In the latter half of the nineteenth century, three violent national conflicts rocked the Americas: the Wars of Unification in Argentina, the War of the Reform and French Intervention in Mexico, and the Civil War in the United States. The recovery efforts that followed reshaped the Western Hemisphere. In Civil Wars and Reconstructions in the Americas, Evan C. Rothera uses both transnational and comparative methodologies to highlight similarities and differences among the wars and reconstructions in the US, Mexico, and Argentina. In doing so, he uncovers a new history that stresses the degree to which cooperation and collaboration, rather than antagonism and discord, characterized the relationships among the three countries. This study serves as a unique assessment of a crucial period in the history of the Americas and speaks to the perpetual battle between visions of international partnership and isolation.
