In a way that's true and in a way that's not true.
For most of the Union soldiers, at least at the outset, it was about preserving the Union.
For a lot of the Confederate soldiers it was a desire to protect their home area - a desire exploited by the movers and shakers of the CSA.
But for the slave owning soft hands that ran the CSA, it was ALL about slavery and their continuing to fatten their bank account by the sweat of their human "property". Anybody who doubts that need only read the words of the Confederates themselves in their secession justifications.
Same crap different day! But then if it was all about slavery, then why did the North invade the South when the Southern States invoked their 9th and 10th Amendment rights? You know, the Amendments that gave States the RIGHT of secession. But then I forget myself, you Yankees wrote your Constitution in pencil for easy facilitation of change when its expedient.
did you get that out of a LEFTIST book published at YALE or HARVARD or perhaps at BERKLEY????
