Books describing political movements in the Antebellum South 

Hello.  I've been reading a biography of William H. Seward (Seward: Lincoln's Indispensable Man by Walter Star) and have gotten a basic idea of the political movements and players that shaped Northern policy and politics in the decades before the Civil War.  (Abolitionism, Nativism, Know Nothingism, Antimasonry, etc.)  I'm looking to expand my knowledge to better understand how the South's policies and politics evolved.  (I'm getting the impression that the South's politics were dominated by a relatively small landed aristocracy and might not have had such a proliferation of movements or diversity of politically influential thought, but I'm likely wrong and would like to learn about what did exist, at any rate.)  I noticed your comments on the talk page of one of Wikipedia's articles on the era and you seem to know a good deal about the topic.  Could you recommend a good book (or 3) that includes coverage of such topics?  Regards.
