While it's easy to find information on the Federalist Papers, finding out about the Antifederalist Papers is a bit more difficult. Like the Federalist Papers, these were a series of articles written by different authors, most under pseudonyms. But instead of being written in support of the new Constitution, these opposed it for various reasons. In a nutshell, the antifederalists opposed a strong central federal government in favore of States Rights. A key stumbling block was the original Constitution failed to include a statement of individual rights. It was in answer to the strident opposition of the antifederalists that the Bill of Rights was later added to the Constitution.
The Antifederalist Papers weren't part of a unified movement and thus were never identified as such and put together in a single form. Morton Borden collected 85 of the most significant and ordered them in response to the 85 Federalist Papers, publishing his work, The Antifederalist Papers, in 1965. Another collection was published in 1981: The Complete Anti-Federalist by Herbert Storing. It's currently available as a three-volume set.
Among the major Antifederalist authors are such well known names as Patrick Henry and George Mason. Articles signed by Cato are thought to have been written by George Clinton, vice president to both Thomas Jefferson and James Madison. Those signed by Federal Farmer, praised for their thoughtfulness and persuasiveness at the time, have been attributed to Richard Henry Lee, Melancton Smith, and Mercy Otis Warren. It's not known for sure who authored those articles, but they remain among the most widely read works of Antifederalists.
For the purposes of this site, we've opted to use Borden's index of articles.
