I strongly disagree with the “not about slavery” comments. Since the writing of the constitution the south was worried about slaves having full rights. Look at how they were only counted as a fraction from the beginning.
The south wailed and gnashed their teeth as new states were created to make sure slave and fee states were equal in number.
From the time of his election to the inauguration, 7 states seceded because Lincoln opposed slavery and was likely to support more free states coming in.
So you can piss and moan about states rights, but it was keeping people as property the state was interested financially and otherwise. That was the right they wanted to maintain.
“Since the writing of the constitution the south was worried about slaves having full rights. Look at how they were only counted as a fraction from the beginning.”
Actually, the South WANTED slaves to be fully counted because by doing so this would give the South more representatives in the House.
The number of House representatives is based on the population of a state, and the South had many slaves and wanted the slaves to be counted as full persons so they would then be added to the total population count and generate more House representatives, thereby giving the slave-holding states more power.
The North wanted to limit the influence of the southern slave-holding states and not count fully the slave population, hence the 3/5th compromise.
