One way the U.S. Government limited 1st Amendment rights during World War I was with the Espionage Act of 1917 and the Sedition Act of 1918.

1. The Espionage Act of 1917: This law was passed shortly after the U.S. entered World War I. It made it a crime to interfere with the operation or success of the military. This included any attempt to cause insubordination, disloyalty, or refusal of duty in the military or naval forces. It also made it illegal to obstruct the recruitment or enlistment of potential service members. This law was used to prosecute those who spoke out against the war or the draft.

2. The Sedition Act of 1918: This law was an extension of the Espionage Act. It further restricted First Amendment rights by making it a crime to "willfully utter, print, write, or publish any disloyal, profane, scurrilous, or abusive language about the form of government of the United States" or to "willfully urge, incite, or advocate any curtailment of production" of the things "necessary or essential to the prosecution of the war." This law was used to prosecute those who criticized the government, its symbols, or its war effort.

Both of these laws significantly limited the freedom of speech protected by the 1st Amendment. They were both eventually repealed, but not before they were used to suppress dissent and criticism during World War I.
