Who made up the antifederalists?

The Antifederalists were a diverse group of individuals who opposed the ratification of the U.S. Constitution in the late 18th century. They included prominent figures such as Patrick Henry, George Mason, and Elbridge Gerry, as well as ordinary citizens who feared a strong central government. Antifederalists advocated for states' rights and the protection of individual liberties, arguing that the Constitution lacked sufficient safeguards for these rights. Their concerns ultimately led to the addition of the Bill of Rights to the Constitution.
