Introduction

Summary

The Civil War in the lower Mississippi valley demonstrates the complexities of abolishing slavery. Focusing mostly on the Emancipation Proclamation, historians fail to explain how military emancipation was translated into abolition, viewing the Thirteenth Amendment as a stand-alone measure that gave constitutional sanction to the proclamation and that followed inevitably from it. However, abolition must be understood in conjunction with restoring the seceded states to the Union, since Americans generally believed that only states could abolish slavery. After the proclamation, Unionists in Louisiana and Tennessee split into free-state and proslavery – or “conservative” – factions, with both attempting to organize loyal governments. Taking proslavery Unionism seriously, Republicans insisted that the rebellious states abolish slavery in their state constitutions as a condition for readmission. The Thirteenth Amendment was thus originally envisioned to complement state action. Federal military success in the lower Mississippi valley first elucidated the problem of conjoining abolition and state restoration, and the region served as the crucible for transforming military emancipation into constitutional abolition.
