Identity politics is politics based on a particular identity, such as race, nationality, religion, gender, sexual orientation, social background, social class. Depending on which definition of identity politics is assumed, the term could also encompass other social phenomena which are not commonly understood as exemplifying identity politics, such as governmental migration policy that regulates mobility based on identities, or far-right nationalist agendas of exclusion of national or ethnic others. For this reason, Kurzwelly, Pérez and Spiegel, who discuss several possible definitions of the term, argue that it is an analytically imprecise concept.
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 accounts for the range of interacting systems of oppression that may affect their lives and come from their various identities. According to many who describe themselves as advocates of identity politics, it centers the lived experiences of those facing systemic oppression; the purpose is to better understand the interplay of racial, economic, sex-based, and gender-based oppression (among others) and to ensure no one group is disproportionately affected by political actions, present and future. Such contemporary applications of identity politics describe people of specific race, ethnicity, sex, gender identity, sexual orientation, age, economic class, disability status, education, religion, language, profession, political party, veteran status, recovery status, and geographic location. These identity labels 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 constitute a particular hyper-specific identity class.
