How and why did the government restrict civil liberties during World War 1?

During World War I, the U.S. government restricted civil liberties primarily through the Espionage Act of 1917 and the Sedition Act of 1918, which aimed to suppress dissent and prevent anti-war sentiment. These laws criminalized activities deemed harmful to the war effort, including speech and publications that criticized the government or military. The government justified these restrictions as necessary for national security and unity during a time of crisis, arguing that they were essential to maintain morale and prevent sabotage. However, these measures led to significant debates about free speech and civil rights, with many individuals and groups opposing the infringements on personal liberties.
