Reference: TB Heritage.com ---The story of the Byerley Turk begins at the seige of Buda in Hungary in 1688, when a fine brown charger was taken from a captured Turkish officer by Captain Robert Byerley of the Sixth Dragoon Guards under King William III of Orange. The horse was believed to be about eight years old at the time, placing his year of birth at around 1679. The stallion served as Byerleys war horse when he was dispatched to Ireland in 1689 during King Williams War. In 1690, public records show a race meeting was held in the spring at Down Royal in Northern Ireland, at which the top prize, the Silver Bell, was won by Captain Byerleys charger. Later that same year, the stallion was used during the Battle of the Boyne, July 12, 1690, versus the forces of King James II. [His biography up to this point closely parallels that of the Lister Turk, also captured at the seige of Buda and taken to Ireland to serve in the Battle of the Boyne.]
The Byerley Turk first entered stud in England, at the family seat at Middridge Grange, County Durham and later stood at Byerleys Goldsborough Hall, near Knaresborough, in Yorkshire. It is said that he covered few mares during either period of his stud career, which makes the results even more remarkable. He was known to be at stud as late as 1701, the year he sired Basto (foaled in 1702). Its possible that his remains are buried somewhere on the Goldsborough estate. (Deceased in 1706)

The other two were the Darley Arabian (Manak), imported to England in 1704, and the Godolphin Arabian (Scham), imported to England in 1729.
