Employing previously unused sources and reexamining existing ones, MacKenzie argues that West Virginia experienced the Civil War in the same ways as the border states of Missouri, Kentucky, Maryland, and Delaware. Like these northernmost slave states, northwestern Virginia supported the institution of slavery out of proportion to the actual presence of enslavement there. The people who became West Virginians built a new state first to protect slavery, but radical Unionists and escaping slaves forced emancipation on the statehood movement. MacKenzie shows how conservatives and radicals clashed over Black freedom, correcting many myths about West Virginia’s origins and making an important addition to the literature in Appalachian and Civil War history.
