The Emancipation Proclamation shifted the aim of the Civil war to freeing of the slaves in addition to preserving the Union. This was the main accomplishment of the Proclamation - freeing of slaves. This led to prevention of European involvement in the war since many Europeans were against slavery. This was yet another of Lincoln's accomplishments being that Britain and France had considered supporting the Confederacy before The Proclamation. Although slavery was abolished only in rebellious states, by the end of the war, it had influenced and prepared citizens to accept the idea and even advocate the abolition of slavery. Also, with the Proclamation African Americans were received into the army of U.S.
Personally, I don't think so.
Every information we have is by principle, biased. We can never have a full picture on the issue (we don't live long enough to have ALL the information and all the other people's opinions) so this means that we only know a selection of relevant information. This selection biases our perception of the issue: so in this way, I think that we are bound to be at least a little bit biased.
