 Instersectionality, which is in part a theory of power, grew out of groundbreaking works by Black feminist theorists such as Kimberlé Crenshaw’s “Demarginalizing the Intersection of Race and Sex: A Black Feminist Critique of Antidiscrimination Doctrine, Feminist Theory and Antiracist Practice” (Crenshaw 1989), Patricia Hill Collins’s book Black Feminist Thought: Knowledge, Consciousness and the Politics of Empowerment (Collins 1990), Angela Davis’s Women, Race, and Class (Davis 1981), and Patricia Williams’s The Alchemy of Race and Rights (Williams 1992). The impact of this work was felt strongly where it originated in feminist legal theory (see  feminist philosophy of law), and has continued to be an important concept for theories of power and oppression in and out of feminist political philosophy.
