The Anti-Federalist Papers are a collection of articles, written in opposition to the ratification of the 1787 United States Constitution. Unlike the Federalist Papers written in support of the Constitution, the authors of these articles, mostly operating under pen names, were not engaged in a strictly organized project. Thus, unlike the Federalist Papers, it is a matter of opinion what writings specifically are included and in what order they are best presented. The most frequently cited modern collection, The Complete Anti-Federalist, was produced by Herbert Storing and is considered the authoritative compendium on the publications. Major Anti-Federalist authors included Cato (likely George Clinton), Brutus (likely Robert Yates), Centinel (Samuel Bryan), and the Federal Farmer (either Melancton Smith, Richard Henry Lee, or Mercy Otis Warren). Speeches by Patrick Henry and Smith are often included as well. One of the major points of the articles was the danger the new Constitution would bring without a statement of individual rights. Some of the Anti-Federalist concerns were addressed in the Bill of Rights, which was added later. (http://libertypundits.com/wp-content/uploads/2010/03/3-anti-federalist.jpg)
