Not quite the Cotton Kingdom or the free labor North, the mid-nineteenth-century border South was a land in between. There, the clashing ideologies of this era—slavery and freedom, urban and rural, industrial and agrarian—met, merged, and melded. As they did, they formed something new—a fluid, flexible identity that somehow grew from these tensions while rising above them. This border identity would play a critical role in these states’ experiences during the secession crisis, the Civil War, and Reconstruction. Yet, this story—one of political division, internal warfare, and economic struggles—is only one part of the border South’s larger saga. Focusing on the heart of this complicated region, Marriage on the Border reveals how this border environment shaped the lives and loves of Kentuckians, West Virginians, and Appalachian Virginians. Inundated with conflicting messages about marriage, divorce, and gender, these border southerners set their own path. In an era when advice manuals urged all Americans to adopt new ideals of companionate marriage and loving mutuality, border southerners proved especially receptive to these notions. Additionally, when these marriages crumbled, border southerners found ways to divorce more easily than other southerners of this era. Marriage on the Border follows border southerners through their courtships and into their homes, through blissful marriages and turbulent divorce dramas, through secession, war, and reconstruction. Along the way, Marriage on the Border captures the turmoil and confusion of this era, not in its legislative halls or on the battlefield, but in the households of those who lived at the heart of the country.
