Shergar

Shergar (1978 - unknown) was an acclaimed Irish racehorse, and winner of the 1981 Epsom Derby by a record 10 lengths, the longest winning margin in the race's 226-year history. This victory earned him a spot in The Observer newspaper's 100 Most Memorable Sporting Moments of the Twentieth Century. A bay colt with a distinctive white blaze, Shergar was named European Horse of the Year in 1981 and was retired from racing that September.

Two years later, on 8 February 1983, he was stolen from the Ballymany Stud, near The Curragh in County Kildare, Ireland by masked gunmen with the body never being discovered. The incident has been the inspiration for several books, documentaries, and a film.
