The … Revolution created the second independent country in the Americas after the United States became independent in 1783.
An adjective has been omitted from the preceding quote; which nation does the term describe?
Answer: Haiti.
Haitian was removed from the quote. The Haitian Revolution established the second independent American nation after the U.S. in 1783. Haiti, formerly St. Domingue, was a profitable French colony reliant on slave labour. The French Revolution sparked a slave revolt in 1791, led by Toussaint L’Ouverture. U.S. leaders, many of whom were slaveowners, were ambivalent about the revolt. Initially, they aided its suppression but later supported L’Ouverture. Due to policy shifts and domestic issues, the U.S. didn’t recognise Haiti’s independence until 1862. Jefferson initially aided L’Ouverture but later isolated Haiti.
