Zombies are fictional undead creatures, typically depicted as mindless, reanimated human corpses with a hunger for human flesh. Zombies are most commonly found in horror and fantasy genre works. Some depictions are inspired by Haitian folklore, while modern depictions typically do not have that same direct connection. Zombies have a complex literary heritage, with antecedents ranging from Richard Matheson and H. P. Lovecraft to Mary Shelley‘s Frankenstein drawing on European folklore of the undead. George A. Romero‘s reinvention of the monster for his 1968 film Night of the Living Dead led to several zombie films in the 1980s and a resurgence of popularity in the 2000s. The “zombie apocalypse” concept, in which the civilized world is brought low by a global zombie infestation, became a staple of modern popular art.
