When was emancipation proclamation signed, and howv did it shape the civil war?

Abraham Lincoln issued the preliminary Emancipation Proclamation on September 22nd, 1862. It stipulated that if the Southern states did not cease their rebellion by January 1st, 1863, then Proclamation would go into effect.

The Emancipation Proclamation changed the meaning and purpose of the Civil War. The war was no longer just about preserving the Union - it was also about freeing the slaves. Foreign powers such as Britain and France lost their enthusiasm for supporting the Confederacy.
