The 1913 Epsom Derby, sometimes referred to as "The Suffragette Derby", was a horse race which took place at Epsom Downs on 4 June 1913. It was the 134th running of the Derby. The race was won, controversially, by Aboyeur at record 100–1 odds. The winner was ridden by Edwin Piper and trained by Alan Cunliffe.
The race was overshadowed by the death of suffragette Emily Davison, who was killed when she ran out in front of King George V's horse, Anmer. The horse struck Davison as she tried to grab the horse's reins; the injuries she received proved fatal as she died four days later. Davison was a militant suffragette and a member of the Women's Social and Political Union (WSPU), she campaigned throughout her life for votes for women in the United Kingdom.
The race was attended by an estimated 500,000 people, including the King and Queen.[1]
