John C. Calhoun developed his concept of nullification in response to Yankee-inspired protective tariffs over 3 decades before the Civil War, proving that tariffs were a long-running bitter issue between North & South. The only difference between the Confederate constitution and the U.S. one was that the Confederate one banned protective tariffs. Try reading some real history for a change, instead of Unionist propaganda.
Surely not the only difference.
What about additional guarantees to slaveowners?
And yet nobody seceded because no other state supported South Carolina's position and Andrew Jackson made it clear that he believed secession was illegal and he would oppose it militarily if necessary.

I have. For example I've read enough to know that one of the first actions of the confederate congress was the implementation of a tariff that had protectionist features in it. And odd act if tariffs were really the major bone of contention you claim it was.
