LOL!! Virtually all you say? Last time I checked there were 11 states, but hmmm..only 4 formal declarations of secession. That's not even a majority son. As for reason perhaps we should look to the address of the people of South Carolina in Dec 1860.
And so with the Southern States, towards the Northern States, in the vital matter of taxation. They are in a minority in Congress. Their representation in Congress is useless to protect them against unjust taxation; and they are taxed by the people of the North for their benefit, exactly as the people of Great Britain taxed our ancestors in the British Parliament for their benefit. For the last forty years, the taxes laid by the Congress of the United States, have been laid with a view of subserving the interests of the North. The people of the South have been taxed by duties on imports, not for revenue, but for an object inconsistent with revenue - to promote, by prohibitions, Northern interests in the productions of their mines and manufactures.
There is another evil, in the condition of the Southern towards the Northern States, which our ancestors refused to bear towards Great Britain. Our ancestors not only taxed themselves, but all the taxes collected from them, were expended amongst them. Had they submitted to the pretensions of the British Government, the taxes collected from them would have been expended in other parts of the British Empire. They were fully aware of the effect of such a policy in impoverishing the people from whom taxes are collected, and in enriching those who receive the benefit of their expenditure. To prevent the evils of such a policy was one of the motives which drove them on to revolution. Yet this British policy has been fully realized towards the Southern States by the Northern States. The people of the Southern States are not only taxed for the benefit of the Northern States, but after the taxes are collected, three- fourths of them are expended at the North. This cause, with others, connected with the operation of the General Government, has made the cities of the South provincial. Their growth is paralyzed; they are mere suburbs of Northern cities. The agricultural productions of the South are the basis of the foreign commerce of the United States; yet Southern cities do not carry it on. Our foreign trade is almost annihilated. In 1740, there were five ship-yards in South Carolina, to build ships to carry on our direct trade with Europe. Between 1740 and 1779, there were built in these yards, twenty-five square rigged vessels, besides a great number of sloops and schooners, to carry on our coast and West India trade. In the half century immediately preceding the Revolution, from 1725 to 1775, the population of South Carolina increased seven-fold.

What is mentioned first and foremost in this address? Interestingly enough, taxes, the most heinous matter forced upon the South by the north
