America's Great Debate: Henry Clay, Stephen A. Douglas, and the Compromise That Preserved the Union

Fergus M. Bordewich

The spellbinding story behind the longest debate in US Senate history: the Compromise of 1850, which brought together Senate luminaries on the eve of the Civil War in a desperate effort to save the Union. The Mexican War introduced vast new territories into the United States, among them California and the present-day Southwest. When gold was discovered in California in the great Gold Rush of 1849, the population swelled, and settlers petitioned for admission to the Union. But the U.S. Senate was precariously balanced with fifteen free states and fifteen slave states. Up to then states had been admitted in pairs, one free and one slave, to preserve that tenuous balance in the Senate. Would California be free or slave? So began a paralyzing crisis in American government, and the longest debate in Senate history. Fergus Bordewich tells the epic story of the Compromise of 1850 with skill and vigor, bringing to life two generations of senators who dominated the great debate. Luminaries such as John Calhoun, Daniel Webster, and Henry Clay—who tried unsuccessfully to cobble together a compromise that would allow for California’s admission and simultaneously put an end to the nation’s agony over slavery—were nearing the end of their long careers.
