Overview
Queer theory is derived largely from post-structuralist theory, and deconstruction in particular. Starting in the 1970s, a range of authors brought deconstructionist critical approaches to bear on issues of sexual identity, and especially on the construction of a normative "straight" ideology. Queer theorists challenged the validity and consistency of heteronormative discourse, and focused to a large degree on non-heteronormative sexualities and sexual practices.
The term "queer theory" was introduced in 1990, with Eve Kosofsky Sedgwick, Judith Butler, Adrienne Rich and Diana Fuss (all largely following the work of Michel Foucault) being among its foundational proponents.
