The Emancipation Proclamation
      Due to the inconclusive battle of Antietam, President Abraham Lincoln had the courage to create the Emancipation Proclamation to free the slaves of the south. the idea was that if the south did not surrender soon, then their slaves would, according to the Union, be free. Lincoln assumed that with their slaves at stake, the south would surrender an put at stop to the bloody Civil War. In actuality, the effect was far from the intent. The people of the south were absolutely outraged. They considered themselves to be their own nation and therefore believed that Abraham Lincoln had no governance over them. As a result, the Confederates fought harder and with more fury and passion. The Emancipation Proclamation gave them even more of a cause to fight for. There was also another exception to the proclamation. It only applied to the slaves living in the rebel states. For the four states that did not secede from the Union, Delaware, Maryland, Kentucky, and Missouri, their slaves would not be freed because the new law did not apply to them.
