The U.S. VIII Corps was a corps of the United States Army that saw service during various times over a fifty-year period during the 20th century. The VIII Corps was organized 26–29 November 1918 in the Regular Army in France and demobilized on 20 April 1919. The VIII Corps was soon reactivated, being constituted in the Organized Reserves in 1921. It was allotted to the Regular Army in 1933 and activated on 14 October 1940 at Fort Sam Houston, Texas. The VIII Corps fought across Europe from Normandy to Czechoslovakia in World War II. After World War II, the corps was inactivated and reactivated several times, with the final inactivation occurring in 1968.
