The W.T. Waggoner Estate and King Ranch have been breeding American Quarter Horses for 100 years.

The American Quarter Horse Association is proud to recognize two historic Texas ranches that have been breeding American Quarter Horses for 100 consecutive years: W.T. Waggoner Estate and the King Ranch. Even though the Association and its registry were founded in 1940, these two ranches already had horse herds, several of which were inspected and admitted for registration with AQHA.
