I stand corrected. I do think it should be noted that only 16 blacks qualified to vote under those requirements, which were more stringent than those for white men. Still, a notable acheivement at the time.

And yes, I would like references to more. The vast majority of histories of blacks in America do not cover local laws at all.

But I still maintain that slavery was not the sole cause of the war. The abolitionists were a vocal minority in the North. That does not mean that that was the cause of the war. I am certain that 100 years from now, so many children will have have educations that completely ignore the taxation issues, tariffs waged against the southern states to protect northern industry, and other complex issues that increased the tension between the regions that had been growing from 1787 onward. The South was a cash cow for the north, and they resented it.
