Was James Monroe Patrick Henry and George Mason leaders of anti federalists or federalists?

James Monroe was a Federalist early in his career but later aligned more with the Democratic-Republican Party, which opposed many Federalist policies. Patrick Henry and George Mason were prominent Anti-Federalists, opposing the Constitution's ratification due to concerns over centralized power and the lack of a Bill of Rights. They advocated for states' rights and individual liberties. Thus, Monroe had affiliations with both sides, while Henry and Mason were staunchly Anti-Federalist.
