Book excerpt: Starting in 1837, rebels in Upper and Lower Canada revolted against British rule in an attempt to reform a colonial government that they believed was unjust. While this uprising is often perceived as a small-scale, localized event, Revolutions across Borders demonstrates that the Canadian Rebellion of 1837–38 was a major continental crisis with dramatic transnational consequences. In this groundbreaking study, contributors analyze the extent of the Canadian Rebellion beyond British North America and the turbulent Jacksonian period's influence on rebel leaders and the course of the rebellion. Exploring the rebellion's social and economic dimensions, its impact on American politics, policy-making, and the philosophy of manifest destiny, and the significant changes south of the border that influenced this Canadian uprising, the essays in this volume show just how malleable borderland relations were. Chapters investigate how Americans frustrated with the young republic considered an “alternative republic” in Canada, the new monetary system that the rebels planned to establish, how the rebellion played a major role in Martin Van Buren's defeat in the 1840 presidential election, and how America's changing economic alliances doomed the Canadian Rebellion before it even started. Reevaluating the implications of this transnational conflict, Revolutions across Borders brings new life and understanding to this turning point in the history of North America.
