The famous document that begins with "We the People" is the United States Constitution. Ratified in 1788, the Constitution serves as the foundational legal document of the U.S., outlining the framework of government, the separation of powers, and the rights of citizens. The phrase "We the People" emphasizes the idea that the government's authority derives from the consent of the governed. The Constitution also includes the Bill of Rights, which guarantees individual liberties and protections. This document has undergone amendments over the years and remains a symbol of democracy, governance, and the rule of law in the United States.
