Internment of Italian Americans
The internment of Italian Americans refers to the US government's internment of Italian nationals during World War II. As was customary after Italy and the US were at war, they were classified as "enemy aliens" and some were detained by the Department of Justice under the Alien and Sedition Act. In practice, however, the US applied detention only to Italian nationals, not to US citizens or long-term US residents.
