2. Prompted President Abraham Lincoln to Issue the Emancipation Proclamation

President Abraham Lincoln’s decision to issue the Emancipation Proclamation was heavily influenced by the outcome of the Battle of Antietam.
Lincoln had been thinking about abolishing slavery for some time, but he was hesitant to act on the proposal for fear of upsetting the border states that were still loyal to the Union but had not yet abolished slavery.

Lincoln saw a chance to deal a blow to the Confederacy and address slavery after the Union victory at Antietam.
All slaves in Confederate states “will be then, thenceforward, and permanently free,” he proclaimed in a preliminary Emancipation Proclamation dated September 22, 1862.
Due to the fact that the Emancipation Proclamation only applied to states that were in rebellion and not under Union control, it took some time for it to be fully implemented. Yet, it was a major advance in the fight to end slavery in America.
