The curse of the pharaohs or the mummy's curse or the Curse of King Tut is a curse alleged to be cast upon anyone who disturbs the mummy of an ancient Egyptian, especially a pharaoh. This curse, which does not differentiate between thieves and archaeologists, is claimed to cause bad luck, illness, or death. Since the mid-20th century, many authors and documentaries have argued that the curse is 'real' in the sense of having scientifically explicable causes such as bacteria, fungi or radiation. However, the modern origins of Egyptian mummy curse tales, their development primarily in European cultures, the shift from magic to science to explain curses, and their changing uses—from condemning disturbance of the dead to entertaining horror film audiences—suggest that Egyptian curses are primarily a cultural, not scientific, phenomenon.
