The study of masculinity, particularly in peacebuilding and transitional justice contexts, is gradually emerging. The article outlines three fissures evident in the embryonic scholarship, that is the privileging of direct violence and its limited focus, the continuities and discontinuities in militarised violence into peace time, and the tensions between new masculinities and wider inclusive social change. The article argues for the importance of making visible the tensions between different masculinities and how masculinities are deeply entangled with systems of power and (...) post-conflict social, political and economic outcomes. An analysis of masculine power within and between the structures aimed at building the peace in societies moving out of violence is considered essential. The article argues for an analysis that moves beyond a preoccupation with preventing violent masculinities from manifesting through the actions of individuals to considering how hidden masculine cultures operate within a variety of hierarchies and social spaces.
