Icelandic horse

The Icelandic horse (Icelandic: íslenski hesturinn [ˈistlɛnscɪ ˈhɛstʏrɪn]), or Icelandic, is a breed of horse developed in Iceland. Although the horses are smaller (at times pony-sized) than other breeds, most registries for the Icelandic refer to it as a horse. The breed is long-lived and hardy, owing to the ruggedness of its home country. In their native Iceland they have few afflictions or diseases, thus national laws are in place preventing foreign-born horses from being imported into the country, while exported animals are not permitted to return. In addition to the gaits of walk, trot, and canter/gallop, typical of other horse breeds, many Icelandic horses can also do the tölt (ambling gait) and the flying pace. The only breed of horse in Iceland, the Icelandic is also popular internationally, and sizable populations exist in Europe and North America. The breed is still used for traditional sheepherding work in its native country, as well as for leisure, showing, and racing.

Developed from ponies brought to Iceland by Norse settlers in the 9th and 10th centuries, the breed is mentioned in various documents from throughout Icelandic history; an early reference to a named-horse appears in the 12th century. Horses were venerated in Germanic religion, a custom brought to Iceland by the country's earliest settlers. Centuries of selective breeding have developed the Icelandic horse into its modern physical form, with natural selection having also played a role in overall hardiness and disease resistance; the harsh Icelandic climate likely eliminated many weaker horses early on due to exposure and malnourishment, with the strongest passing on their genes. In the 1780s, much of the breed was wiped out in the aftermath of a volcanic eruption at Laki. The first breed society for the Icelandic horse was created in Iceland in 1904, and the breed is represented by organizations in 22 different nations as of 2024, organised under a parent association, the International Federation of Icelandic Horse Associations.
