The Subjection of Women is the title of an essay written by John Stuart Mill in 1869, possibly jointly with his wife Harriet Taylor Mill, stating an argument in favour of equality between the sexes. At the time it was published in 1869, this essay was an affront to European conventional norms for the status of men and women. Mill was convinced that the moral and intellectual advancement of humankind would result in greater happiness for everybody. He argues that people should be able to vote to defend their own rights and to learn to stand on their two feet, morally and intellectually. This argument is applied to both men and women. Mill often used his position as a member of Parliament to demand the vote for women, a controversial position for the time.
