Which document replaced the Articles of Confederation?

The document that replaced the Articles of Confederation is the Constitution. The Articles of Confederation, which were enacted during the Revolutionary War, created a loose confederation of states with a weak central government that struggled to address various issues, including economic instability and interstate disputes. As a result, the Constitutional Convention was held in 1787 to address these shortcomings. The outcome was the United States Constitution, which established a stronger federal government with separate branches (executive, legislative, and judicial) and a system of checks and balances. This marked a significant change in the governance of the United States, moving from a system that prioritized state sovereignty to one that balanced power between state and federal authorities. The ratification of the Constitution ultimately led to its acceptance as the supreme law of the land, replacing the Articles of Confederation.
