Around the world black magic has been, and is practiced in many cultures. Maybe even most cultures. Native American indians still use medicine men, and spirit guides to advise them, and to fix problems in their tribe. In the USA in Salem and many southern states, witchcraft – practicing black magic and doing anything attributed to the supernatural was punished with the most horrible form of torture resulting in death. Burning people alive was popular. Cuba and other Spanish speaking places have Santa Ria. It was big in Miami, Florida when I lived there. My roommate actually found a small black coffin with small people made out of yarn and pins through their bodies while out on a run near a railroad track. Seances are popular around the world – in which dead people or spirits are contacted through a medium. Evidence of belief in black magic is evidenced by a rather strong belief in ghosts. This is easily seen around the country in the form of spirit houses.
