The Ohio Historical Society is a non-profit organization incorporated in 1885 as The Ohio State Archaeological and Historical Society "to promote a knowledge of archaeology and history, especially in Ohio". The society exists to interpret, preserve, collect, and make available evidence of the past, and to provide leadership on furthering knowledge, understanding, and appreciation of the prehistory and history of Ohio and of the broader cultural and natural environments of which Ohio is a part. Its predecessor was founded by Brig. Gen. Roeliff Brinkerhoff in 1875. That society became dormant, and was revived at the urging of Governor George Hoadly in 1885.
