What was the title of the essays written by Madison, Hamilton, and Jay in favor of ratification?

The correct title of the essays written by Madison, Hamilton, and Jay in favor of ratification is "The Federalist Papers." This collection of 85 essays was published in 1787 and 1788 with the primary purpose of persuading the citizens of New York to support the ratification of the United States Constitution.

The essays address various concerns about the proposed government structure, including the importance of a strong central government, checks and balances, and the dangers of factions. The Federalist Papers are not only significant for their role in the ratification process but also serve as essential resources for understanding the intentions of the framers of the Constitution.

The other titles provided do not relate to this specific historical context. "The Social Contract Documents" suggests works related to social contract theory, "The Independence Diaries" implies a collection about the American Revolution, and "The Development of Liberty Papers" hints at discussions around liberty that do not specifically reference the ratification debates. Therefore, "The Federalist Papers" stands out as the accurate answer.
