Freedom during the Civil War

As you remember my topic is freedom, which I'll be applying to the civil war period. The obvious thing to right about is emancipation, which started with the emancipation proclamation  I read this link.  Although the proclamation took effect on January 1st 1863, Lincoln had released it several months prior following the union victory at Antietam. It originally applied to parts of the confederacy, but introduced abolition to northern war aims for the first time. Eventually all slaves were freed in 1865 by the 13th amendment.
