The American Saddlebred Horse Association was formed in 1891, then called the National Saddle Horse Breeders Association (NSHBA). Private individuals had produced studbooks for other breeds, such as the Morgan, as early as 1857, but the NSHBA was the first national association for an American-developed breed of horse. A member of Morgan's Raiders, General John Breckinridge Castleman, was instrumental in forming the NSHBA. In 1899, the organization name was changed to the American Saddle Horse Breeders Association, clarifying the breed's name as the "American Saddle Horse," not simply "Saddle Horse."
