Answer:
The Haitian Revolution played a big role in history since it was the first country in the entire world where slaves successfully gained their freedom through force where they were able to run their country without the interference of colonizers. As the news got out about Haiti's sucessful revolution it influenced other colonized nations primarily those in Latin and South America to do the same while in the US tried to hide the news by cutting ties with Haiti in fear that the slaves they owned would do the same, despite these efforts, rebellions still occured which many if not all of them being unsuccessful and called for stricter slavery laws, although the Haitian Revolution allowed for the expansion of slavery in the US as the Louisiana Purchase was sold by France during the Revolution.
