The Federalists Papers?

The agreement that helped the Anti-federalists to finally approve the Constitution was the inclusion of an Amendment about slavery.

To find the answer to this question, one could start by researching the main concerns and objections held by the Anti-federalists. The Anti-federalists were opposed to the Constitution because they believed it gave too much power to the central government and did not adequately protect individual rights. One of their major concerns was the institution of slavery.

During the drafting and ratification process of the Constitution, the issue of slavery was a contentious topic. Many Anti-federalists feared that the Constitution did not do enough to prevent the spread of slavery or protect the rights of enslaved individuals.

To address these concerns, a compromise was reached between the Anti-federalists and the Federalists, who supported the Constitution. This compromise involved the inclusion of an Amendment about slavery, which helped the Anti-federalists to finally approve the Constitution.

It is important to note that the Bill of Rights, the Federalist Papers, and the rewriting of the Preamble were all significant factors in the ratification of the Constitution and addressing the concerns of various factions. However, in the context of the question, the agreement specifically related to slavery was the one that helped the Anti-federalists to approve the Constitution.
