Where does reining originate?

Reining originated in the United States, specifically from the traditions of cattle herding and ranching in the American West. It evolved from the working practices of ranch horses, which were trained to perform various maneuvers to help manage cattle. The sport was formalized in the mid-20th century, gaining popularity through competitions and becoming a recognized discipline within the American Quarter Horse Association. Today, reining is also an international sport, celebrated for its emphasis on precision and control.
