This article contends that the type of high-level political consensus needed to reach a peace agreement is often insufficient for rebuilding and transforming wider social relations. Consensus-focused processes tend to suppress divergent views and experiences of conflict, particularly among grassroots conflict actors, and risk deepening social divides by homogenising diverse memories of past violence, with potentially dangerous consequences. In response to these concerns this article advances an understanding of agonistic dialogue and explores an example of such dialogue in communal conflict in Indonesia. Building on an understanding of effective dialogue as sustained, intensive and relational, this article also underscores the need for effective dialogue to have politico-institutional support and to be locally driven and owned by actors who are legitimate and trusted in the eyes of conflict protagonists.
