On September 16, 1919, the American Legion was incorporated by an act of US Congress. Here is a history of many of the things the group has worked on. From the article:
History
The American Legion was chartered by Congress in 1919 as a patriotic veterans organization. Focusing on service to veterans, servicemembers and communities, the Legion evolved from a group of war-weary veterans of World War I into one of the most influential nonprofit groups in the United States. Membership swiftly grew to over 1 million, and local posts sprang up across the country. Today, membership stands at over 2 million in more than 13,000 posts worldwide. The posts are organized into 55 departments: one each for the 50 states, along with the District of Columbia, Puerto Rico, France, Mexico and the Philippines.
