The Constitutional Convention was called in 1787 in Philadelphia to address weaknesses in the Articles of Confederation, including the inability to levy taxes or regulate commerce. Delegates debated plans like the Virginia Plan, which proposed a strong federal government with two legislative chambers, and the New Jersey Plan, which proposed a weaker federal government with one chamber. A key compromise was the Three-Fifths Compromise to determine representation of slaves in the population. The Convention ultimately produced the U.S. Constitution to replace the Articles of Confederation.
