This chapter argues that a comprehensive understanding of disability is impossible without an intersectional analysis that centers the experiences of marginalized communities. Disability does not exist in a vacuum; it is profoundly shaped by other social categories such as race, class, gender, sexual orientation, and migration status. The chapter begins by establishing the theoretical framework of intersectionality, tracing its roots in Black feminist thought and explicating its critical application to disability studies. Through detailed case studies, it demonstrates how interlocking systems of oppression including racism, sexism, ableism, and economic injustice produce unique and compounded forms of disablement. The analysis then scrutinizes the systemic barriers embedded within judicial, healthcare, and social service institutions that disproportionately harm marginalized disabled people. In response, the chapter advocates for an inclusive praxis that prioritizes community-based participatory research, culturally responsive support, and solidarity across movements. It concludes with a forward-looking discussion on the necessity of decolonizing disability studies, incorporating global and Indigenous perspectives, and reorienting policy and advocacy toward intersectional justice. The central thesis is that the transformation of disability studies hinges on its ability to confront and dismantle all intersecting forms of structural inequality.
