US Congress passes 1st peace-time conscription bill authorizing military draft

In the United States, military conscription, commonly known as "the draft", has been employed by the U.S. federal government in six conflicts: the American Revolutionary War, the American Civil War, World War I, World War II, the Korean War, and the Vietnam War. The fourth incarnation of the draft came into being in 1940, through the Selective Training and Service Act; this was the country's first peacetime draft. From 1940 until 1973, during both peacetime and periods of conflict, men were drafted to fill vacancies in the U.S. Armed Forces that could not be filled through voluntary means. Active conscription in the United States ended in January 1973, and the U.S. Armed Forces moved to an all-volunteer military except for draftees called up through the end of 1972.
