Explain the draft, why it might be used, and the last time it was enforced in the United States.

A process of selecting people from a specific group to serve in the military. Conscription is the mandatory enlistment in a country's armed forces, and is sometimes referred to as "the draft." The origins of military conscription date back thousands of years to ancient Mesopotamia, but the first modern draft occurred during the French Revolution in the 1790s. The United States instituted conscription during the Civil War, which led to a series of bloody draft riots. Resistance to the draft, as managed by the Selective Service in the United States, reached a historic peak during the Vietnam War.
