The second and concluding volume of Professor Ashworth's study of American antebellum politics, this book offers an exciting new interpretation of the origins of the Civil War. The volume deals with the politics of the 1850s and with the plunge into civil war. Professor Ashworth offers a new way of understanding the conflict between North and South and shows how northern free labor increasingly came into conflict with southern slavery as a result of both changes in the northern economy and the structural weaknesses of slavery.
