What compromise was made between Federalists and Anti-Federalists to ratify the Constitution?

The correct answer is the addition of the Bill of Rights. This compromise was essential for securing the ratification of the Constitution by addressing the concerns raised by Anti-Federalists regarding the potential for government overreach and the protection of individual liberties. The Anti-Federalists feared that a strong central government could infringe upon the rights of citizens and the rights of the states. To alleviate these concerns and encourage ratification, the Federalists promised to add a Bill of Rights as the first order of business once the new government was established.

The Bill of Rights, ratified in 1791, consists of the first ten amendments to the Constitution and explicitly enumerates the rights and freedoms guaranteed to individuals, such as freedom of speech, religion, and the right to a fair trial. This assurance provided the necessary support to unify both factions and helped to foster a stronger commitment to the new Constitution.

While the inclusion of checks and balances, the implementation of federalism, and the creation of a strong executive branch were significant components of the Constitution itself, they did not directly address the specific concerns of the Anti-Federalists in the same way that the Bill of Rights did.
