Judith Sargent Murray was an American writer who wrote the poem and essay "On the Equality of the Sexes" under the pseudonym Constantia in 1790. In the work, Murray questions the subservience of women to men and argues that the lack of education for women leads to inequality in reason and judgment between the sexes. The themes of the work include women's issues, gender roles, and the inequality created by denying women access to education and literature.
