The Emancipation Proclamation did not immediately free slaves, as the rebel states would obviously not follow the orders given by Lincoln.
Here are the true statements: -It most definitely changed the significance of the war, for after a long war, people were starting to question what they were even fighting for.
-It did not free slaves in southern held territory.
-It arguably did end the threat of English recognition of the Confederacy, and for an interesting reason. Beforehand, England had no issue with providing aid to the Confederacy. However, once Lincoln made the war also focused on slavery, it would not have looked good for England to openly support the Confederacy any more.
