Origins of the American Civil War [SEP] Introduction
Historians debating the origins of the American Civil War focus on the reasons why seven Southern states (followed by four more after the onset of the war) declared their secession from the United States (the Union), why they united to form the Confederate States of America (simply known as the "Confederacy"), and why the North refused to let them go. While virtually all historians in the 21st century agree that conflicts over slavery caused the war, they disagree sharply regarding which kinds of conflict—ideological, economic, political, or social—were most important. The primary catalyst for secession was slavery, most immediately the political battle over the right of Southerners to bring slavery into western territory that had hitherto been free under the terms of the Missouri Compromise or while part of Mexico.
