Final answer:
The Anti-Federalists demanded a bill of rights be added to the Constitution to protect individual liberties against central government powers.
Step-by-step explanation:
The Anti-Federalists demanded the inclusion of a bill of rights in the Constitution to protect individual liberties against potential government tyranny. They were concerned about the strong central powers given to the federal government and feared that without explicit protections, basic freedoms could be infringed upon. Despite their efforts, the Constitution was ratified without a bill of rights; however, the subsequent adoption of the first ten amendments, known as the Bill of Rights, addressed the Anti-Federalists' concerns and facilitated the eventual ratification by all states.
