In 1932 Bolivia and Paraguay went to war over the Chaco region in South America. The war lasted three years and approximately 52,000 Bolivians and Paraguayans died. Moving beyond the battlefields of the Chaco War, this volume highlights the forgotten narratives of the war. Studying the environmental, ethnic, and social realities of the war in both Bolivia and Paraguay, the contributors examine the conflict that took place between 1932 and 1936 and explore its relationship with and impact on nationalism, activism and modernity. Beginning with an overview of the war, the book goes on to explore many new approaches to the conflict, and the contributors address topics such as the environmental challenges faced by the forces involved, the role of indigenous peoples, the impact of oil nationalism and the conflict's aftermath. This is a volume that will be of interest to anyone working on modern Latin America and the relationship between war and society. The Chaco War is a well-rounded contribution that will be of interest to scholars of Latin American history, political science, culture, and literature. Bolivian and Paraguayan specialists will find it especially fascinating, but it will be useful to students of modern Latin America, nationalism, warfare, frontiers, and indigenous history as well.
