The document summarizes key events and compromises that occurred during the Constitutional Convention in 1787. Delegates from each state met in Philadelphia to revise the Articles of Confederation. They debated plans such as the Virginia Plan, which proposed a strong central government, and the New Jersey Plan, which wanted to keep power with the states. The Great Compromise created a bicameral legislature to balance power between small and large states. The Three-Fifths Compromise counted slaves as three-fifths of a person for representation to balance Northern and Southern state interests. These compromises helped establish the foundation of the US government with three branches and systems of checks and balances.
