EXPLANATIONS BELOW
Concept note-1: -President Abraham Lincoln issued the Emancipation Proclamation on January 1, 1863, as the nation approached its third year of bloody civil war. The proclamation declared “that all persons held as slaves” within the rebellious states “are, and henceforward shall be free."
Concept note-2: -By freeing slaves in the Confederacy, Lincoln was actually freeing people he did not directly control. The way he explained the Proclamation made it acceptable to much of the Union army. He emphasized emancipation as a way to shorten the war by taking Southern resources and hence reducing Confederate strength.
Concept note-3: -The Emancipation Proclamation, officially Proclamation 95, was a presidential proclamation and executive order issued by United States President Abraham Lincoln on January 1, 1863, during the Civil War.
