On June 8th 1913, the suffragette Emily Davison jumped in front of Anmer, the King’s horse, at the Epsom Derby which led to her death (which happened days after this was published in the tabloid The Daily Sketch, seen above). Her action was meant to bring support and attention to the suffragette movement and it made her a type of martyr for the movement. Historically 1913 derby is not remembered as the “most wonderful” derby,as the paper suggests, but of Emily Davison’s actions, for the right to vote for women.
There is actual footage of the incident which can be seen here.
