But not until two years after a group of states threw off the rule of Washington D.C. *THAT* is when it suddenly became necessary to look after their rights and interests.
Prior to that, they didn't need their rights and interests looked after.
I have no idea of what you point is here. Not quite two years into the rebellion, Lincoln issues his Emancipation Proclamation as a war-time measure to free Southern slaves that might have been used to further the rebel war effort. Nowhere in that document is there anything about "rights" for the freed slaves. In fact the 3/5ths rule remained in effect until the 14the Amendment. But as free men and women then the newly emancipated slaves did count as a whole person because they were no longer property.
For later
