Does suffragette Emily Davison qualify for the title I've given her? The incident is shown in the video starting a bit before the six-minute mark.
She is best known for stepping in front of King George V's horse Anmer at the Epsom Derby on 4 June 1913, sustaining injuries that resulted in her death four days later....
Modern historians agree that Davison was trying to disturb the Derby in order to draw attention to her cause, rather than to commit suicide, and 2013 analysis of newsreel has supported the idea that Davison was reaching up to attach a scarf to the bridle of the King's horse. Analysis of newsreel also indicated that her position before she stepped out onto the track would have given her a clear view of the oncoming race, further countering the belief that she ran out in a haphazard way to kill herself.
I never did understand why cows and beauty contests are often linked. It's probably a throwback to ancient pagan fertility rites. Below are the six young women who hoped to become the 1975 Kern County Cattle Princess. I don't know who won.
