Which document established the framework for the U.S. government?

The Constitution established the framework for the U.S. government by outlining the structure and functions of the government, the relationships between the different branches, and the rights of the citizens. It was drafted in 1787 and replaced the Articles of Confederation, which had created a weak central government that struggled to effectively govern. The Constitution delineates the powers of the legislative, executive, and judicial branches, ensuring a system of checks and balances that is central to American democracy.

In addition to this structure, the Constitution includes the Bill of Rights, which protects individual liberties and limits government power. This foundational document has served as a lasting guide for the operation of the U.S. government and has been amended over time to adapt to changing societal needs while maintaining its fundamental principles.
