Answer:
Jefferson's missing paragraph was the one in the original draft of the Declaration of Independence that denounced the slave trade and slavery in the United States.
The paragraph was removed from the final version of the document due to objections from Southern delegates who believed it would undermine their interests.
The paragraph read: 'He [the King of Great Britain] has waged cruel war against human nature itself, violating its most sacred rights of life and liberty in the persons of a distant people who never offended him, captivating & carrying them into slavery in another hemisphere, or to incur a miserable death in their transportation thither.
This piratical warfare, the opprobrium of infidel powers, is the warfare of the Christian King of Great Britain.
Determined to keep open a market where MEN should be bought & sold, he has prostituted his negative for suppressing every legislative attempt to prohibit or restrain this execrable commerce.'
