The Oxford Handbook of Revolutionary Elections in the Americas, 1800-1910, presents a unique comparative political history spanning from Jefferson's election to the campaign that led to the Mexican revolution of 1910. By focusing on revolutionary elections-those of a contested, contentious nature that bore highly consequential outcomes-this volume sheds light on how institutions were inaugurated or transformed, how substantial issues were settled, and how political behaviour was changed. After offering overviews of the electoral history of the United States, Latin America and Canada, the Handbook examines key elections in Argentina, Brazil, Canada, Chile, Colombia, Costa Rica, Cuba, México, Perú, the US and Venezuela. Case studies of individual countries then serve as the basis for wider continental analysis of electoral violence, electoral corruption and electoral administration before concluding with some reflections on the need to approach the political history of the Americas from a comparative perspective. This wide lens makes this volume a novel contribution to the study of elections and an indispensable resource for anyone seeking to understand electoral politics and democracy in broader context.
