Slavery and the American West: The Eclipse of Manifest Destiny and the Coming of the Civil War
Days of Defiance: Sumter, Secession, and the Coming of the Civil War
The Confederate War
Two issues that have generated the most animated debates among historians of the American Civil War are the causes of the war and the causes of Confederate defeat. Indeed, these are among the most important questions in all of American history. If the war had never happened, or if it had occurred but the Confederacy had won its independence, the United States would be an incalculably different country today. As Mark Twain put it a few years after Appomattox, the war “uprooted institutions that were centuries old, changed the politics of a people, transformed the social life of half the country, and wrought so profoundly upon the entire national character that the influence cannot be measured short of two or three generations.” Five generations later, historians are still trying to measure its influence and explain its origins and outcome.

The existence of African servitude was in no wise the cause of the conflict, but only an incident.”
When Davis and Stephens wrote these apologias, slavery was a dead and discredited institution. To concede that the Confederacy had broken up the United States and launched a war that …
