I should add that the North had been punishing the South for decades with tariffs that favored the manufacturers over the growers.
Winner!
Total rubbish, an absolute lie...
First of all, tariffs were only on imports, and since there were no imports of Southern agricultural products (i.e., cotton, tobacco), there was nothing for Federal government to protect against.
And in fact, those import tariffs in 1860 were as low as ever -- less than half of the "Tariff of Abominations" (35%) passed by Tennessean Andrew Jackson's supporters and South Carolinian Vice President Calhoun in 1828, reduced only slightly by President Jackson in 1832.
Point is: tariffs were standard "politics as usual" in our young republic, they went up, they went down, and in 1860 were the same rate (15%) as in 1792 under Founding President George Washington.
So tariffs were in no-way, shape or form the cause of Deep South declarations of secession.
The real cause was slavery, as secessionists officially explained, for example, here.
