The Constitutional Convention was held in Philadelphia in 1787 with 55 delegates from 12 states debating how to structure the new federal government. They proposed several plans, including the Virginia Plan which called for a strong central government with three branches, and the New Jersey Plan which proposed equal state representation in Congress. The delegates ultimately reached compromises, including the Great Compromise which created a bicameral legislature with proportional representation in the House and equal representation in the Senate. They also agreed to count enslaved people as 3/5 of a person for representation and not banning the international slave trade for 20 years.
