As per:
The thing is though, economics, politics, it all came back to slavery.
During the war, Lincoln tried to persuade slaveowners in various US states/liberated territories (Delaware among them) to accept compensated emancipation; basically, this was one of the many policy options regarding reconstruction the Administration tried, in locations as diverse as US-controlled Louisiana and South Carolina to Tennessee and the border states.
Slaveowners were not interested - "not a federal issue" (seriously, that was the argument).

After all, as early as the 1830s, Calhoun et al were arguing that slavery was a "positive good"....
"...(slavery) has grown up with our society and institutions, and is so interwoven with them that to destroy it would be to destroy us as a people. But let me not be understood as admitting, even by implication, that the existing relations between the two races in the slaveholding States is an evil:–far otherwise; I hold it to be a good, as it has thus far proved itself to be to both, and will continue to prove so if not disturbed by the fell spirit of abolition. I appeal to facts. Never before has the black race of Central Africa, from the dawn of history to the present day, attained a condition so civilized and so improved, not only physically, but morally and intellectually."

No matter how hard various and sundry individuals have tried to obscure it since 1865, the South seceded over their various elites desire to
sustain and grow slavery, and the war occurred because the south seceded.
One can pretend otherwise, and the moonlight and magnolias/lost cause/some of my best friends are enslaved types will continue to do so for ever, but...
It's true.
Best,
