The chapters in this volume provide a varied yet consistent analysis of the ways in which ideologies have been used, misused, or abandoned in Latin America in the twentieth century. The volume offers scholars and students a challenging collection of interpretations of and explanations for the ways in which ideologues and ideologies have played a crucial role in the political development of the continent. And, while illuminating key reasons for the rise and fall of specific ideologies and their repeated betrayal throughout the century-from anarchism to communism, to socialism, to Peronism, to neoliberalism-the volume indicates how much there is still left to learn about the importance of ideological discourse in the mind and polity of Latin America. With chapters examining Mexico, Chile, Cuba, Paraguay, and Argentina, this work will be of interest to all Latin Americanists.
