In this groundbreaking biography, author Patrick A. Lewis uses Buckner's story to illuminate the origins and perspectives of Kentucky's conservative proslavery Unionists and explain why this group became a key force in repressing social and political change during the Reconstruction era and beyond. While other studies have explored how this former Union state cultivated a Confederate identity after the Civil War, For Slavery and Union is the first major work to personify this transformation. Lewis's book provides a deeply nuanced look at the history of the Commonwealth in the nineteenth century and the development of the New South.
