Executive Order 9066
Executive Order 9066 was passed on February 19, 1942 by President Franklin Roosevelt. Its intent was to permit the Secretary of War to declare certain areas as military zones. He had the sole power of deciding where the military zones were and who was included. Although the order did not explicitly state which ethnic groups would be targeted, it was inferred. Executive Order 9066 made way for the creation of internment camps.
"[...] By virtue of the authority vested in me as President of the United States, and Commander in Chief of the Army and Navy, I hereby authorize and direct the Secretary of War, and the Military Commanders whom he may from time to time designate, whenever he or any designated Commander deems such action necessary or desirable, to prescribe military areas in such places [...] from which any or all persons may be excluded, and with respect to which, the right of any person to enter, remain in, or leave shall be subject to whatever restrictions the Secretary of War or the appropriate Military Commander may impose in his discretion." - Executive Order 9066
