The Sedition Act of 1918 was an act that extended the Espionage Act of 1917 to put more limitations on people's right to freely express themselves as an attempt to stop many Americans' disapproval of the U.S. involvement in World War I. The Act forbade people to use a disloyal, profane, scurrilous, or abusive language against the war efforts, the government, the flag or the armed forces. Many Americans considered it a violation of the freedom of speech right guaranteed under the First Amendment.
