World War I: Conscription Laws

Share this post:

(The following is a guest post by Margaret Wood, a legal reference librarian at the Law Library of Congress.)


Six weeks after the declaration of war against Germany on April 6, 1917, ch. 1, 40 Stat.1, Congress passed the Selective Service Act. Initially, President Woodrow Wilson and Congress had hoped the needed 1 million men would volunteer for the army. But when by May only about 73,000 men had signed up, it was clear other measures needed to be taken.

The United States had experimented with conscription laws during the Civil War. The Confederacy had passed the first such law (S.32) on April 16, 1862. The Union followed by passing a conscription law on March 3, 1863, ch. 75, 12 Stat. 731. Both Union and Confederate subscription laws allowed for a number of exemptions as well as including the very unpopular measure of “substitutes,” which allowed wealthy men to pay for someone to serve in their stead.

However, the World War I Selective Service Act, ch. 15, 40 Stat. 76, specifically forbade the use of substitutes. This law, which was passed on May 18, 1917, applied to all “male citizens, or male persons … who have declared their intention to become citizens, between the ages of twenty–one and thirty.” The law directed that quotas for each state should be established based on the state’s population. The law also addressed the issue of exemptions based on moral objections, as well as occupation. Those exempted from the draft included federal and state officials and judges, religious ministers, seminary students and any person who was found to be a “member of a well-recognized religious sect or organization … whose existing creed or principles forbid its members to participate in war in any form.” However as the law went on to state, “no person so exempted shall be exempted from service in any capacity that the President shall declare to be noncombatant.” The law also exempted persons in certain classes or industries, including workmen in armories and those in agriculture whose work was “necessary to the maintenance of the Military Establishment.”

Ultimately the regulations issued by the president divided up the men subject to conscription into five classes. This law directed the president to create local draft boards in each county that were to consist of three or more members who were to determine all questions of exemption in their jurisdiction. The law further set up district boards that could hear appeals from the county draft boards.

Between Aug. 6-19, 1918, the House Committee on Military Affairs held hearings to consider expanding the ages between which men should be drafted.  Secretary of War Newton D. Baker testified at the hearing that, “There are two ways of fighting this war. One is to make every possible effort and win it soon, and the other is to proceed in a somewhat more leisurely fashion and win it late.” Congress appears to have preferred the first method, and a little less that two weeks later amended the Selective Service Act (ch. 166, 40 Stat. 955). This law made all men between the ages of 18 and 45 subject to the draft. The penalties for evading the draft remained the same. The evader would be charged with a misdemeanor and subject to a year of imprisonment unless the evader was subject to military law, in which case they would be tried by a court-martial. Congress anticipated a shortage of “manpower” and directed that soldiers’ wives should not be disqualified from working for the government because they were married women.  Indeed, 10 years after the war, Congress held hearings about the effect of the universal draft and conscription in times of war.

  1. Given the time and logic of this period in american history what would have been considered a valid or “well-recognized religious sect or organization” at the time? I’m thinking there wasn’t much and because it had to be a “well-recognized religious sect or organization”, conscription laws during WW1 would have been very discriminant of other religions.

  2. This act would lead to the arrest and imprisonment of Emma Goldman. She spoke out against the draft in 1917 and was arrested for interfering with conscription. She made a speech in front of the jury, which can be read online as part of her papers archive, in which she defended the rights of citizens to refuse to serve in an unjust war.

  3. Democrats who control the purse strings of the House of representatives are under the illusion Donald Trum’s hands are tied and that he cannot build a wall without their blessings. Wrong. Donald Trump has plenary war powers and can enact wartime legislation declaring mexican border jumping of our country to constitute an act of war. By doing so he can then invoke the draft and start drafting hundreds of thousands of milennials, put them into uniform and use them to deal with the invading panamanians, salvadorans, hondurans, terrorists, etc for as long as it takes to get a handle on this ongoing democratic sanctioned invasion which the rest of will not stand for. We don’t need Ms. Pelosi’s approval to spend 5, 10, or whatever beillions it takes to build a wall. By invoking the drafting provisions of the civil service act, the newly drafted soldiers can then be ordered to build the wall for free in the interests of national security. That would put a stopper in these communistic admiring democrats who would be better off outside of the U.S. We don’t want them here.

  4. Wow, just wow, this is exactly what I was looking for. Real stellar job.

  5. I just had a question about WWI. I was wondering if a person said he had a wife to support on the draft registration, was that reason enough not to serve? Thanks, Genie

  6. I wonder if an only child–a son–would have been excluded?

    • Hi there,

      Your best bet to getting a definitive answer would be to ask a librarian familiar with the era, and you can do that here:


  7. Were PRT (Phila. Rapid Transit) operators exempt during WW I? Curious why my uncle (b 1901) served and my dad (b 1903) did not. Was employment by PRT the answer?

    • Hi there,

      Thanks for writing. Not sure this is knowable at this point, but you can try our Ask a Librarian service, which puts you in touch with a reference librarian, just as if you’d walked into the Library.

      Good luck!

  8. Gil Bunker’s dad could not serve because he was too young.

  9. How did my grandfather get drafted into World War at 16 and become a sergeant with in 6 months

  10. Hi, I’m writing a research paper and I’m curious how long people were required to stay in the military if they were drafted? Was it just until the end of the war? Thank you!

    • Hi there,

      You’ll want to use our Ask a Librarian reference desk for this, as they would be the experts. This post originally appeared on the law blog, but you might want to detail your question to the Veterans History Project, as they might know that offhand. In either event, start here. It will put you in touch with a reference librarian, just as if you walked into the library:

      Good luck,

  11. my father b. 1899 failed the draft physical in abt. 1918. I understand an x ray showed his heart to be too large. did they x ray draftees for WWWI service?

    • Hi there,

      Your best bet will be to ask one of our reference librarians, via the Ask a Librarian service:

      Good luck,

  12. I have a question about the draft in WW1. My great grandfather, William Earl Hughes, was born 26 Jan 1895. I have never been able to find a draft card for him. I know almost nothing about him after about October 1916. I have heard a family oral tradition that he served in WW1 in the Rainbow Division. If he were already serving in the military on the day when he was required to register for the draft (June 5, 1917 I believe), would he still be required to register for the draft? Might that explain why I can find no draft card for him? Thanks

    • Hi there,

      The answer to your question would likely be at the National Archives, which holds draft records, etc. Here’s a link to get started:

      All best,
