On this day in 1917, some two months after America’s formal entrance into World War I against Germany, the United States Congress passes the Espionage Act.

Mitchell Palmer, the United States attorney general under President Woodrow Wilson, the Espionage Act essentially made it a crime for any person to convey information intended to interfere with the U.S. armed forces prosecution of the war effort or to promote the success of the country’s enemies. Anyone found guilty of such acts would be subject to a fine of $10,000 and a prison sentence of 20 years.
One of the most famous activists arrested during this period, labor leader Eugene V. Debs, was sentenced to 10 years in prison for a speech he made in 1918 in Canton, Ohio, criticizing the Espionage Act. Debs appealed the decision, and the case eventually reached the U.S. Supreme Court, where the court upheld his conviction. Though Debs’ sentence was commuted in 1921 when the Sedition Act was repealed by Congress, major portions of the Espionage Act remain part of United States law to the present day.
