Peace is not simply the absence of violence, oppression, and marginalisation. Building peaceful spaces requires an integrative, culturally affirming response. Such a proactive approach is particularly pressing when designing welcoming and trauma-healing institutional support systems for new immigrants and refugees. Our transdisciplinary, trans-Atlantic approach to the praxis of peace combines an analysis of Galtung’s (1990) personal, structural, and cultural forms of violence, along with Cobb’s narrative violence (2013) with Yosso’s (2005) theory of community cultural wealth. Highlighting examples from Germany, the United Kingdom, and the United States, we critique how multi-layered, asset-based theories can counter the pernicious deficit-based frames underlying neoliberal constructs and conventions. Focusing on institutional, individual, community, and caregiver levels, we offer on-the-ground accounts of the work of universities, non-governmental agencies, and educators who can widen our repertoire of effective strategies for mobilising the shared strengths necessary for collective peacebuilding.
