The Subjection of Women is an essay by English philosopher, political economist and civil servant John Stuart Mill published in 1869, with ideas he developed jointly with his wife Harriet Taylor Mill. At the time of its publication, the essay's argument for equality between the sexes was an affront to European conventional norms regarding the status of men and women.
In his Autobiography, Mill describes his indebtedness to his wife, and his daughter Helen Taylor for the creation of The Subjection of Women:
As ultimately published it was enriched with some important ideas of my daughter's and some passages of her writing. But all that is most striking and profound in what was written by me belongs to my wife, coming from the fund of thought that had been made common to us both by our innumerable conversations and discussions on a topic that filled so large a place in our minds.
