Draft--Congress, which under the Constitution of the United States has the sole authority to raise armies, first legislated involuntary conscription to fill the ranks of the military--a draft--in the Civil War. It was used again in World War I and World War II. Although the draft laws were due to expire July 9, 1950, Congress quickly passed a two-year extension. By September 1950, 50,000 men were being drafted each month, and by 1952, 20,000 to 30,000 conscripts were sent to Korea each month.
