The Federalist Papers
The Federalist (later known as The Federalist Papers) is a collection of 85 articles and essays written by Alexander Hamilton, James Madison, and John Jay under the pseudonym "Publius" to promote the ratification of the United States Constitution. The first 77 of these essays were published serially in the "Independent Journal", the "New York Packet", and "The Daily Advertiser" between October 1787 and April 1788. A two-volume compilation of these 77 essays and eight others was published as The Federalist: A Collection of Essays, Written in Favour of the New Constitution, as Agreed upon by the Federal Convention, September 17, 1787 by publishing firm J. & A. McLean in March and May 1788. The collection was commonly known as "The Federalist" until the name "The Federalist Papers" emerged in the 20th century.
Confederation Period
Ratification of the Constitution required the approval of nine states. The ratification debates in Massachusetts, New York, Pennsylvania, and Virginia were of particular importance, as they were the four largest and most powerful states in the nation. Those who advocated ratification took the name Federalists. To sway the closely divided New York legislature, Hamilton, Madison, and Jay anonymously published "The Federalist Papers", which became seminal documents that affected the debate in New York and other states. Opponents of the new constitution became known as Anti-Federalists. Though most Anti-Federalists acknowledged the need for changes to the Articles of Confederation, they feared the establishment of a powerful, and potentially tyrannical, central government. Members of both camps held wide ranges of views; for example, some Anti-Federalists like Luther Martin wanted only minor changes to the Articles of Confederation, while others such as George Mason favored a less powerful version of the federal government proposed by the Constitution. Federalists were strongest in eastern, urban counties, while Anti-Federalists tended to be stronger in rural areas. Each faction engaged in a spirited public campaign to shape the ratification debate, though the Federalists tended to be better financed and organized. Over time, the Federalists were able to convince many in the skeptical public of the merits of the new Constitution.
