Heteropatriarchy

Heteropatriarchy (etymologically from hetero[sexuality] and patriarchy) is a socio-political system in which the male gender and the heterosexuality have primacy over other genders and over other sexual orientations.

From the feminist vision, the term patriarchy refers to the father as the power holder inside the familiar hierarchy, and therefore, to the subordination of women to the power of men. With the emergence of queer theory around the 1980s and the 1990s and the questioning of the heteronormativity and the gender binarism, this kind of domination is not only described in terms of sex or gender (the predominance of men over woman, or the masculine over the feminine) but also in terms of sexuality (the heteronormativity, or the heterosexuality above other sexual orientations and the cisgender over other identities).
