Bernd Rother's book is a fundamental contribution to the study of contemporary political history. It reconstructs and explains in detail a series of political processes that have not been studied much, despite being the basis of the third wave of democratization in the 1980s and 1990s. Following Willy Brandt's transnational activity, Global Social Democracy offers an approach where the ideas and strategies of political actors take on great importance, revealing a world where politics—and especially social democracy—was no longer confined within national or regional borders. This book is the product of an exhaustive review of sources and interviews that makes it essential reading for specialists and those interested in the history of the twentieth century, but also for locating the roots, agendas, and even the protagonists of the current situation in Latin America.
