The American Legion is a congressionally chartered mutual- aid veterans organization of the United States armed forces founded to benefit those veterans who served during a wartime period as defined by the U.S. Congress. The American Legion was founded in 1919 by veterans returning from Europe after World War I, and was later chartered under Title 36 of the United States Code. The organization is headquartered in Indianapolis, Indiana and also has offices in Washington D.C. The group has nearly 3 million members in over 14,000 Posts worldwide. In addition to organizing commemorative events and volunteer veteran support activities, the American Legion is active in U.S. politics. While its primary political activity is lobbying on the behalf of the interests of veterans and service members, including support for veterans benefits such as pensions and the Veterans Affairs hospital system, it has also been involved in more general political issues.
