This book analyzes seven Latin American thinkers who have contributed to building bridges for reconciliation and peace: Carlos Saavedra Lamas, Adolfo Pérez Esquivel, Alfonso García Robles, Óscar Arias Sánchez, Rigoberta Menchú Tum, Juan Manuel Santos, and Javier Pérez de Cuéllar. Working within an eclectic conceptual approach to systematize the circulation of ideas embraced by each one of the thinkers, the various contributions delve into the current literature of leadership and intellectuals in Politics and Global International Relations (GIR). Overall, the central premises of the analysis are based on three fundamentals of mainstream constructivism: a) change across time and space in the lifetime of each thinker under analysis in this book; b) socialization through changing norms, rules, and language; and c) processes of interaction in which actors make choices in selecting networks and strategies). Coming from different walks of life, the seven thinkers examined in this book have accessed the global public square and discussed ideas to reduce conflicts at different scales. In their respective historical times, they circulated their views and ideas beyond the confines of Latin America to influence global political thought and produce change in favor of peace.
