Intersectionality is a key concept in contemporary feminist discourse, examining the disproportionate impact of oppression on individuals due to interlocking identity factors like race, gender, class, sexuality, disability, or nationality. Originating in the late 1980s, it has evolved over decades of thought and struggle by black and indigenous feminists and other women of color. This article provides an overview of intersectionality, its definition, historical origins, main theorists, and application in contemporary society. It also examines the debates surrounding the concept and its ongoing contribution to women’s studies. The paper is divided into four chapters, focusing on conceptual analysis, origins, activism, policy frameworks, and a critical perspective.
