Why is the Derby so-called?
In 1779, Edward Smith-Stanley, 12th Earl of Derby founded a sweepstakes race, for three-year-old thoroughbred fillies, to be run over a mile-and-a-half on Epsom Downs. He called it the Oaks Stakes, after his nearby residence, known as ‘The Oaks’ or, historically, as ‘Lambert’s Oaks’, in Carshalton. Derby won the inaugural running of the Oaks Stakes with his own horse, Bridget, and subsequently celebrated with friends, who included Sir Charles Bunbury, Chairman of the Jockey Club.
Together, the pair co-founded another sweepstakes race, for three-year-old colts and fillies. Legend has it that they tossed a coin to decide on the name of the race but, in any event, the inaugural ‘Derby Stakes’ was run, over a straight mile, on Epsom Downs on May 4, 1780. Bunbury had some consolation insofar as he won the race, with Diomed, and collected the princely sum of £1,065 15s. The Derby Stakes was run over a mile until 1784, when the distance was extended to a mile-and-a-half and the sweeping, downhill turn into Tattenham Corner was introduced.
