Which 1787 document established the framework of the federal government celebrated during America250?

The United States Constitution established the framework of the federal government celebrated during America250.

The Constitution was drafted at the Philadelphia Convention in 1787 after delegates concluded that the Articles of Confederation had created a national government that was too weak to address major problems. The new document created three branches: legislative, executive, and judicial.

It also established a system of checks and balances and divided authority between the federal government and the states. The Constitution was signed on September 17, 1787, and took effect after ratification by the required states in 1788.

The Articles of Confederation preceded the Constitution, while the Bill of Rights was added later as the first ten amendments. The Federalist Papers were essays supporting ratification, not the governing document itself.
