A zombie (Haitian Creole: zonbi; North Mbundu: nzumbe) is an animated corpse brought back to life by mystical means, such as witchcraft. The term is often figuratively applied to describe a hypnotized person bereft of consciousness and self-awareness, yet ambulant and able to respond to surrounding stimuli. Since the late 19th century, zombies have acquired notable popularity, especially in North American and European folklore.
In modern times, the term "zombie" has been applied to an undead being in horror fiction, largely drawn from George A. Romero's 1968 film Night of the Living Dead. They have appeared as plot devices in various books, films, video games and in television shows.
The word zombie is not used in Night of the Living Dead, but was applied later by fans. The monsters in the film and its sequels, as well as its many inspired works, are usually hungry for human flesh although Return of the Living Dead introduced the popular concept of zombies eating brains. Sometimes they are victims of a fictional pandemic illness causing the dead to reanimate or the living to behave this way, but often no cause is given in the story. Although this modern monster bears some superficial resemblance to the Haitian zombie tradition, its links to such folklore are unclear and many consider George A. Romero to be the progenitor of this creature. Zombie fiction is now a sizeable sub-genre of horror, usually describing a breakdown of civilization occurring when most of the population become flesh-eating zombies.
