Zombie is a fictional undead being created through the reanimation of a human corpse. Zombies are most commonly found in horror, science fiction, and fantasy literature. The term comes from Haitian Creole dialect. In Haitian folklore, a zombie is a dead body reanimated through various methods, most commonly magic. Modern depictions of zombies do not necessarily involve magic but often invoke science fictional methods such as radiation, mental diseases, viruses, and scientific accidents. Although the Haitian zombies were mind-controlled slaves of the wizard who raised them, popular culture since the 1970s has recharacterized zombies' nature as that of ferocious wild beasts of prey, driven by a single-minded desire to eat human flesh.
After the Big Bubble burst, zombies became popular with factory and mill owners in the United States, as they would work for no pay. Down-and-out people even volunteered to become zombies, as zombies felt no pain or sadness.
