Executive Order 9066 - The Order

The Order

The order authorized the Secretary of War and U.S. armed forces commanders to declare areas of the United States as military areas "from which any or all persons may be excluded," although it did not name any nationality or ethnic group. It was eventually applied to one-third of the land area of the U.S. (mostly in the West) and was used against those with "Foreign Enemy Ancestry" — Japanese, and Korean, who were considered to have Japanese nationality (since Korea had been under Japanese rule since 1910).

The order led to the internment of Japanese Americans or AJAs (Americans of Japanese Ancestry); some 120,000 ethnic Japanese people were held in internment camps for the duration of the war. Of the Japanese interned, 62% were Nisei (American-born children of immigrants from Japan, who were natural born American citizens) or Sansei (children of Nisei, also American citizens) and the rest were Issei (Japanese immigrants, resident aliens).

Japanese Americans were by far the most widely affected group, as all persons with Japanese ancestry were removed from the West Coast and southern Arizona. In Hawaii, where there were 140,000 Americans of Japanese Ancestry (constituting 37% of the population), only selected individuals of heightened perceived risk were interned.

Americans of Italian and German ancestry were also targeted by these restrictions, including internment. 11,000 people of German ancestry were interned, as were 3,000 people of Italian ancestry, along with some Jewish refugees. The Jewish refugees who were interned came from Germany, and the U.S. government didn't differentiate between ethnic Jews and ethnic Germans (Jewish was defined as religious practice). Some of the internees of European descent were interned only briefly, and others were held for several years beyond the end of the war. Like the Japanese internees, these smaller groups had American-born citizens in their numbers, especially among the children. A few members of ethnicities of other Axis countries were interned, but exact numbers are unknown.

Secretary of War Henry L. Stimson was responsible for assisting relocated people with transport, food, shelter, and other accommodations.
