Who government structure and powers under the Articles of Confederation differed from the government under the U.S. Constitution. How did the role of the government expand under the U.S. Constitution?

Under the Articles of Confederation, the government had a weak central authority with limited powers, primarily focusing on foreign affairs and defense, while most powers rested with the individual states. The U.S. Constitution established a stronger federal government with separate branches—executive, legislative, and judicial—allowing for a system of checks and balances. This expansion of power enabled the federal government to levy taxes, regulate commerce, and enforce laws, addressing the inefficiencies and challenges faced under the Articles. Consequently, the Constitution provided a more cohesive and effective framework for governance in the newly formed nation.
