The Declaration of Independence was a huge step towards America's independence (as the name may give away.) Though it excluded many, it did not address women, nor did it recognize the rights of enslaved African Americans. It was also written by Thomas Jefferson, with the help of Benjamin Franklin and John Adams.
Through Lord Dunmore's Proclamation slaves were allowed to fight in the continental army in exchange for freedom. Though people of color were still persecuted against, slavery would start to be abolished in the northern states. This is what started what would be the push for civil rights.
The Treaty of Paris which was signed by representatives of King George III of Britain and representatives of the United States of America was what ended the revolutionary war and recognized American independence. The Continental Congress named a five-member commission to negotiate a treaty-John Jay, Henry Laurens, John Adams, Thomas Jefferson, and Benjamin Franklin. Though, Adams, Franklins, and Jay conducted negotiations.
