In feminist theory, heteropatriarchy (etymologically from heterosexual and patriarchy) or cisheteropatriarchy, is a social construct where (primarily) cisgender (same gender as identified at birth) and heterosexual males have authority over other cisgender males, females, and people with other sexual orientations and gender identities. It is a term that emphasizes that discrimination against women and LGBT people is derived from the same sexist social principle.[1][2][3]
The concept postulates that in heteropatriarchal societies, cisgender heterosexual men generally occupy the highest positions of power in society, causing women (including transgender women), non-binary people, transgender men, and other LGBT people to experience the bulk of social oppression in relation to gender and sexuality.[1]
