Colonial Spanish horse is a term for a group ofhorse breed andferal populations descended from the originalIberian horse stock brought fromSpain to theAmericas.[1] The ancestral type from which these horses descend was a product of the horse populations that blended between theIberian horse and the North AfricanBarb.[2] The term encompasses many strains or breeds now found primarily inNorth America. Thestatus of the Colonial Spanish horse is considered threatened overall with seven individual strains specifically identified.[3][a] The horses are registered by severalentities.
The Colonial Spanish horse, a general classification popularized by D. Philip Sponenberg, is not synonymous with theSpanish Mustang, the name given to a specificstandardized breed derived from the first concerted effort of conservationists in the United States to preserve horses of Colonial Spanish Type.[1] Colonial Spanish horse blood markers have been found in somemustang populations. Small groups of horses of Colonial Spanish horse type have been located in various groups of ranch-bred,mission, andNative American horses, mostly among those in private ownership.[1]
Colonial Spanish horses are generally small; the usual height is around 14 hands (56 inches, 142 cm), and most vary from 13.2 to 14 hands (54 to 56 inches, 137 to 142 cm). Weight varies with height, but most are around 700 to 800 pounds (320 to 360 kg). Their heads vary somewhat between long, finely made to shorter and deeper, generally having straight to concave (rarely slightly convex) foreheads and a nose that is straight or slightly convex. The muzzle is usually very fine, and from the side the upper lip is usually longer than the lower, although the teeth meet evenly. Nostrils are usually small and crescent shaped. They typically have narrow but deep chests, with the front legs leaving the body fairly close together. When viewed from the front, the front legs join the chest in an "A" shape rather than straight across as in most other modern breeds that have wider chests. The withers are usually sharp instead of low and meaty. The croup is sloped, and the tail is characteristically set low on the body. From the rear view they are usually "rafter hipped" meaning the muscling of the hip tapers up so the backbone is the highest point. Hooves are small and upright rather than flat.[4]
Horses first returned to the Americas with theconquistadors, beginning withColumbus, who imported horses fromSpain to theWest Indies on his second voyage in 1493.[5] Domesticated horses came to the mainland with the arrival ofCortés in 1519.[6] By 1525, Cortés had imported enough horses to create a nucleus of horse-breeding in Mexico.[7] Horses arrived in South America beginning in 1531, and by 1538 there were horses in Florida. From these origins, horses spread throughout the Americas. By one estimate there were at least 10,000 free-roaming horses in Mexico by 1553.[2]
In 2010, the Colonial Spanish mustang was voted the official state horse of North Carolina.[8]
Manygaited horse andstock horse breeds in the United States descend from Spanish horses,[4] but only a few bloodlines are considered to be near-pure descendants of original Spanish stock. Though many are described ashorse breeds, it can be debated they are separate breeds or multiple strains of a single large breed. The Livestock Conservancy lists them as one breed, but also calls them "a group of closely related breeds"[4] Various bloodlines or groups of Colonial Spanish horses are registered a number of different Associations.[1]
While some bands of modernmustangs have evidence of ancestry from the original Spanish imports, genetic analysis indicates that many free-ranging horses in theGreat Basin descend from later breeds of draft horse, cavalry mounts, and othersaddle horses.[9] Where they have been found to have descended from the original Spanish horses, theBureau of Land Management (BLM) and other agencies attempt to preserve them.[1] Blood typing, along withphenotype and historical documentation have been used to confirm significant Spanish ancestry of a few BLM managed herds.[10] In 1985, the BLM awarded a grant to the University of California, Davis, to conduct a three-year study on mustang genetics, including the percentage of original Spanish blood.[11]Ann T. Bowling and R. W. Touchberry did not find much evidence of Spanish genetics in the Great Basin horses tested, but follow up work by Gus Cothran, then ofUniversity of Kentucky, carried on the study and found Spanish markers in the Pryor Mountain and Cerbat herds outside the Great Basin, and Sulphur Springs herd within it,[12] later confirming the findings for the Sulphur Springs herd throughmtDNA sequencing analysis.[2][b] Some breeders and horse associations have used blood typing results to prove or disprove horses being of Spanish ancestry, but some horses of Spanish phenotype may not carry the expected Iberian blood markers. Conversely, some horses that lack Spanish type, such as certain strains of theAmerican Quarter Horse, may have blood markers but not the proper phenotype.[1]
Colonial Spanish horses include numerous strains, which may be feral populations or standardized breeds:
A number of breeds in Latin America with Iberian DNA markers are of Spanish type and origin.[2][c] Many of these breeds come from different North Americanfoundation bloodstock,[1] and some havehaplotypes not found in North America.[2]
