He had originally included language condemning the British promotion of the slave trade (even though Jefferson himself was a slave owner).
This criticism of the slave trade was removed in spite of Jefferson’s objections.
In 1774 he wrote “A Summary View of the Rights of British America”?
which became a very powerful argument of American terms for settlement with Britain.
One of the most widely held misconceptions about the Declaration of Independence is that it was signed on July 4, 1776.
In fact, independence was formally declared on July 2, 1776, a date that John Adams believed would be “the most memorable epocha in the history of America.” On July 4, 1776, Congress approved the final text of the Declaration. After Jefferson wrote his first draft of the Declaration, the other members of the Declaration committee and the Continental Congress made 86 changes to Jefferson’s draft, including shortening the overall length by more than a fourth.
It would definitely light a fire and help to speed the way to independence.
Jefferson drew heavily on George Mason’s Virginia Declaration of Rights and much of his own work on the Virginia Constitution in his efforts to write the Declaration of Independence.
Instead, there are a few handwritten words that say, "Original Declaration of Independence/ dated 4th July 1776".
No one knows who wrote this, but it was probably added as a label when the document was rolled up for storage many years ago.
