The Haitian Revolution was an important time in Haiti for the slaves. The slaves fought for their freedom against the white leaders and masters. The slaves in Haiti also practiced their own rituals and religious ceremonies during their secret meetings to plan their mass insurrection.
The slaves would make sacrificial offerings and also they swore an oath of secrecy and revenge for theirtravesties. The summation of these practices would later become known as Voodoo. When someone thinks of Voodoo, their mind instantly jumps to a picture of the tiny dolls that people stick with pins with the beleif that harm will come to whomever the Voodoo doll isconnected. My mind also went in the same direction when Voodoo was first referenced in the Haitian Revolution, but it is actually far deeper and important to their culture than simply soft dolls.The slaves practiced this as a religion, not a hobby or simply in ceremony (though the rituals often included ceremonies). Vodouisants (the name given to those who practice Voodoo) believed in an all powerful deity named Bondye. This being was beleived to be the highest god,
although Haitian Vodouisants also believed in lowerlevels of gods referred to as misté. Also known as Loa, Haitians aimed prayers toward these lesser gods due to the fact that the great Bondye was believed to be untouchable. Voodoo is very important to Haitian slaves because it gave them something to pray to and believe in. Their rituals in the dead of night gave them their own culture to oppose their masters.
