<P> Owing to very slow enlistment following the U.S. declaration of war against Germany on April 6 , the Selective Service Act of 1917 ( 40 Stat. 76 ) was passed by the 65th United States Congress on May 18 , 1917 , creating the Selective Service System to raise an army to fight in Europe . The Act gave the President the power to conscript men for military service . All men aged 21 to 30 were required to register for military service for a service period of 12 months . As of mid-November 1917 , all registrants were placed in one of five new classifications . Men in Class I were the first to be drafted , and men in lower classifications were deferred . Dependency deferments for registrants who were fathers or husbands were especially widespread . The age limit was later raised in August 1918 to a maximum age of 45 . The military draft was discontinued in 1920 . </P>
