Intersectionality examines how social identities like race, gender, and class intersect to create unique experiences of privilege and oppression. This concept, coined by Kimberlé Crenshaw in 1989, addresses the limitations of single-axis frameworks and recognizes that individuals can belong to multiple marginalized groups simultaneously. Rooted in Black feminist thought, intersectionality has expanded to include various social identities and inform contemporary social justice movements. It challenges the notion of universal experiences within groups, emphasizing the need for nuanced approaches in research, policy, and activism to address complex social inequalities.
