*There were exceptions for some Parasish in Lousinana and for now W Virginia.
There are two parts to the Emancipation Proclamation. In the first part, the slaves in the states in rebellion were freed (without compensation). In the second part, the slaves in the states loyal to the union were able to join the army with the enlistment bonus going to the owner as a form of compensation. The second part effectively ended slavery in the remainder of the country. Kentucky proceeded forthwith to emancipation through legislation, as did Maryland through a state constitutional amendment. In Delaware, there were only a few slaves, almost all of them elderly, and the legislature was concerned about the cost to the taxpayer of their emancipation when, under the slave system they were to be taken care of by their masters. I don’t know, off hand, what was going on in Missouri, or in the provisional (Yankee) state governments in Virginia or Louisiana. Regarding the 13th Amendment, there was never a debate about ending slavery through it, only about whether there should be compensation in the states loyal to the union. I loved Daniel Day Lewis’ Lincoln, but the movie was fake.
Secession wasn't rebellion. Lincoln merely proclaimed it to be "rebellion" because this unlocked vast powers for him to use, but in point of fact, the Southern states were not "Rebelling" by leaving the Union.
The Declaration of Independence gave them the right to do so, because it was this very same natural law principle upon which our own government was founded.
And for what it's worth, Chief Justice of the US Supreme Court, Salmon P Chase explicitly said that "Secession is not Rebellion."
In the effort to Try Jefferson Davis for Treason, Salmon P Chase also advised Federal prosecutors to drop the charges against Davis. He informed them that "they would lose everything in court that they had won on the battlefield."
Dude. President Lincoln was responsible for the passage of the 13th amendment through Congress. He signed the amendment upon passage. He was assassinated by agents of the South before it was enacted,
but President Lincoln clearly ended all Slavery in the US.
