Internment of German Americans

With the U.S. entry into World War I after Germany's unrestricted submarine warfare, German nationals were automatically classified as enemy aliens. Two of four main World War I-era internment camps were located in Hot Springs, North Carolina, and Fort Oglethorpe, Georgia. Attorney General A. Mitchell Palmer wrote that "All aliens interned by the government are regarded as enemies, and their property is treated accordingly."
By the time of WWII, the United States had a large population of ethnic Germans. Among residents of the United States in 1940, more than 1.2 million persons had been born in Germany, 5 million had two native-German parents, and 6 million had one native-German parent. Many more had distant German ancestry. During WWII, the United States detained at least 11,000 ethnic Germans, overwhelmingly German nationals between the years 1940 and 1948 in two designated camps at Fort Douglas, Utah, and Fort Oglethorpe, Georgia. The government examined the cases of German nationals individually, and detained relatively few in internment camps run by the Department of Justice, as related to its responsibilities under the Alien Enemies Act. To a much lesser extent, some ethnic German US citizens were classified as suspect after due process and also detained. Similarly, a small proportion of Italian nationals and Italian Americans were interned in relation to their total population in the US. The United States had allowed immigrants from both Germany and Italy to become naturalized citizens, which many had done by then.
