An interdisciplinary field of research within the humanities and social sciences, disability studies originated in the United States and the United Kingdom in the late 1970s, in the wake of social movements of disabled people fighting against their exclusion from society. Since then, disability studies have become increasingly complex, to the point where they are now characterised by a plurality of currents, which this book presents in the order of their appearance, through the main concepts (disability pride, narrative prosthesis, normate, misfit, crip times, ableism, etc.) and models (social / affirmative / relational / cultural / African model of disability, etc.) that this field of research has forged to understand disability. Through the notions of disability, impairment and difference, this book focuses on the debates that have led to the diversification of disability studies and takes a position on the subject itself. It thus aims to contribute to raising awareness among the French-speaking public of disability studies and the politicisation of disability that they bring about.
