The Constitutional Convention was held in 1787 to address weaknesses in the Articles of Confederation, including that the federal government was too weak and amendments required unanimous approval. Key debates included the Virginia Plan supported by large states versus the New Jersey Plan backed by small states, which was resolved by the Great Compromise creating a bicameral legislature. The 3/5 Compromise also addressed representation of slaves. Key figures included Washington, Madison, Hamilton, and others who helped shape the new Constitution and federal system of government.
