On February 19, 1942, President Franklin Delano Roosevelt issued Executive Order 9066, which allowed local military commanders to designate “military areas” as “exclusion zones,” from which “any or all persons may be excluded.” Accordingly, 127,000 US residents of Japanese ancestry, most of whom were US citizens, were removed from the Pacific Coast. They would be interned in “relocation” camps in the interior portions of the country, with little regard for the significant loss of property and assets and the disruption of traditional family structure this caused.
