In 1913, the British suffragette Emily Wilding Davison was killed when she ran onto the race course at Epsom Downs during the running of the Derby. Davison's goals are unclear, but she was immediately hailed as a martyr to the women's cause by her comrades in the Women's Social and Political Union. Others denounced her as a suicidal fanatic. This article evaluates Davison's death by examining the WSPU's emphasis on self-sacrifice, the actions of other women who risked their lives for (...) the right to vote, and Davison's political writings and activities. Combined, these features of the militant suffrage movement support the WSPU's identification of Davison as a martyr. They also raise questions about the ideological integrity of the concept of secular martyrdom. (shrink)
