The Espionage Act of 1917 and the Sedition Act of 1918 authorized the ban on materials advocating treason or insurrection and prohibited disloyal utterances. These acts were aimed at curbing dissent during World War I and were used to target politically radical groups, including socialists and anarchists, who opposed the war or the government’s policies. Together, they allowed for the prosecution of individuals for speech deemed disloyal or seditious.
