United States Civil Administration of the Ryukyu Islands
The United States Civil Administration of the Ryukyu Islands (USCAR) was established, effective 15 December 1950, by a directive of Headquarters Far East Command. That directive ordered Commander-in-Chief Far East, Gen. Douglas MacArthur, to organize a civil administration for the Ryukyu Islands in accordance with JCS 1231/14 October 4, 1950. USCAR continued to function under the Department of the Army (formerly the War Department) from 1950 to 1971.
