This is a topical guide to articles about the history of the Japanese American internment during World War II.
During World War II, about 120,000 people of Japanese descent were forcibly relocated and incarcerated in ten internment camps in the United States, operated by the War Relocation Authority (WRA), mostly in the western interior of the country. About two-thirds were U.S. citizens. These actions were initiated by Executive Order 9066, issued by President Franklin D. Roosevelt on February 19, 1942, following Imperial Japan's attack on Pearl Harbor on December 7, 1941.
About 127,000 Japanese Americans then lived in the continental U.S., of whom about 112,000 were removed from the West Coast. About 80,000 were Nisei ('second generation'; American-born Japanese with U.S. citizenship) and Sansei ('third generation', the children of Nisei). The rest were Issei ('first generation') immigrants born in Japan, who were ineligible for citizenship. In Hawaii, where more than 150,000 Japanese Americans comprised more than one-third of the territory's population, only about 1,330 were incarcerated.
Most Japanese Americans were first held in temporary assembly centers, run by the Army's Wartime Civil Control Administration, before they were sent to internment camps in California, Arizona, Wyoming, Colorado, Utah, Idaho, and Arkansas. The internees were prohibited from taking more than they could carry into the camps, and many of them were forced to sell either some or all of their property, including their homes and their businesses.
