"Even in 1832 there were those in the South who confessed that the tariff was only a battlefield, not the war. If they did not fight their ground and win on the tariff, soon enough they would be fighting for something even closer to their hearths, slavery itself."

“Southern states had embraced the Union only insofar as it served to protect their rights to hold property in slaves, and to spread slavery as the nation expanded and the institution itself became intertwined as a defining element in the struggle for national power itself. In slavery could not spread as new states were formed, then the existing slave states would be doomed to perpetual minority in representation in Congress, guaranteeing that if the day came when Northern antipathy to slavery itself became hot enough, the majority could use the government to subvert the Constitution and abolish the institution where it already existed. In short, the South could not affort to lose any battle over slavery, nor even over issues on its periphery.”

“Legalistic Southerners tried to view the Constitution as a contract. Unfortunately, that viewpoint breaks down when viewed as a lawyer views a contract. There are very few ways to legally break a contract unilaterally.”

“The only substantial difference between them, and the one that divided them politically almost since birth, was their system of labor.”

“So long as the number of slave states was the same as or greater than the number of free states, then in the Senate the South had a check on the government.”

“Confederates were terrified of what was happening to slavery.”

“It is impossible to point to any other local issue but slavery and say that Southerners would have seceded and fought over it.”
