Matthew Lyon

Identification: American politician

Significance: Lyon was convicted of criticizing President John Adams under the terms of the Sedition Act of 1798

Matthew “Ragged Matt the Democrat” Lyon, a Revolutionary War veteran who had immigrated to America from Ireland, was elected to Congress to represent Vermont in 1797. In several published letters, he criticized President John Adams, claiming that Adams was engaged “in a continual grasp for power” and “an unbounded thirst for ridiculous pomp.” Lyon’s letters landed him in federal court. He became the first person tried under the Sedition Act of 1798, which made it a crime to criticize the president, Congress, or the U.S. government “with the intent to defame them or bring them into disrepute.”

Lyon later wrote that his defense “consisted of an appeal to the jury of the unconstitutionality of the law,” and “the innocence of the passage in my letter.” However, Supreme Court justice William Paterson, presiding as a circuit judge, rejected Lyon’s constitutional defense, instructing the jury to follow the law, which he declared to be constitutional. After the jury convicted Lyon, Paterson sentenced him to four months in jail and a one-thousand dollar fine.

Afterward members of Adams’ Federalist Party expected Lyon to lose his re-election bid because of his conviction; however, Vermont voters returned him to office with almost twice the number of votes of his closest rival. In the 1880 presidential election, Adams lost to Thomas Jefferson, in part because of the unpopularity of the Sedition Act.
