what was the term for americans who opposed ratifying the constitution?

The term for Americans who opposed ratifying the Constitution was "Anti- Federalists." They were a political group in the late 18th century who opposed the creation of a stronger federal government as proposed in the 1787 Constitution. The Anti-Federalists feared that the new national government would be too powerful and threaten individual liberties, and they strongly advocated for a bill of rights to be added to the Constitution. They supported stronger state governments and were concerned about the potential for the president to become like a monarch. Their opposition led to the eventual adoption of the Bill of Rights to protect individual freedoms. Key figures included Patrick Henry and George Mason, among others.
