The Caspian horse derives its name from the Caspian Sea region of northern Iran where the breed was rediscovered in 1965 after being thought extinct for over a thousand years. Known simply as "Caspian" in most contexts, the breed is sometimes called "Caspian pony" due to its height below 14.2 hands, though breed enthusiasts often prefer "Caspian horse" emphasizing the breed's horse-type characteristics rather than typical pony traits. Historical references suggest these horses may be descendants of ancient Persian horses depicted in artwork from Persepolis and other archaeological sites dating to 3000 BCE, though definitive genetic proof of this ancestry remains elusive.
The Caspian Horse Society, established in the 1970s following the breed's rediscovery, maintains the international studbook and registry standards preserving this rare breed. Multiple national registries exist including the Caspian Horse Society of the Americas, European registries, and organizations in Australia and New Zealand, all working cooperatively to maintain genetic records and promote responsible breeding of the limited global population. Registry standards emphasize preservation of the breed's distinctive characteristics including refined conformation, specific skeletal features distinguishing Caspians from other small horse breeds, and temperament qualities making them suitable for work with children.
The breed's rediscovery story is remarkable: American researcher Louise Firouz, living in Iran, encountered small horses in remote mountain villages near the Caspian Sea in 1965 that matched descriptions of ancient Persian horses from historical texts and artwork. Recognizing their potential significance, she began studying and preserving these horses, eventually establishing that they possessed unique skeletal characteristics and other features suggesting they represented an ancient, distinct breed rather than simply small local horses. This discovery sparked international interest in Caspian preservation, with breeding programs established worldwide ensuring the breed's survival despite political upheaval in Iran and the challenges inherent in maintaining very small populations.
