Union veterans in 1915 at the G.A.R. Post No. 522 in Yorkville, Illinois. GAR posts were all over the northern states and there was a counterpart organization for Confederate vetreans. The veterans groups of the 20th Century were led by the American Legion, Veterans of Foreign Wars, AMVETS, and other groups. Even today in places such as Virginia, there are Blue and Gray American Legion posts in memory of the times when veterans were organized by their Civil War loyalties. The Grand Army of the Republic was founded in 1868 in Decatur, Illinois by Dr. Benjamin Stephenson and at its zenith in the 1880s it had about 400,000 members or about one-third of all Union Army veterans.
