I believe he freed most of his slaves during his lifetime after retirement, which ultimately led to his death since he was too old to preform the daily upkeep at Mount Vernon. But I could be incorrect on that…
Both Jefferson and Washington didn’t just keep slaves - they bred them from their own loins.
As was the custom of the day, and we can point to several accepted, unspoken practices of the time that today we find repulsive, such as pedophilia in the British Army and the like…But that changes nothing into what was the insight into their views
Washington I can’t speak for, but I’ve never heard that though it’s pretty clear he was in love with another woman who wasn’t his wife, but she was an upper class white woman…
Yes, Jefferson had an affair with Sally Hemings, but it appears to have entailed a strong emotional attachment and she was more of a mistress than a “breader”…
Of course he was a hypocrite to some extent, but there is evidence that he actually attempted to force a gradual ending of slavery via something he did legislatively, but it was very subtle and is often missed. In any case, he did speak out against slavery:
Thomas Jefferson wrote “I tremble for my country when I reflect that God is just: that his justice cannot sleep forever.”
Jefferson was very outspoken against slavery. In 1779, Jefferson proposed a law that was intended to provide for gradual emancipation in Virginia. In 1787, he published the most eloquent denunciation of slavery of any of the founders in “Notes on the State of Virginia.” In 1807, as President, he publicly supported the abolition of the slave trade.
Jefferson’s first draft of the Declaration of Independence read that blacks were “men” and slavery was wrong.
- “He [the king of 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 and carrying them into slavery in another hemisphere…. Determined to keep open a market where MEN should be bought and sold, he has prostituted his negative for suppressing every legislative attempt to prohibit or to restrain this execrable commerce.”
