This is not true. The last slaves in the United States were set free by the thirteenth amendment in Delaware, IIRC. Emancipation Day could make sense as the last slaves freed by the emancipation proclamation took place on that date.
A common misconception holds that the Emancipation Proclamation freed all slaves in the United States, or that the General Order No. 3 on June 19, 1865, marked the end of slavery in the United States. In fact, the Thirteenth Amendment, ratified and proclaimed in December 1865, was the article that made slavery illegal in the United States nationwide, not the Emancipation Proclamation.[6][7][8][9]
Another common misconception is that it took over two years for news of the Emancipation Proclamation to reach Texas, and that slaves did not know they had already been freed by it. In fact, news of the Proclamation had reached Texas long before 1865, and many slaves knew about Lincoln's order emancipating them, but they had not been freed since the Union army had yet to reach Texas to enforce the Proclamation. Only after the arrival of the Union army and General Order No. 3 was the Proclamation widely enforced in Texas.
Regardless, people have been calling it Juneteenth for over a hundred years, it was made a national holiday as Juneteenth, I'm gonna keep calling it that.
In Texas and maybe celebrated in other places(I haven't done the research) this is true. For a large swath of the United States it was obscure or unknown. Most of us learned about the Emancipation Proclamation though. Making Juneteenth a holiday rather than the Date of the Emancipation Proclamation is odd to me. It is as odd to me as say, celebrating Independence Day on the date the last colony got word of the signing on, hypothetically, July 5th.
The Emancipation Proclamation freed very few slaves. The order did not apply to areas of the Union which still had slaves, nor did it apply to areas of the Confederacy occupied by the Union. Although, it did apply to unoccupied areas of the Confederacy. The government of the Confederacy was unlikely to follow an order issued by the Union during the Civil War.
It may have encouraged some slaves in the Confederacy to flee, if they found out about it.
>The last slaves in the United States were set free by the thirteenth amendment
Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.
Section 2
Congress shall have power to enforce this article by appropriate legislation.
You may be surprised to learn that, coincidentally, America has more people in prison than anywhere else.
General Order No. 3 - June 19, 1865
Thirteenth Amendment - December 6, 1865
