Toussaint Louverture led a successful slave revolt and emancipated the slaves in the French colony of Saint-Domingue (Haiti). A formidable military leader, he turned the colony into a country governed by former black slaves as a nominal French protectorate and made himself ruler of the entire island of Hispaniola.
It decided that the "once free always free" was no longer valid and did not need to be honored and Dred Scott and his family would remain slaves until freed by their masters. It became one of the main causes of the American Civil War. Hope this helped!
