"A letter sent by James Madison on November 25, 1820, to the Marquis de Lafayette discussed the debate over admitting Missouri as a slave state and the confusion caused by the different rights of "free people of color" in various states. He deplored the "various disqualifications which degrade them from the rank & rights of white persons". Dismayed by the growing divisiveness in the nation, which he had helped to found, Madison added, "All these perplexities develop more and more, the dreadful fruitfulness of the original sin of the African trade"."
