After the slave revolt the new leaders hunted down and exterminated all the whites. Even the ones the new leaders had invited to settle there.
And when they ran out of whites to kill, they started killing each other. Literally. The first president of Haiti proclaimed himself "Emperor for Life. This infuriated two of his former allies and "leaders" of the revolution, so they killed him.
Those two each claimed the presidency as his successor, set up rival governments in the north and south, and started warring with each other. The one in the north declared himself "King" and the one in the south picked "President for Life." The southern "president for life" died in 1818 and his hand picked successor (another leader of the revolution) tried to take control of the north. He succeeded when the "king" committed suicide there a few months later to avoid being captured by the mob in a coup, and then tried to take over the Dominican half of the island. That war lasted until 1843 when he too was ousted in a coup by a former subordinate from the coup against the first emperor...who was ousted a year later by another former revolutionary leader who had been given a title of nobility by the northern "King."
