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.
Anti-Federalist Papers
During the lengthy and heated national debate following this convention, both groups wrote extensively in favor of their respective positions. The anti-Federalist papers are a selection of the written arguments against the US Constitution by those known to posterity as the anti-Federalists. As with the Federalist papers, these essays were originally published in newspapers. The most widely known are "a series of sixteen essays published in the New York Journal from October 1787 through April 1788 during the same period. The anti-Federalist was appearing in New York newspapers, under the pseudonym 'Brutus'."
