Examines the evolving lives of two men who were crucial political figures in the consequential decades prior to the Civil War Although neither of them lived to see the Civil War, John Quincy Adams and John C. Calhoun did as much any two political figures of the era to shape the intersectional tensions that produced the conflict. William F. Hartford examines the lives of Adams and Calhoun as a prism through which to view the developing sectional conflict. While both men came of age as strong nationalists, their views, like those of the nation, diverged by the 1830s, largely over the issue of slavery. Hartford examines the two men's responses to issues of nationalism and empire, sectionalism and nullification, slavery and antislavery, party and politics, and also the expansion of slavery. He offers fresh insights into the sectional conflict that also accounts for the role of personal idiosyncrasy and interpersonal relationships in the coming of the Civil War.
