure, and the amendments that have shaped the course of American history.
