The War Office has the unique ability to censor letters, media reports and controls the flow of information from forward-deployed units to the general public. While most military members know this inherently, it might surprise you to understand how censorship got its legs in America and what it looks like today.

In all likelihood, there was probably some censorship happening during the Civil War, but because so many service personnel were illiterate, it’s hard to know exact numbers. But there had to be some censorship since often letters crossed into enemy territory. But the real start to military censorship started during WWI and the Espionage Act of 1917.

This act allowed the government to fine citizens for interference with recruiting troops or the refusal to perform military duties. The charge came with a fine of $10,000 and 20 years in prison. Within six months of the act being signed, there were over 1,000 people imprisoned.

The Sedition Act of 1918 meant that it became a crime to criticize the government, the Constitution, the flag, or the uniform of men in military service. This applied to both speeches and writing. Under the two laws, thousands of people were imprisoned for acts of nonviolent protest against the war. Additionally, at least 75 newspapers lost mailing privileges and were under governmental pressure to change their outward-facing editorial attitudes.
