Where did the American Quarter Horses come from?

The American Quarter Horse is one of the few breeds of horses that has it's origins in America. Wild ferel horses of the American plains breed to European imports and mixed in some Thoroughbred blood made the beginings of the Quarter Horse breed. The King Ranch in Texas had much to do with the breed standard. With 3 stallions (QH) and a Thoroughbred stallion named Three Bars the Quarter Horse was official. Now the AQHA registers more horses than any other breed in the world.
