Intersectionality theory in the context of "First-wave feminism"

Identity politics is politics based on a particular identity, such as ethnicity, race, nationality, religion, denomination, gender, sexual orientation, social background, political affiliation, caste, age, education, disability, opinion, intelligence, and social class. The term encompasses various often-populist political phenomena and rhetoric, such as governmental migration policies that regulate mobility and opportunity based on identities, left-wing agendas involving intersectional politics or class reductionism, and right-wing nationalist agendas of exclusion of national or ethnic "others".

The term identity politics dates to the late twentieth century, although it had precursors in the writings of individuals such as Mary Wollstonecraft and Frantz Fanon. Many contemporary advocates of identity politics take an intersectional perspective, which they argue accounts for a range of interacting systems of oppression that may affect a person's life and originate from their various identities. To these advocates, identity politics helps center the experiences of those they view as facing systemic oppression so that society can better understand the interplay of different forms of demographic-based oppression and ensure that no one group is disproportionately affected by political actions. Contemporary identity labels—such as people of specific race, ethnicity, sex, gender identity, sexual orientation, age—are not mutually exclusive but are, in many cases, compounded into one when describing hyper-specific groups. An example is that of African-American homosexual women, who can constitute a particular hyper-specific identity class.
