Im not reading this thread but im posting what i know.
The war was fought over the rights of the southern states vs the government. Lincoln made it about slavery when the south was lobbying for englands help because England needed the souths products. Lincoln knew if he made the war about slavery, then England would technically be fighting for slavery which would keep them out of it which is exactly what happened. The fact of the matter was that barely anyone in the south owned slaves because they couldnt afford it. It is also a popular idea that Lincoln abolished slavery which was also wrong. The Emancipation Proclomation freed slaves in states controlled by the Union. The South was its own entity and didnt listen to the laws of the Union for that time so the EP didnt apply to them. As the Union started taking states back throughout the war, the slaves were freed in those states but the over-all consensus that Lincoln freed the slaves is wrong because he did not. The Amendment ( cant remember which number) freed all slaves.
