The Constitution emerged from a tumultuous period, replacing the weak Articles of Confederation. It established core principles like separation of powers, checks and balances, and federalism, shaping the U.S. government's structure and function.

Key compromises during the Constitutional Convention addressed representation, slavery, and presidential selection. The amendment process allowed for changes, including the Bill of Rights, which protected individual liberties and addressed Anti-Federalist concerns about federal power.
