Emancipation Proclamation
In September of 1862, after the Union's victory at Antietam, Lincoln issued a preliminary decree stating that, unless the rebellious states returned to the Union by January 1, freedom would be granted to slaves within those states. The decree also left room for a plan of compensated emancipation. No Confederate states took the offer, and on January 1 Lincoln presented the Emancipation Proclamation. The proclamation declared, "all persons held as slaves within any States, or designated part of the State, the people whereof shall be in rebellion against the United States, shall be then, thenceforward, and forever free."
