of the Goryeo Dynasty, recorded in 1073 A.D. (the 27th year of King Moonjong’s reign), states that an excellent steed was presented to the king from Jeju, which indicates Jeju has a long history of breeding horses. Systematic management of Jeju horses at a national level started in 1276 when a state-run ranch, Tamna Ranch, was constructed to accommodate 160 horses imported from Mongolia. According to another record, Jeju continued to import Mongolian horses for more than a century, until 1374. In the ancient times, Jeju provided horses upon the central government’s request, and bred approximately 20,000 horses. Starting in the 1960s, the usability of horses decreased as other means of transportation developed. In addition, the Korea Racing Authority introduced other breeds, such as the Anglo-Arabian and the Thoroughbred in late 1970s in order to produce race horses. Some of the foreign-bred stallions were used to create cross-breed horses, which contributed to the decreased number of native Jeju horses. In mid 1980s, the population of the Jeju horse dropped to approximately 1,200. In 1986, the central government designated the horse as Natural Monument No. 347, named ‘Jeju Horse of Jeju,’ to prevent it from extinction and to preserve its breeds as state-designated cultural properties. Currently, more than 150 native Jeju horses are being raised within a protection area. In 2000, the government appointed the Jeju Stockbreeding Promotion Institute as a designated agency to register and breed Jeju horses. It also established the Rules on the Registration and Management of Jeju Horses to maintain their pedigrees. An electronic chip is implanted into a new-born foal for identification. To confirm the pedigree, an accreditation certificate is issued after identifying the relationship between the parent horses and the foal using paternity tests recommended by the International Society of Animal Genetics. The pedigree-related information on Jeju horses is offered via the Jeju Horse Database System. References Kang, Min-soo (1999). “Jeju’s Jorang Horse”.
