United States National Cemetery System

The United States National Cemetery System is a system of 164 cemeteries in the United States and its territories. The authority to create military burial places came during the American Civil War, in an act passed by the U.S. Congress on July 17, 1862. By the end of 1862, 12 national cemeteries had been established. Two of the nation's most iconic military cemeteries, Arlington National Cemetery and Gettysburg National Cemetery were established in 1864 and 1863, respectively.
