What Is A Zombie?

A zombie is a reanimated human corpse. Stories of zombies originated in the Afro-Caribbean spiritual belief system of Vodou, which told of the people being controlled as workers by a powerful sorcerer. Zombies became a popular device in modern horror fiction, largely because of the success of George A. Romero's 1968 film Night of the Living Dead.

There are several possible etymologies of the word zombie. One possible origin is jumbie, the West Indian term for "ghost". Another is nzambi, the Kongo word meaning "spirit of a dead person." According to the Merriam-Webster dictionary, the word entered English circa 1871; it's derived from the Louisiana Creole or Haitian Creole zonbi, which in turn is of Bantu origin. A zonbi is a person who is believed to have died and been brought back to life without speech or free will. It is akin to the Kimbundu nzúmbe ghost.

According to the tenets of Vodou, a dead person can be revived by a bokor or Voodoo sorcerer. Zombies remain under the control of the bokor since they have no will of their own. "Zombi" is also another name of the Vodou snake god Damballah Wedo, of Niger-Congo origin; it is akin to the Kongo word nzambi, which means "god". There also exists within the voudon tradition the zombi astral which is a human soul that is captured by a bokor and used to enhance the bokor's power.

Several decades later, Wade Davis, a Harvard ethnobotanist, presented a pharmacological case for zombies in two books, The Serpent and the Rainbow (1985) and Passage of Darkness: The Ethnobiology of the Haitian Zombie (1988). Davis traveled to Haiti in 1982 and, as a result of his investigations, claimed that a living person can be turned into a zombie by two special powders being entered into the blood stream (usually via a wound). The first, coup de poudre (French: 'powder strike'), includes tetrodotoxin (TTX), the poison found in the pufferfish. The second powder is composed of dissociatives such as datura. Together, these powders were said to induce a death-like state in which the victim's will would be entirely subject to that of the bokor. Davis also popularized the story of Clairvius Narcisse, who was claimed to have succumbed to this practice.

In the Middle Ages, it was commonly believed that the souls of the dead could return to earth and haunt the living. The belief in revenants (someone who has returned from the dead) is well documented by contemporary European writers of the time, such as William of Newburgh and Walter Map. According to the Encyclopedia of Things that Never Were[6], particularly in France during the Middle Ages, the revenant rises from the dead usually to avenge some crime committed against the entity, most likely a murder. The revenant usually took on the form of an emaciated corpse or skeletal human figure, and wandered around graveyards at night. The "draugr" of medieval Norse mythology were also believed to be the corpses of warriors returned from the dead to attack the living. The zombie appears in several other cultures worldwide, including China, Japan, the Pacific, India, Persia, the Arabs, and the Native Americans.

The Epic of Gilgamesh of ancient Sumer includes a mention of zombies. Ishtar, in the fury of vengeance says:

Father give me the Bull of Heaven,
So he can kill Gilgamesh in his dwelling.
If you do not give me the Bull of Heaven,
I will knock down the Gates of the Netherworld,
I will smash the doorposts, and leave the doors flat down,
and will let the dead go up to eat the living!
And the dead will outnumber the living!

Modern zombies, as portrayed in books, films, games, and haunted attractions, are quite different from both voodoo zombies and those of folklore. Modern zombies are typically depicted in popular culture as mindless, unfeeling monsters with a hunger for human brains and flesh, a prototype established in the seminal 1968 film Night of the Living Dead. Typically, these creatures can sustain damage far beyond that of a normal, living human (generally these can only be killed by a wound to the head, such as a headshot) and can pass whatever syndrome that causes their condition onto others.

Usually, zombies are not depicted as thralls to masters, as in the film White Zombie or the spirit-cult myths. Rather, modern zombies are depicted in mobs and waves, seeking either flesh to eat or people to kill or infect, and are typically rendered to exhibit signs of physical decomposition such as rotting flesh, discolored eyes, and open wounds, and moving with a slow, shambling gait. They are generally incapable of communication and show no signs of personality or rationality, though George Romero's zombies appear capable of learning and very basic levels of speech as seen in the films Day of the Dead and Land of the Dead.

Modern zombies are closely tied to the idea of a zombie apocalypse, the collapse of civilization caused by a vast plague of undead. The ideas are now so strongly linked that zombies are rarely depicted within any other context.
