Nasrullah (March 2, 1940 – May 26, 1959) was a Thoroughbred racehorse that was bred in Ireland and trained in the United Kingdom before becoming a champion sire in both Europe and North America. As a two-year-old, he won the Coventry Stakes and finished second in the Middle Park Stakes, ending the year as the top-rated colt of his generation. In the following season, he became increasingly difficult to manage, and his temperament compromised his racing career. He was the beaten favourite in the 2,000 Guineas and finished a close third in the Derby Stakes before winning the Champion Stakes. As a breeding stallion he stood in England, Ireland, and the United States and had great success in each location.
Nasrullah was a big, handsome bay horse with a white star, bred in Ireland by his owner the Aga Khan. He was sired by Nearco, an undefeated Italian racehorse that became one of the most important stallions of the 20th century. Apart from numerous major winners, he sired the influential stallions Nearctic and Royal Charger. His dam, Mumtaz Begum, was a daughter of the outstanding racehorse and broodmare Mumtaz Mahaland became an influential broodmare in her own right: her other descendants have included Royal Charger, Habibti, Octagonal, Oh So Sharp, and Risen Star.
The Aga Khan sent Nasrullah into training with Frank Butters at his Fitzroy House stable in Newmarket. Because of the restrictions imposed as a result of the Second World War, many British races were adapted both in distance and venue, and Nasrullah's entire racing career was confined to Newmarket Racecourse.
On his racecourse debut, Nasrullah finished third in the Wilburton Stakes, but was then moved up in class and contested the Coventry Stakes (usually run at Royal Ascot) on 12 June. Ridden by the champion jockey Gordon Richards, he won at odds of 7/4, beating the future Derby winner Straight Deal. In July, he won the Great Bradley Stakes, beating a single opponent.
Nasrullah was then rested until the autumn, when he ran in Britain's most prestigious race for two-year-olds, the six-furlong Middle Park Stakes. In a closely run contest, he finished second, beaten a neck by the filly Ribbon.
In the Free Handicap, a rating of the season's best two-year-olds, Nasrullah was given a weight of 136 lb, making him the top-rated colt, a pound behind the filly Lady Sybil.
Before the start of the 1943 season, bookmakers offered prices for the season's leading races despite wartime restrictions, and Nasrullah was made the early favourite for the Derby ahead of his stable companion Umiddad.On his first appearance as a three-year-old, Nasrullah won the Chatteris Stakes easily, but his conduct before the race caused concern. He was extremely unwilling to leave the pre-race paddock and gave Richards several problems on the way to the start. On his next appearance, he was fitted with blinkers when he was started 13/8 favourite for the 2,000 Guineas. Despite his headgear, he was again reluctant to go down to the start, and after leading for five furlongs, he faded to finish fourth of the 19 runners behind the outsider Kingsway.
The "New" Derby of 1943 was run over Newmarket's July Course, and Nasrullah started at odds of 9/1 in a field of 23 runners. Richards, who had the choice of several rides, elected to ride Nasrullah despite his bad behaviour and that he had been labeled a "rogue".Richards struggled to keep the colt on a straight course, but eventually succeeded, and Nasrullah looked the likely winner when he took the lead in the last quarter-mile. In the closing stages, however, he was overtaken and finished third to Straight Deal and Umiddad. In August, Nasrullah went some way towards restoring his reputation when he won the Cavenham Stakes, although Richards had to "persuade" the colt to keep going when he began to idle after taking the lead.
In autumn, Nasrullah was disappointing in the "New St Leger" over 14 furlongs, in which he finished sixth of the 12 runners behind the filly Herringbone. On his final appearance of the year, Nasrullah showed his best form as he won the 10-furlong Champion Stakes from Kingsway and Umiddad in what was described as "the smoothest race of his career".
In 1944, he was purchased by the bloodstock agent Bertie Kerr. Kerr kept him for three weeks before selling him for 19,000 guineas to Joseph McGrath, who subsequently stabled him at the Brownstown Stud in County Kildare. This deal was allegedly done over an afternoon cup of tea at Bewley's in Westmoreland Street.Nasrullah was an immediate success as a breeding stallion, and in his six seasons, his fee rose from 198 guineas to 500 guineas. He was champion sire in 1951. The best of his European progeny included:
In 1950, Nasrullah was sold for $370,000 to Arthur B. Hancock, Jr. He was exported to stand at stud in the United States at Hancock's Claiborne Farm in Paris, Kentucky. Nasrullah became one of the most important North American sires of the 20th century, leading the sire list five times. Among his American progeny were:
Nasrullah died on May 26, 1959. He is buried at Claiborne Farm.

He was one of the best British two-year-olds of 1874, winning his first three races before sustaining the only defeat of his career in the Middle Park Plate.

He was unbeaten in five races in 1919, including the Molecomb Stakes, Champagne Stakes, and Middle Park Stakes, and was the highest-rated two-year-old in Britain by a record margin. In the following year he had enough stamina to win the Classic 2000 Guineas over a mile, but failed to stay when unplaced in both The Derby and the Eclipse Stakes. He then returned to sprinting and won his remaining two races of 1920 and all four in 1921.

His most important success came in June 1943 when he won the “New Derby”, a substitute race for The Derby run on the July Course at Newmarket. During the Second World War many racecourses were closed either for safety reasons or for military use, with Epsom Downs Racecourse being used as the location for an anti-aircraft battery. Straight Deal was retired after finishing third in the “New St Leger” later that year and went on to become a successful stallion.
Big Game (1939–1963) was a British Thoroughbred racehorse and sire. In a career that lasted from April 1941 to October 1942, the colt, who was owned by King George VI, ran nine times and won eight races. He was the best British two-year-old colt of his generation in 1941 when he was unbeaten in five starts. Two further wins the following spring including the 2000 Guineas at Newmarket took his unbeaten run to seven, but he suffered his first defeat when odds-on favourite for the wartime "New Derby". He won his only other race in the Champion Stakes before being retired to stud. Big Game's royal connections and racecourse success made him one of the most popular horses of his time.
