The Federalists supported a strong central government and the ratification of the US Constitution, as expressed through the Federalist Papers authored by Madison, Hamilton, and Jay. The Anti-Federalists opposed increasing federal power and wanted to protect the powers of state governments. They worried the presidency could become a monarchy. The Constitution was ratified after debates between the two sides in states like New York, where Federalist 10 addressed the Anti-Federalists' concerns about factions.
