The issue of a female right to vote first gathered momentum during the latter half of the nineteenth century. In 1865, the Kensington Society, a discussion group for middle-class women who were barred from higher education, met at the home of Indian scholar Charlotte Manning in Kensington. Following a discussion on suffrage, a small informal committee was formed to draft a petition and gather signatures, led by women including Barbara Bodichon, Emily Davies, and Elizabeth Garrett. In 1869, John Stuart Mill, published "The Subjection of Women" (1861, published 1869), one of the earliest works on this subject by a male author. In the book, Mill attempts to make a case for perfect equality. He talks about the role of women in marriage and how it needed to be changed, and comments on three major facets of women's lives that he felt were hindering them: society and gender construction, education, and marriage. He argued that the oppression of women was one of the few remaining relics from ancient times, a set of prejudices that severely impeded the progress of humanity. He agreed to present a petition to Parliament, provided it had at least 100 signatures, and the first version was drafted by his step-daughter, Helen Taylor.
