The Antifederalists wanted a Bill of Rights added to the Constitution. There was significant concern among the Antifederalists that the Constitution didn’t protect the rights of individuals. Once the Constitution was sent to the states for ratification, many states expressed concern about the perceived lack of protection of individual rights. Several states said they would not ratify the Constitution without the addition of the Bill of Rights. After many years of dealing with abuses of individual rights while colonies of Great Britain, and then fighting a war partially because of this, the states were not willing to risk this happening again. Therefore, a promise was made to add a Bill of Rights to the Constitution once the Constitution was ratified. After this promise was made, those states that were against the Constitution agreed to vote for its ratification. This promise also eased the fears the Antifederalists had about the Constitution.
