May 16, 1918 - Sedition Act Passed and Used to Punish Critics of World War I
On this day in 1918, an amendment to the Espionage Act of 1917 (known as the Sedition Act) was passed. The law imposed criminal penalties on all forms of expression critical of the government, its symbols, or the nation's war mobilization for World War I. Approximately 900 people were convicted under the law, while hundreds of non-citizens were deported without a trial.
