The History of Sexuality (French: L'Histoire de la sexualité) is a four-volume study of sexuality in the Western world by the French historian and philosopher Michel Foucault, in which the author examines the emergence of "sexuality" as a discursive object and separate sphere of life and argues that the notion that every individual has a sexuality is a relatively recent development in Western societies.
