Written by leading historians of the mid-nineteenth century United States, this book focuses on the continental dimensions of the U.S. Civil War. It joins a growing body of scholarship that seeks to understand the place of America's mid-nineteenth-century crisis in the broader sweep of world history. However, unlike other studies that have pursued the Civil War's connections with Europe and the Caribbean, this volume focuses on North America, particularly Mexico, British Canada, and sovereign indigenous states in the West. As the United States went through its Civil War and Reconstruction, Mexico endured its own civil war and then waged a four-year campaign to expel a French-imposed monarch. Meanwhile, Britain's North American colonies were in complex and contested negotiations that culminated in confederation in 1867. In the West, indigenous nations faced an onslaught of settlers and soldiers seeking to conquer their lands for the United States. Yet despite this synchronicity, mainstream histories of the Civil War mostly ignore its connections to the political upheaval occurring elsewhere in North America. By reading North America into the history of the Civil War, this volume shows how battles over sovereignty in neighboring states became enmeshed with the fratricidal conflict in the United States. Its contributors explore these entangled histories in studies ranging from African Americans fleeing U.S. slavery by emigrating to Mexico to Confederate privateers finding allies in Halifax, Nova Scotia. This continental perspective highlights the uncertainty of the period when the fate of old nations and possibilities for new ones were truly up for grabs.

Most treatments of slavery, politics, and expansion in the early American republic focus narrowly on congressional debates and the inaction of elite "founding fathers" such as Thomas Jefferson and James Madison. In "Slavery, Freedom, and Expansion in the Early American West," John Craig Hammond looks beyond elite leadership and examines how the demands of western settlers, the potential of western disunion, and local, popular politics determined the fate of slavery and freedom in the West between 1790 and 1820.

By shifting focus away from high politics in Philadelphia and Washington, Hammond demonstrates that local political contests and geopolitical realities were more responsible for determining slavery's fate in the West than were the clashing proslavery and antislavery proclivities of Founding Fathers and politicians in the East. When efforts to prohibit slavery revived in 1819 with the Missouri Controversy it was not because of a sudden awakening to the problem on the part of northern Republicans, but because the threat of western secession no longer seemed credible.

Including detailed studies of popular political contests in Ohio, Indiana, Illinois, Mississippi, Louisiana, and Missouri that shed light on the western and popular character of conflicts over slavery, Hammond also provides a thorough analysis of the Missouri Controversy, revealing how the problem of slavery expansion shifted from a local and western problem to a sectional and national dilemma that would ultimately lead to disunion and civil war.
