It still generated 3 million dollars before the war ended. I guess from border states? Not sure.
Not sure either, large areas of TN,&VA and lower LA were occupied by Union forces early in the war, maybe cotton production in these areas produced that much tax money. The states of MO,KY and MD did not produce that much cotton.
I think these trolls that are on this thread are high school kids. They don’t sound like adults to me. They have very little knowledge about history or the reason for the cotton tariffs. Its probably just a hobby for them. Kids will be kids. :-)
