Professor Blight begins this lecture with an attempt to answer the question "why did the South secede in 1861?" Blight offers five possible answers to this question: preservation of slavery, "the fear thesis," southern nationalism, the "agrarian thesis," and the "honor thesis." After laying out the roots of secession, Blight focuses on the historical profession, suggesting some of the ways in which historians have attempted to explain the coming of the Civil War. Blight begins with James Ford Rhodes, a highly influential amateur historian in the late nineteenth century, and then introduces Charles and Mary Beard, whose economic interpretations of the Civil War had their heyday in the 1920s and 1930s.
