The Sedition Act of 1918
From The United States Statutes at Large, V. 40. (April 1917-March 1919).

DOCUMENT DESCRIPTION

The Sedition Act of 1918, enacted during World War I, made it a crime to "willfully utter, print, write, or publish any disloyal, profane, scurrilous, or abusive language about the form of the Government of the United States" or to "willfully urge, incite, or advocate any curtailment of the production" of the things "necessary or essential to the prosecution of the war." The act, along with other similar federal laws, was used to convict at least 877 people in 1919 and 1920, according to a report by the attorney general. In 1919, the Court heard several important free speech cases -- including Debs v. United States and Abrams v. United States -- involving the constitutionality of the law. In both cases, the Court upheld the convictions as well as the law.
