The south paid no tariffs, tariffs are paid by foreign exporters. The south controlled the tariff issue in the 1850s.
Nope not tariffs, it was slavery, as their Declarations of Secession make clear.
You just do not understand how the finances of that time period worked. 75% of everything exported was Southern Agriculture products. The import equation must balance, and it cannot balance unless you acknowledge that the biggest chunk of that import money/goods/services was paid for by those exports.
The record keeping is irrelevant, the place where the tariff's were collected is irrelevant, the only thing that matters is that Southern Products were most of what was being sold to Europe, and therefore most of the money earned from Europe was the consequence of those same products.
I was not discussing the reason for succession - I was discussing the reason for the war. THAT falls on the greed of the North.
Sorry!
