War History Online:
Internment of Japanese Americans during the Second World War is widely known and well documented. However, less is known about the thousands of “ethnic Germans” who were also detained, as well as smaller numbers of Italians and Italian Americans.
The precedent was set during the First World War when laws dating back to the 18th Century were used to authorize the detention of anyone considered to be an “enemy alien” and therefore a possible threat to security and the war effort.
The Government set up four camps. The main ones were located in Hot Springs, CA and at Fort Oglethorpe in Georgia. These camps were referred to as DOJ (Department of Justice) Camps. Those interned included not only German nationals but also those of recent German descent. As they were now considered to be enemy aliens, many had their homes and property seized by the Government. By 1940, Germans made up a large percentage of the “non-American” population in the United States. There were approximately 1.2 million German nationals as well as another 11 million US citizens who had at least one German-born parent.
As the war in Europe continued, America was laying the groundwork. The 1940 census introduced a new question. It now required that all respondents included their ethnicity. This would make them easier to identify after America entered the war.
Also in 1940, a new law was passed so that all aliens over the age of 14 had to be registered. Following the attack on Pearl Harbor in 1941, but before America had declared war on Germany, Roosevelt announced that Germans, Italians, and Japanese were now considered to be enemy aliens under the DOJ Alien Enemy Control Unit Program.
Anyone who could be described as an ethnic German came under suspicion. Cases were looked at on an individual basis. In theory, people were only to be detained if they there was some evidence to suggest that they posed a threat. As a result, 11,000 people were taken to DOJ camps. The majority of these were German nationals, but the number also included US citizens of German descent. The number of those who spent the war in such camps was, in fact, much higher than the 11,000 detainees.
Only enemy aliens could be interned by law. However, their families could come along voluntarily. Although living in the DOJ camp wasn’t an ideal option for a family, many chose this rather than being separated. In addition, families could be left without income if the main earner was detained so the camp may have been the most practical solution.
The American camps also held a large number of Germans who had been living in Latin America. An estimated 4,058 people were thought to have been expelled and sent to the United States to be interned. A small number of these were believed to be Nazi party members who were recruiting for the Nazi Party’s overseas branch. A further eight were suspected of spying.
Under Roosevelt’s orders, a total of 4,058 Germans were removed as well as 2,264 Japanese and 288 Italians. Most were sent to the two main camps which were in Ellis Island or Crystal City in Texas. Not all the Latin American countries deported their German population. Several, including Brazil, Mexico, and Venezuela among others set up their own camps.
