Final answer:
The Haitian Revolution led to an influx of French refugees, including enslaved and free people of color, to New Orleans. This caused concern among Americans who feared the spread of radicalism. It also inspired fear among white people and slaveholders in the southern United States.
Step-by-step explanation:
The Haitian Revolution had a significant impact on New Orleans. Following the revolution, many white refugees from Haiti and other French West Indian islands, as well as enslaved and free people of color, migrated to the United States and settled in New Orleans.
This influx of French migrants raised fears among some Americans that they would bring radicalism to the United States. Additionally, the revolution in Haiti inspired fear among white people and slaveholders in the southern United States as it showed that a successful slave uprising was possible.
