This paper explores the relationship between equestrianism and sport coaching at the turn of the twentieth century. Women were avid and admired participants in fox hunting and other mounted field sports by the mid-nineteenth century, and they expanded on this success by attaining positions of leadership in many hunts throughout Britain, specifically as Masters of Hounds. Women thus attained positions of supreme authority over, and therefore equality with, peers of both sexes well before they obtained wartime jobs after 1914 or achieved the vote in 1918. As Masters, women were teachers, trainers, mentors, managers and bosses; they were some of the first female sport coaches, advancing and revolutionising sport in a variety of ways, though such participation has yet to be fully studied or recognised. By examining the position of Master of Hounds and women’s involvement in these leadership roles, we can see how advances in sport shaped changes in social, cultural, and gender perceptions before and after the First World War.
