Answer:
1. The Southern states opposed emancipation and held large number of slaves.
Explanation: At the point when reunification was the sole objective of the North, the Confederates could be seen by outsiders as freedom contenders being held without wanting to by the Union.
But after the Emancipation Proclamation, the Southern cause was presently the defense of slavery. The declaration was a sagacious move by Lincoln to mark the Confederate States as a slave country and render foreign aid impossible.
