Executive Order 9981 was an executive order issued on July 26, 1948, by President Harry S. Truman. It abolished discrimination "on the basis of race, color, religion or national origin" in the United States Armed Forces. The Order led to the re-integration of the services during the Korean War (1950–1953). It was a crucial event in the post-World War II civil rights movement and a major achievement of Truman's presidency. Executive Order 9981 was inspired, in part, by an attack on Isaac Woodard who was an American soldier and African-American World War II veteran. On February 12, 1946, hours after being honorably discharged from the United States Army, he was attacked while still in uniform by South Carolina police as he was taking a bus home. The attack left Woodard completely and permanently blind. President Harry S. Truman ordered a federal investigation.

Harry S. Truman was the 33rd president of the United States, serving from 1945 to 1953. A member of the Democratic Party, he previously served as a United States senator from Missouri from 1935 to 1945 and briefly as the 34th vice president in 1945 under Franklin D. Roosevelt. Assuming the presidency after Roosevelt's death, Truman implemented the Marshall Plan in the wake of World War II to rebuild the economy of Western Europe and established both the Truman Doctrine and NATO to contain the expansion of Soviet communism. He proposed numerous liberal domestic reforms, but few were enacted by the conservative coalition that dominated the Congress.
