The U.S. Constitutional Convention of 1787 was convened primarily because the Articles of Confederation—the nation's first governing document—had proven unworkable.12

While the convention was ostensibly called to amend the Articles, the delegates ultimately discarded them to create a stronger central government. The Articles had left the national government without essential powers, such as the ability to levy direct taxation or regulate interstate commerce. This lack of authority, combined with severe economic instability and civil unrest like Shays’s Rebellion, highlighted the urgent need for a more effective federal structure.13

The framers sought to establish a system that balanced authority with individual liberty through separation of powers and checks and balances. Through intense political compromise, including the Great Compromise, they developed a new framework that defined the powers of the executive, legislative, and judicial branches, establishing the Constitution as the supreme law of the land.13
