Byerley Turk
![](http://upload.wikimedia.org/wikipedia/commons/thumb/e/ec/Byerly_Turk.jpg/220px-Byerly_Turk.jpg)
The Byerley Turk (c. 1680 – c. 1703[1]), also spelled Byerly Turk, was the earliest of three stallions that were the founders of the modern Thoroughbred horse racing bloodstock (the other two are the Godolphin Arabian and the Darley Arabian).[2][3]
Background
The biographical details of the stallion are the subject of much speculation. The entry in the General Stud Book simply states: "BYERLY TURK, was Captain Byerly's [sic] charger in Ireland, in King William's wars (1689, &c.)."[4] As for his earlier history, the most popular theory is that the horse was captured at the Battle of Buda (1686) along with the Lister Turk, who was brought to England by the Duke of Berwick. Other sources speculate he was one of three Turkish stallions captured at the Battle of Vienna.[5] It is even possible he was bred in England from previously imported stock.[6] He was definitely the war horse and cavalry mount of Captain Robert Byerley, who was dispatched to Ireland in 1689 during King William's War and saw further military service in the Battle of the Boyne. According to early records, Captain Byerley was nearly captured while reconnoitering the enemy, "owing his safety to the superior speed of his horse".[5]
As a general rule, the spelling of a name registered with the Jockey Club is considered definitive, even if it is an obvious error.[7] However, the original edition of the General Stud Book was compiled nearly a century after the fact (in 1791) and contains several errors that have been subsequently corrected. Most sources consider the correct spelling of the horse's name to follow the correct spelling of the owner's name, Byerley.[5]
The Byerley Turk was a dark brown or black[1] horse of unknown breeding, but described in historic accounts as an Arabian.[5] At the time, Turkish horses were described as descended from "those of Arabia or Persia", but stated that they were longer in the body and of a larger size.[8] He was described as a horse of elegance, courage and speed.[5] Many of his offspring were also noted to have been either bay or black.[9]
Stud record
In 1692, Captain Byerley married his cousin, Mary Wharton (sole heir to the estate of Goldsborough, near Knaresborough, North Yorkshire, England) and moved to live with her at her family home of Goldsborough Hall. After Byerley retired (as Colonel Byerley), the Byerley Turk retired to stud, first at Middridge Grange, then, from 1697, at Goldsborough Hall.[5] The Byerley Turk died there in 1703 and it is believed he is buried close to the Hall. Goldsborough Hall is now a private family home that offers accommodation, which includes the commemorative Byerley suite.[10]
He did not cover many well-bred mares,[11] but his most significant sons include:
![](http://upload.wikimedia.org/wikipedia/commons/thumb/d/d0/Crofts_Partner_%28GB%29.jpg/220px-Crofts_Partner_%28GB%29.jpg)
- Black Hearty, black colt born c. 1695, "a famous Horse of Sir George Fletcher"[5]
- Grasshopper or Bristol Grasshopper, c. 1695, won the Town Plate at Nottingham under 10 stone[5]
- Jigg, c. 1701, a bay colt of middling ability[9] who became the sire of Partner, a four-time leading sire. Partner sired Tartar, who was the sire of Herod (1738).[2] Herod founded one of the three sire lines from which all modern Thoroughbreds descend, the other lines being founded by Eclipse and Matchem.
- Basto, a nearly black colt born c. 1704, who won several match races from 1708 to 1710.[12] Basto sired Old Ebony, the foundation mare of family #5.[a]
The Byerley Turk also sired several highly influential daughters, most of whose names do not survive. They are generally classified by the female family that they belong to:
- Byerley Turk mare, a black or brown daughter out of Tarfollet Barb mare, through whom all modern members of family #1 descend.[9] Family 1 is estimated to account for 15% of all thoroughbreds, and has been divided into several sub-families for ease of reference. For example, family 1-k, the family of Frankel among many others, traces back through several branches to family 1-a, Bonny Lass, a grand-daughter of the Byerley Turk mare.[13] As of 2010, there were 33 Epsom Derby winners, 31 St. Leger winners, and 40 winners of The Oaks Stakes listed in family 1 as descendants of the Byerley Turk mare[14]
- Bowes' Byerley Turk mare, the "Dam of the Two True Blues", the taproot of family 3. Though not as widespread as family 1, many classic winners around the world trace back to family 3.[15] As of 2010, there were 25 Derby winners, 26 Oaks winners and 20 St Leger winners from family 3[16]
- The Byerley Turk mare out of Bustler Mare, the taproot of family 8, which has produced 7 Oaks winners, 11 Derby winners, and 15 St Leger winners including Nijinsky[17]
- The Byerley Turk mare that was the taproot of family 17, which has produced 2 Oaks and 3 St Leger winners
- The Byerley Turk mare that was the taproot of family 41[18][19]
Byerley Turk sire line

![](http://upload.wikimedia.org/wikipedia/commons/thumb/f/f1/Atlantic_%28horse%29.jpg/220px-Atlantic_%28horse%29.jpg)
The Byerley sire line persisted by producing a major sire every few generations, whose sons would create branches of their own. Most of these branches have died out over the course of time in the purebred Thoroughbred, but remain present in other horse breeds in which mares were bred to male descendants of the Byerley Turk. The line of descent to the present day is as follows:[20][21][22]
- The Byerley Turk (~1680) sired Jigg in 1705, who sired Partner in 1718, who sired Tartar in 1743, who sired Herod in 1758. Herod was the leading sire in Great Britain and Ireland from 1777 to 1784.
- Herod sired Highflyer in 1774, leading sire in Great Britain from 1785-1796. Highflyer sired Sir Peter Teazle, who was leading sire in Great Britain from 1799-1802, 1804-1809. Highflyer's line persisted for many generations, but died out by the mid-20th century.[23]
- Herod sired Florizel (1768), who sired Diomed (1777). Diomed would become a foundation sire of the American turf. In turn, Diomed sired Sir Archy, who was the first great "sire of sires" in the United States. A few generations later through Sir Archy's line came Lexington, who became the leading sire in North America sixteen times in the mid-19th century; his sire line died out in the late 20th century.[24][25][26][27]
![](http://upload.wikimedia.org/wikipedia/commons/3/30/Sultan_%28GB%29.jpg)
- Herod's line continued through Woodpecker, foaled in 1773, who sired Buzzard (1787). Buzzard founded several sire lines that flourished in the 19th century, most of which withered away in the 20th century.[28] Two lines through Buzzard survived into the 21st century, Castrel (1801), and Selim (1802). Castrel sired Pantaloon (1824), who sired Windhound (1847), who sired Thormanby (1857), who sired Atlantic (1871), who sired Le Sancy (1884), who sired Le Samaritain (1893), who sired Roi Herode (1904). Roi Herode’s son Royal Canopy (1914) sired Bonn Nuit (1934) who established a Show jumping dynasty that extended to the 21st century through champion show jumper Gem Twist, though that horse was a gelding. Buzzard's son Selim was leading sire of 1814. Selim produced a flourishing sire line, most of which died away by the mid 20th century.[29] Selim's sire line continued through Sultan, born in 1816. Sultan was leading sire 6 times.
![](http://upload.wikimedia.org/wikipedia/commons/thumb/5/53/Bay_Middleton.jpg/220px-Bay_Middleton.jpg)
- Sultan in turn sired Bay Middleton (1833), who was leading sire in 1844 and 1849. Bay Middleton sired several sire sons but most of his line died out by the middle of the 20th century.[30] Bay Middleton's sire line continued through The Flying Dutchman, born in 1846. The Flying Dutchman sired several sons whose lines gradually died out over the course of the 20th century. The Flying Dutchman's line continued through Dollar in 1860, who sired Androcles in 1870, who sired Cambyse in 1884, who sired Gardefeu in 1895, who sired Chouberski in 1902, who sired Bruleur in 1910. Bruleur sired Ksar in 1918.
![](http://upload.wikimedia.org/wikipedia/commons/thumb/5/53/KSAR_%28G._Stern%29%2C_m._al._3_ans%2C_par_Br%C3%BBleur_et_Kizil_Kourgan%2C_gagnant%2C_cette_ann%C3%A9e%2C_des_Prix_Hocquart%2C_Lupin%2C_du_Jockey_Club%2C_Royal_Oak%2C_et_de_l%27Arc_de_Triomphe%2C_au_tolal_de_931.575_francs_d%27argent_public.jpg/220px-thumbnail.jpg)
- Ksar was a two-time winner of the Arc de Triomphe and the leading sire in France for 1931. Ksar sired Tourbillon in 1928. Tourbillon was three-time leading sire in France. As recently as the 1982 stallion register, four sons of Tourbillon were known to have active stallions (Ambiorix, Coaraze, Djebel, and Timor).[31] Tourbillon's sire line has not had a stallion in the top 100 turf horses as recently as 2018.[32]
- Djebel sired My Babu, who also won the 2000 Guineas. The My Babu sire line persisted for several generations, leading to Cirrus des Aigles, a Group 1 winner as late as 2014. Unfortunately, Cirrus des Aigles was gelded so the My Babu sire line is on the brink of extinction, though as of 2023, sire Bulleton (Australia, 2003) still serves mares in N.S.W., Australia.[33] His sire is Rubiton, by Century, by Better Boy (Ireland, 1951). Better Boy was 4-time Champion Sire in Australia (1965–66, 1970–71, 1971–72 and 1976–77), Sired 35 stakes winners and was Champion Broodmare Sire in Australia 1978-79.[34] In addition, Japanese horse racing fans have attempted to keep the sire line of Tokai Teio (who is a descendant of My Babu through his son, Milesian)[35] alive by means of crowdfunding, through his son, Quite Fine.[36][37]
- Djebel also sired Clarion, born in 1944, who, though less successful than My Babu on the track, is the best hope for the survival of the Byerley Turk sire line. Clarion sired Klairon in 1952, whose son Luthier would lead the french sire list four times. Luthier's sire line continued for a few generations but seems to have died out. Klairon also sired Lorenzaccio in 1965, who in turn sired Ahonoora in 1975. Ahonoora proved a very successful sire, with offspring including: Don't Forget Me (2000 Guineas), Dr Devious (Epsom Derby), and Indian Ridge. The Indian Ridge line has hopes primarily through the lineage of six sons: Compton Place (1994), Indian Rocket (1994), Namid (1996), Indian Haven (2000), Linngari (2002), and Luck Money (2005). Pearl Secret (son of Compton Place) is at stud in England, Captain Chop (son of Indian Rocket) is at stud in France, Linngari is at stud in South Africa, Total Gallery (son of Namid) is at stud in India, Luck Money is at stud in South America, while Indian Haven was at stud in Ireland until his death in 2023.[34][38][39][40][41][42][43][44][45]
Thus, the continuation of the Byerley Turk sire line through Herod in the purebred Thoroughbred now largely depends on the descendants of Djebel, primarily through six descendants of his son Clarion (Captain Chop, Indian Haven, Linngari, Luck Money, Pearl Secret, and Total Gallary, via the Indian Ridge line),[34][39][40][41] and secondarily through two descendants of his son My Babu (Bulleton via the Better Boy line, and Quite Fine via the Milesian line).[33][36][37][35][42][43][45]
- Continuation of direct sire line through reporting error
Recent research from 2017[46] and 2019[47] has brought into question the lineage of the sire Galopin. The research suggests that Galopin descends, not from the Darley Arabian sire line, but from the Byerley Turk. This is due to the descendants of Galopin possessing the Y chromosome Tb-oB1 rather than Tb-d, which is found in descendants of the Darley Arabian.[48] This line of descent, which is a rare line via sire St. Simon (1881 – 1908), was found to exist as recently as 2023 in Saudi Arabia, from the sons of Pleasant Colony.[25]
- Contining influence other than direct sire line
Focusing on the sire line may underestimate the ongoing influence of the Byerley Turk; detailed pedigree analysis shows that he has a higher percentage of blood in the modern Thoroughbred than either of his fellow foundation sires through other lines of descent.[31] Thormanby (1857–1875), a Byerley Turk descendant who sired almost 100 stakes winners, is present in the pedigrees of almost all modern Thoroughbreds through his daughter, Rouge Rose, who produced the Epsom Derby winner Bend Or (Darley Arabian line).[49][50]
Byerley Turk line in crossbreds
- United States
The Byerley Turk sire line has carried on in other horse breeds through his direct male descendants such as Diomed (American Quarter Horse and Standardbred),[51][52][53][54] Denmark (American Saddlebred),[55] and Justin Morgan (Morgan horse).[56] Denmark, Justin Morgan, and Sir Archy (son of Diomed),[57] are key foundation sires for their breeds.[55][56]

The Kisbér Félvér of Hungary has a direct sire line link to the Byerley Turk. The lineage can be traced to the German-born Thoroughbred stallion Fenék (b. 1883), who was by the British stallion Buccaneer - a descendant of Herod (b. 1758) through Herod's son, Highflyer (b. 1774) - out of the mare Hélène Triomphante, of the Godolphin Arabian line. Fenék was transferred to the Kisbér Stud in Hungary in 1894, where he had a stud fee of £30 for foreign-owned mares, and £20 for Hungarian-owned mares.[58][59]
In the Trakehner, the Byerley Turk also had a major influence. Of the English Thoroughbred stallions who stood at the stud at Trakehnen, some were Byerley Turk sire line descendants, including Snyders (b. 1833), a male-line descendant of Herod (b. 1758); and Perfectionist, a member of the disputed Galopin line. The German Thoroughbred stallion Lehnsherr (b. 1927), a Byerley Turk male-line descendant through Atlantic (1871–1891) through his son, the French Thoroughbred stallion Le Sancy (b. 1884), would also become an influential sire in the Trakehner breed.[60] Chamant (b. 1874), another Byerley Turk descendant, also influenced the Trakehner and the Westphalian.[61]
The Byerley Turk sire line also lives on in Poland through the Anglo-Arabian stallion Ramzes (b. 1937), who was sired by the gray Belgian Thoroughbred stallion Rittersporn (b. 1917) out of the Shagya Arabian mare Jordi. Rittersporn was a male-line descendant of the English Thoroughbred racing stallion Herod (b. 1758) through Herod's son, Woodpecker (b. 1773), and Woodpecker's son, Buzzard (b. 1787). Ramzes was an influential warmblood sire of show jumping and dressage horses who stood at various studs, including the Janów Podlaski Stud Farm in Poland, and would go on to have a strong influence on the Westphalian, Holsteiner, and other German warmblood breeds.[62]
The Grand Prix and 1996 Olympic dressage team stallion Rubinstein I (1986 – 2000), a Westphalian, was one of Ramzes' most influential descendants among German warmblood and sport horse breeders, siring 89 state premium mares and 66 approved stallions.[63] Rubinstein I sired over 400 mares in different German warmblood registries, as well as numerous sons recognized as Oldenburg and Hanoverian stallions.[64] The performances of his get placed him 4th on the dressage index for older stallions.[65]
Another influential Hanoverian stallion of the Byerley Turk line includes Bolero (1975 – 1987), by the Thoroughbred stallion Black Sky (b. 1966) of the Djebel line, out of the Hanoverian/Thoroughbred mare Baronesse (b. 1970).[66] One of Bolero's best-known female descendants was the Hanoverian mare Brentina (1991 – 2021),[67] the first American horse to take the FEI World Cup Final in 2003; made the shortlist for the 2004 Summer Olympics; and was named to the 2006 World Equestrian Games team, earning a bronze medal for the United States.[68]
