Emily Davies was a central figure in the mid-Victorian women's movement. Formidably intelligent, fiercely determined, and an indefatigable campaigner and organiser, the socially and politically conservative Davies directed the first campaign for female suffrage in 1866-7. She was one of the first women elected to public office in 1870, campaigned successfully for the admission of girls to school leaving examinations, played a significant part in the reform of girls' secondary school provision, and established Girton College, Cambridge, Britain's first university-level college for women.This book combines the first scholarly biography of Davies with a radically new account of the mid-Victorian women's movement. From the late 1850s to the mid-1870s and through the life, work, and writing of Davies, the book traces the growth, influence, and division of the movement, including its institutional origins; its social, political, religious and intellectual allegiances; and its relation to other major social and intellectual developments. Drawing on Davies' published correspondence and a range of unused archival sources, the book explores the overlapping contexts that enabled the growth of the movement and the diverse motivations that brought women into it but then led them to pursue quite different paths. As the movement developed, these interacted with political differences, strategic disagreements, and personality clashes to split the movement into separate strands, all sharing the same broad objectives but with different practical foci.This is the story of how a group of exceptional women, Emily Davies at their centre, challenged conventional ideas and created new opportunities for women. Situated in its broader social, cultural, and intellectual contexts, it will appeal to all those interested in Victorian social history, the history of feminism, and the history of education.
