I was watching a CNN special on Africa and slavery. I got me thinking, what if when the U.S. Constitution and the Bill of Rights were being written; OTL's 13th, 14th and 15th Amendments were automatically included with the original bill of rights, creating the "Original 13 Amendments of the Bill of Rights." What type of butterflies would this create? What would the demographics of the United States look like today? Would the African American population be smaller? Would there even had been a civil war? What would the United States appear to be like culturally?
