This chapter examines the intersection of formal and informal peace infrastructures in Madagascar, highlighting how indigenous mechanisms contribute to conflict resolution and social cohesion. Moving beyond the limitations of externally imposed peacebuilding models, it explores how cultural values—such as Fihavanana, Tsiny, and Tody—shape both community-led and institutional approaches to peace. It studies the extent to which grassroots peace infrastructures, including Fokonolona assemblies and Tragnô Be sacred spaces are essential for fostering local legitimacy and are operating within broader national and international frameworks. Additionally, it examines the evolving role of the army, the church, and national reconciliation councils in stabilizing or disrupting peace efforts. By integrating historical analysis with contemporary examples, the chapter argues that sustainable peace in Madagascar depends on transcalar dynamics—one that balances state authority with community agency and ensures that reconciliation efforts are both participatory and contextually relevant.
