George Washington chaired the Constitutional Convention and supported ratification. James Madison was known as the "Father of the Constitution" and also supported ratification. He authored the Virginia Plan and later drafted much of the Bill of Rights. The ratification process established states would hold conventions to accept or reject the Constitution, requiring nine approvals. Debates occurred between Federalists, who favored a strong national government, and Anti-Federalists, who wanted protected individual rights and distrusted centralized power. In response, Madison drafted the Bill of Rights guaranteeing citizen protections, securing ratification.
