Answer:

Slavery played a central role during the American Civil War. The primary catalyst for secession was slavery, especially Southern political leaders' resistance to attempts by Northern antislavery political forces to block the expansion of slavery into the western territories. Slave life went through great changes, as the South saw Union Armies take control of broad areas of land.During and before the war, slaves played an active role in their own emancipation, and thousands of slaves escaped. The institution of race-based slavery defused class tensions among whites because no matter how poor they were, white southerners had raced in common with the mighty plantation owners. Significantly, all white southerners were also bound together by the constant, prevailing fear of slave uprisings.
