Slavery was made in illegal in the US by a presidential proclamation — frank
No, actually it wasn't. The Proclamation states:
"Now, therefore I, Abraham Lincoln, President of the United States, by virtue of the power in me vested as Commander-in-Chief, of the Army and Navy of the United States in time of actual armed rebellion against the authority and government of the United States, and as a fit and necessary war measure for suppressing said rebellion, do, on this first day of January, in the year of our Lord one thousand eight hundred and sixty-three, and in accordance with my purpose so to do publicly proclaimed for the full period of one hundred days, from the day first above mentioned, order and designate as the States and parts of States wherein the people thereof respectively, are this day in rebellion against the United States, the following, to wit:
Arkansas, Texas, Louisiana, (except the Parishes of St. Bernard, Plaquemines, Jefferson, St. John, St. Charles, St. James Ascension, Assumption, Terrebonne, Lafourche, St. Mary, St. Martin, and Orleans, including the City of New Orleans) Mississippi, Alabama, Florida, Georgia, South Carolina, North Carolina, and Virginia, (except the forty-eight counties designated as West Virginia, and also the counties of Berkley, Accomac, Northampton, Elizabeth City, York, Princess Ann, and Norfolk, including the cities of Norfolk and Portsmouth[)], and which excepted parts, are for the present, left precisely as if this proclamation were not issued.
And by virtue of the power, and for the purpose aforesaid, I do order and declare that all persons held as slaves within said designated States, and parts of States, are, and henceforward shall be free; and that the Executive government of the United States, including the military and naval authorities thereof, will recognize and maintain the freedom of said persons."
Only the areas of the South that were in rebellion had their slaves freed, which means that in the Union states where there were slaves and in the captured areas of the South, the slaves remained slaves. So, the slaves were freed in the areas where Lincoln did not control and in the areas he did contol they were left enslaved.
Curious.
One should read this history. The basis for the Proclamation was to recast the Civil War as one over slavery as opposed to simply keeping the Union intact, so as to remove any willingness of England or France to diplomatically intervene and give credence to the Confederacy as a sovereign nation.
So obvious was Lincoln's intent that he withheld the Proclamation for some time until he he could show he was not losing the war and trying to use it just to derail the South's best strategy. He waited until he defended the southern attack directly against the Army of the Potomac just outside the nation's capital in the battle of Antietam before he issued the Proclamation, presenting it on the heels of a victory, although it wasn't quite as decisive as he had wanted.
This is to say the Proclamation was a strategic manuever.
The 13th Amendment illegalized slavery, not the declaration of a single man over a territory in rebellion that he did not control.
