The Japanese Internments saw approximately 120,000 Japanese Americans forcibly relocated and interned in camps during World War II. This was in response to the bombing of Pearl Harbor by Japanese forces in 1941, after which President Roosevelt issued an executive order allowing for exclusion zones and internment. Japanese Americans were held in poor conditions in internment camps until 1945, when internees were released with little support. In later decades, Japanese American advocacy groups pursued redress for the injustice of the internments, culminating in presidential apologies and reparations being issued in the 1980s and 1990s.
