Which document begins with “We the People” and serves as the supreme law of the United States?

The Constitution of the United States begins with “We the People” and serves as the country’s supreme law.

The document was drafted at the Constitutional Convention in Philadelphia in 1787. It replaced the weaker Articles of Confederation, which had created the first national government after independence but gave Congress limited powers.

The Constitution established the federal government’s three branches: Congress makes laws, the president enforces laws, and the federal courts interpret laws. It also defines relationships between the national government and the states.

The Constitution was signed on September 17, 1787, and took effect in 1789 after ratification by the required number of states. The Bill of Rights is not the whole Constitution; it is the collective name for the first ten amendments, ratified in 1791.
