On Orders of the President
In the aftermath of the attack on Pearl Harbor, the U.S. government immediately arrested people they considered “potentially dangerous enemy aliens” under Presidential Proclamations 2525, 2526, and 2527. The term “internment” refers to the legally permissible, though morally questionable, detention of “enemy aliens” in times of war. Based on these proclamations, the federal government arrested nearly 8,000 individuals across the U.S. and its territories, including World War II-era internees sent to Angel Island.
An additional 120,000 people, two-thirds of them American citizens, were removed from their homes after President Franklin D. Roosevelt issued Executive Order 9066 on February 19, 1942. While sometimes thought of as internees, this group is more accurately referred to as being incarcerated. Both foreign- and U.S.-born Japanese Americans experienced forced removal and incarceration under the control of the War Relocation Authority (WRA). None of those affected by Executive Order 9066 were sent to Angel Island.
