Federalists supported ratifying the new Constitution as they felt the Articles of Confederation gave too much power to states and too little to the national government. Antifederalists opposed ratification as they felt it made the national government too strong and states too weak. A key issue in the debate was that the Constitution lacked a Bill of Rights. States began ratifying the Constitution in 1787, with Delaware first and Rhode Island last in 1790. Many states agreed to ratify only if a Bill of Rights was added. James Madison wrote 12 proposed amendments in 1789, with 10 being ratified as the Bill of Rights.
