The Alien Enemies Act has been used three times in American history, all in connection with declared wars.
War of 1812:
During the War of 1812, all British nationals living in the U.S. were required to report information including their age, length of time in the country, place of residence, family description and whether they had applied for naturalization.
WW1:
During World War I, President Woodrow Wilson invoked it against nationals of the Central Powers: the German Empire, Austria-Hungary, the Ottoman Empire and Bulgaria. U.S. authorities used the law to place over 6,000 "enemy aliens" — many of them Germans — in internment camps, with some remaining in detention up to two years after fighting had ended.
The U.S. Marshals Service says it registered 480,000 German "enemy aliens" and arrested 6,300 between the declaration of war in April 1917 and the armistice in November 1918.
WW2:
FDR invoked the act after the attack on Pearl Harbor, designating Japanese, German and Italian nationals as "alien enemies" during World War II.
Roosevelt's proclamation required residents from all three countries to register with the U.S. government and authorized the internment of any alien enemy "deemed potentially dangerous to the peace and security of the US."
By the end of WWII, over 31,000 suspected enemy aliens and their families — including Jewish refugees from Nazi Germany — had been interned at camps and military facilities across the U.S.
