Summary

The concept of post-hegemonic regionalism describes the scenario that has characterized Latin American regionalism in the last two decades. It first builds from Amitav Acharya’s work, in which he envisaged the end of United States hegemony and a world order of multiple leadership and power competitions, a scenario that he calls a “multiplex world.” To a large extent, post-hegemonic regionalism grew at odds with U.S. regional and hemispheric ambitions of market-led governance and in a context of weakened U.S. hegemony in Latin America. As a concept, denotes the region as a political space in which transborder governance is anchored in a new consensus about what cooperation and diplomacy is and is for, giving way to a reorganization of the regional scenario and the emergence of diverse efforts in new areas of cooperation. With this in mind, post-hegemonic regionalism is both a theory-based concept, contributing to a debate and a research agenda that branched out in the study of southern regionalism, as much as a manifestation of governance that re-signified and valued the regional space as one of action and contestation.
