Records of the Society of the Cincinnati from its founding in 1783 to the present. The early records, generally covering the period from 1783 through the early 1930s, have a finding aid available and are fully open to research. Highlights of the early records include the signed Institution of the Society, early minute books, and correspondence of prominent original members such as Henry Knox, Pierre L'Enfant, and George Washington. Highlights of the modern archival collections include photographs of Society meetings from the late 19th century onwards.
The archives provide a wealth of information on the history of the Society and related topics in American history, such as compensation for Revolutionary War veterans and widows, public views of military officers and hereditary organizations, early Franco-American relations, and nineteenth- and twentieth-century remembrances of the Revolutionary War era.
