Slavery and the American West: The Eclipse of Manifest Destiny

Description

Tracing the sectionalization of American politics in the 1840s and 1850s, Michael Morrison offers a comprehensive study of how slavery and territorial expansion intersected as causes of the Civil War. Specifically, he argues that the common heritage of the American Revolution bound Americans together until disputes over the extension of slavery into the territories led northerners and southerners to increasingly divergent understandings of the Revolution's legacy. Manifest Destiny promised the literal enlargement of freedom through the extension of American institutions all the way to the Pacific. At each step—from John Tyler's attempt to annex Texas in 1844, to the Kansas-Nebraska Act, to the opening shots of the Civil War—fthe issue of slavery had to be confronted. Morrison shows that the Revolution was the common prism through which northerners and southerners viewed these events and that the factor that ultimately made consensus impossible was slavery itself. By 1861, no nationally accepted solution to the dilemma of slavery in the territories had emerged, no political party existed as a national entity, and politicians from both North and South had come to believe that those on the other side had subverted the American political tradition.
