The Emancipation Proclamation alone makes America the most powerful nation on earth.

1. The Emancipation Proclamation allowed slaves in Northern States to remain property.

Those states in rebellion were not under his authority until after the civil war, so nobody was freed in those states, either. The Emancipation Proclamation did not cause a slave rebellion, which appeared to be its major intent.

It did undercut the Dred Scott Decision where southern slaves were concerned. But slaves in non rebellion states were still required to be rounded up and returned to those who owned them.

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; and the Executive Government of the United States, including the military and naval authority thereof, will recognize and maintain the freedom of such persons, and will do no act or acts to repress such persons, or any of them, in any efforts they may make for their actual freedom.

The Constitution is the Cornerstone of what we are, and it codified the right of the rich to own people. It required a civil war, the thirteenth, and fourteenth amendments to change that. And it wasn't until the Civil Rights Act of 1964 that the major ty the work was finished.
