They resisted the progressive (at the time) end of human enslavement/forced labour on just the basis of skin colour.

That wasn't the reason for the war according to Lincoln, the corporate railroad attorney turned President. He is the only president to call for an amendment to make slavery express and irrevocable:

I understand a proposed amendment to the Constitution, which amendment, however, I have not seen, has passed Congress, to the effect that the federal government shall never interfere with the domestic institutions of the States, including that of persons held to service. To avoid misconstruction of what I have said, I depart from my purpose not to speak of particular amendments, so far as to say that holding such a provision to now be implied constitutional law, I have no objection to its being made express and irrevocable.

He also explicitly stated that he would only invade the south if they didn't pay their taxes:

In doing this there needs to be no bloodshed or violence; and there shall be none, unless it be forced upon the national authority. The power confided to me will be used to hold, occupy, and possess the property and places belonging to the government, and to collect the duties and imposts; but beyond what may be necessary for these objects, there will be no invasion -- no using of force against or among the people anywhere.

The civil war started because the Northern robber-barons wanted to tax the South to subsidize their corporate railroads.
