After several decades saturated in this narrative, in 1975 Norwegian sociologist Johan Galtung coined the term "peacebuilding" in his pioneering work "Three Approaches to Peace: Peacekeeping, Peacemaking, and Peacebuilding." In this article, he posited that "peace has a structure different from, perhaps over and above, peacekeeping and ad hoc peacemaking... The mechanisms that peace is based on should be built into the structure and be present as a reservoir for the system itself to draw up. ... More specifically, structures must be found that remove causes of wars and offer alternatives to war in situations where wars might occur." Galtung's work emphasized a bottom-up approach that decentralized social and economic structures, amounting to a call for a societal shift from structures of coercion and violence to a culture of peace. He catalyzed a major shift in the post-WWII global narrative by emphasizing how political, economic, & social systems need to address the root causes of conflict and support local capacity for peace management and conflict resolution.
