Which document served as the foundation for the U.S. Constitution?

The Articles of Confederation served as the foundation for the U.S. Constitution because it was the first governing document of the United States and laid the groundwork for federal authority. Established in 1781, the Articles created a loose confederation among the states, emphasizing state sovereignty and limiting the powers of the central government. However, as the shortcomings of the Articles became evident—such as the lack of a strong federal government to regulate commerce, levy taxes, or enforce laws—delegates convened to address these issues, ultimately leading to the drafting of the U.S. Constitution in 1787. The Constitution aimed to create a stronger, more effective federal system while addressing the weaknesses highlighted by the experience under the Articles. This transition marked a crucial evolution in American governance, as the Constitution established a framework for federal power and balance among branches of government that is still in use today.
