Petro loa

Petro (Haitian Creole:Petwo), sometimes as Pethro, is a family of loa (spirits) in Haitian Vodou religion. The story is that they originated in Haiti, under the harsh conditions of slavery. The term petro can also refer to a drum used in the music of Haiti. "Petro" loas are often considered to be "angry" or demon loa, used in "black magic". They are the "newer" loa that can relate to the harsh, unimaginable conditions that slaves had to endure.
