Unlike the american revolution, the haitian revolution was a) unsuccessful. b) led by masses of poor people. c) fought against the united states. d) achieved through armed resistance.

B Led by massed of poor people
Here's why:
The Haitian Revolution has often been described as the largest and most successful slave rebellion in the Western Hemisphere. It was a successful anti-slavery by self-liberated slaves against French colonial rule in Saint-Domingue. The ideas of the French Enlightenment philosophes strongly influenced the American revolutionaries. The 13 eastern colonies demanded democratic government, and went to war against Britain in 1775. This lead to the signing of the Declaration of Independence in 1776.
