His Proclamation didn’t free any one. It proposed freeing slaves in the South only-no mention of the North. (Ths South had already seceded and Abe had no authority there.)
The 13th Amendment later abolished slavery whem ratified in the latter part of 1865.
“Ths South had already seceded and Abe had no authority there.” LOL! If only it had been that simple. Abe didn’t see it that way nor did he recognize the Southern states secession, thus, in his mind, he did have the authority. It sucks, I know, but that’s the long and short of it.
Note the repeated use of the word “free” or “freed”.
The Emancipation Proclamation is an executive order issued by United States President Abraham Lincoln on January 1, 1863, during the American Civil War using his war powers. It was not a law passed by Congress. It proclaimed the freedom of slaves in the ten states then in rebellion, thus applying to 3.1 million of the 4 million slaves in the U.S. at that time. The Proclamation immediately freed 50,000 slaves, with nearly all the rest (of the 3.1 million) freed as Union armies advanced. The Proclamation did not compensate the owners, did not itself outlaw slavery, and did not make the ex-slaves (called freedmen) citizens.[1]
