What is the historical importance of enemy aliens in World War 1?

During World War I, "enemy aliens" referred to individuals from nations at war with the Allies, particularly Germans, Austrians, and Hungarians, who resided in Allied countries. Many were subjected to internment, surveillance, and discrimination, reflecting the societal fears and xenophobia prevalent during wartime. This treatment highlighted the tensions between national security and civil liberties, influencing future policies regarding Immigration and the treatment of foreign nationals in times of conflict.
