Ten weeks after Pearl Harbor, Executive Order 9066 authorized removing about 120,000 people of Japanese ancestry from the West Coast, roughly two-thirds of them citizens, to ten remote camps. No mass disloyalty was found, and a federal commission decades later cited race prejudice, war hysteria and failed leadership. Sons volunteered from the camps, while other migrants sometimes moved into the homes left behind.
Many historians prefer 'incarceration' to 'internment.' The government's military-necessity rationale was rejected by the 1982 commission, and the 2018 repudiation of Korematsu was dicta rather than a formal overruling.
