You do realize that it took an amendment to the Constitution before that happened, it didn't just fade away?

All thirteen of the original states had slavery at one time some before the revolution some after. It ended in more than half without and amendment.

The whole idea that Slavery would have ended on it's own any way, negates the very reasons for the democrat's rebellion against The United States.

They did not rebel. They parted company. The south did not know when or if slavery would end. If they really wanted to keep slavery indefinitely they could have just stayed in the Union and helped pass the Corwin Amendment.

Show me one southern state in 1860 that was run by Republicans and seceded from the United States for the purposes of abolishing slavery as it existed in the Constitution, show me just one, that's all I ask and if you can, I'll admit defeat honorable

I never claimed there was one. The new party "Republican" reason for being was to end slavery and centralize government. Therefore if the Republican party got control of the federal government they would soon be able to wrestle away state powers that the Constitution protected. And, in this case first and foremost it "was" slavery. As I am sure you know the Constitution grants the federal government certain powers and all others are those of the states. We all know that since the WBTS ended those limited powers that are the domain of the the federal government, have now became ever limitless powers.

They did not rebel. They parted company. The south did not know when or if slavery would end. If they really wanted to keep slavery indefinitely they could have just stayed in the Union and helped pass the Corwin Amendment.

The Corwin amendment specifically did not address the one issue that the southern leadership was most interested in, the expansion of slavery into the territories. They knew that unless they could take their slaves with them into the territories then the states that resulted could not be slave states. So instead they rebelled and adopted a constitution that protected slavery expansion and slave imports in a way the Corwin amendment could never do.
