You are the one who seems to be illiterate of history here. Lincoln was an abolitionist and his plan for abolition was to gradually get rid of slavery over time. (Gradual Abolition) His solution for dealing with the uncomfortable consequences of free slaves running loose in white society was to ship them off to Central America or back to Africa.
Lincoln always said he was NOT an abolitionist. He opposed slavery but said he had neither the authority nor inclination to do anything about it. Eventually he issued the EP but that didn't free any slaves.
You actually had a post that had something correct- all the way up to the Emancipation Proclamation- when you spewed the revisionists BS line.
All of the slaves in the territories marked in red were immediately freed by the Emancipation Proclamation- an estimated 20,000 slaves.
All of the areas is pink (or taupe) were the areas that eventually had all of the slaves freed by the Emancipation Proclamation. The Emancipation Proclamation freed the majority of slaves in America.
You will note, all the "freed slaves" are in the CSA. Lincoln had no authority in the CSA.
What Lincoln did was actually a very questionable Constitutional act. As CinC of the military, he is authorized to seize enemy property in the name of "spoils of war" or as military strategy. This is why it could not pertain to the 400k slaves in the blue areas of your map.
If you contend the CSA was never a country in it's own right, and the Confederacy was simply a rebellion of US citizens, then the Emancipation Proclamation is unconstitutional.
Slaves in the United States were not free until ratification of the 13th, 14th and 15th Amendments.
