The Haitian Revolution was the first successful slave revolt in history. Samuel Farber recently wrote an interesting article for the Jacobin exploring the rebellion's far-reaching effects on Cuban society. Two key takeaways: The 1791 rebellion made Cuban slaveholders extremely afraid. It also transformed the island into the sugar-slave capital of the world. 

The Jacobin reports:

"As slave insurgency ground Haitian farming and manufacture to a halt, sugar production took off in neighboring Cuba, as did a new plantation system of coffee cultivation established by white refugees from Saint Domingue in the eastern part of the island. In the thirty years that followed, approximately 325,000 Africans were brought to Cuba as slaves, more than four times the number brought in the three decades prior. By 1804, Cuban sugar exports had risen from 15,000 metric tons a year to 40,000. Between 1791 and 1810, the population of Havana doubled. Cuba’s economy and society were rapidly transformed."
