the Haitian revolution began because it was unfair how the slaves were being treated badly. they had to work, and if they did something accidentally wrong, they would get hit by a slash or get beaten up. the slaves thought this was unfair, and they were right. soon they had done these steps to declare freedom: Haitian Revolution
The slaves' plan to declare freedom was:
get the slave owner's slash
hit the slave owner with the slash
then burn the plantation
Half of Haity was owned by France and the other half by Spain.
