The inclusion of people with disabilities can facilitate sustainable peace after civil war. To shed a novel light on the relationship between war-to-peace transitions and disability, we map approaches to impairments in 286 worldwide intra-state political agreements, before considering the experience of Lebanon. Through a rigorous mixed methods research design, we show that war-to-peace transitions entrench the marginalisation of people with disabilities. Political agreements reproduce oversimplified understandings of disability; emphasise war-related physical impairments over non-physical and congenital ones; and prioritise support for former combatants. In Lebanon, disability-related legislation suffers from similar blind spots and remains unimplemented because of lack of financial resources, of weak capacity and cooperation among responsible local and international agencies, and of the features of the local political settlement. We discuss some significant implications for the lives of people with disabilities and their families, before providing recommendations to promote inclusive war-to-peace transitions. POINTS OF INTEREST Peace processes provide a crucial window of opportunity to build more inclusive societies. At a global level, civil war peace agreements overlook people with disabilities. Even when they mention impairments, peace accords adopt oversimplified understandings of disability, prioritise war-related physical impairments over non-physical and congenital ones, and emphasise interventions in support of former combatants. In Lebanon, lack of financial resources, weak capacity and cooperation among responsible local and international agencies, and local political dynamics further constrain the implementation of disability-focused policies. Globally, discourses on transition between civil war and a peaceful and just future, remain ableist and disempowering.
