When was the Japanese internment?

President Franklin D. Roosevelt authorized the internment with Executive Order 9066, which allowed local military commanders to designate "military areas" as "exclusion zones", from which "any or all persons may be excluded." Twelve days later, this power was used to declare that all people of Japanese ancestry were excluded from the entire Pacific coast, including all of California and most of Oregon and Washington. In 1944, the Supreme Court upheld the constitutionality of the exclusion, removal, and detention, arguing that it is permissible to curtail the civil rights of a racial group when there is a "pressing public necessity."
