The Society of the Cincinnati is the nation's oldest patriotic organization, founded in 1783 by Revolutionary War officers to promote the memory of the achievement of American independence. Now in its third century, the Society has been perpetuated by male descendants of the officers as a nonprofit historical and educational organization that promotes public interest in the American Revolution through its library and museum collections, exhibitions, research, publications, educational outreach, and other activities. The Society also maintains its historic fellowship of members, which currently numbers more than 3,900 men.

Many of these activities take place at the Society's headquarters in Washington, D.C., Anderson House, a National Historic Landmark that was completed in 1905 for Larz and Isabel Anderson. Upon Larz Anderson's death in 1937, his wife gave the house to the Society, of which he had been a devoted member. Since 1939, Anderson House has been open to the public as a historic house museum where visitors can see the Andersons' collections and attend the Society's exhibitions and other events. Anderson House also houses the Society's library, a 45,000-item research collection of early printed and manuscript materials and modern reference sources focused on the era of the American Revolution, the art of war in the eighteenth century, and the history of the Society.

Our staff members are available as experts on a variety of topics including the American Revolution; George and Martha Washington; the history of the Society of the Cincinnati; Washington, D.C., during the Gilded Age; and eighteenth-century books, manuscripts, and portraits.
