Espionage Act of 1917

The Espionage Act of 1917 is a U.S. federal law passed during World War I aimed at preventing spying and related activities that could harm national security. It made it illegal to interfere with military operations or support America’s enemies. The law also prohibited the sharing of information that could aid enemy nations. Penalties for violations included fines and imprisonment. Over the years, the act has been used in various contexts, affecting not only military-related issues but also cases involving free speech and dissent, particularly during wartime.
