To address the concerns of many Antifederalists during the debate over ratification of the Constitution, the Federalists agreed to add a bill of rights. This agreement was significant because the Antifederalists were worried that the original Constitution did not do enough to protect individual rights.
Adding a bill of rights would address these concerns by explicitly outlining specific rights and protections for individuals. The Bill of Rights, which includes the first ten amendments to the Constitution, guarantees freedoms such as freedom of speech, religion, and the right to a fair trial.
By agreeing to add a bill of rights, the Federalists aimed to reassure the Antifederalists that their concerns about individual liberties and rights would be respected and protected under the new Constitution. This compromise played a crucial role in securing the ratification of the Constitution.
