That on the first day of January in the year of our Lord, one thousand eight hundred and sixty-three, all persons held as slaves within any State, or designated part of a State, the people whereof shall then be in rebellion against the United States shall be then, thenceforward, and forever free; ... Emancipation Proclamation - Wikipedia, the free encyclopedia The Emancipation Proclamation consists of two executive orders issued by United States President Abraham Lincoln during the American Civil War. The first one, issued September 22, 1862, declared the freedom of all slaves in any state of the Confederate States of America that did not return to Union control by January 1, 1863. The second order, issued January 1, 1863, named ten specific states where it would apply. Lincoln issued the Executive Order by his authority as "Commander in Chief of the Army and Navy" under Article II, section 2 of the United States Constitution.more Additionally, the Proclamation provided the legal framework for the emancipation of nearly all four million slaves as the Union armies advanced, and committed the Union to ending slavery, which was a controversial decision even in the North. Hearing of the Proclamation, more slaves quickly escaped to Union lines as the Army units moved South. As the Union armies advanced through the Confederacy, thousands of slaves were freed each day until nearly all (approximately 4 million, according to the 1860 census) were freed by July 1865. Near the end of the war, abolitionists were concerned that while the Proclamation had freed most slaves as a war measure, it had not made slavery illegal. Several former slave states had already passed legislation prohibiting slavery; however, in a few states, slavery continued to be legal, and to exist, until December 18, 1865, when the Thirteenth Amendment was enacted.
