Vampires are mythological or folkloric beings that subsist on human and/or animal lifeforce. In most cases, they are reanimated corpses who feed by draining and consuming the blood of living beings. In folklore, the term usually refers to the blood-drinking humans of Eastern European legends, but the term is often applied to similar legendary creatures from other regions and cultures.
The characteristics of vampires vary widely among these different traditions. Some cultures also have stories of non-human vampires, including real animals such as bats, dogs, spiders, and mythical creatures such as the chupacabra. Vampires are a frequent subject of fictional books and films, although fictional vampires are often attributed traits distinct from those of folkloric vampires.
In March 2007, self-proclaimed vampire hunters broke into the tomb of Slobodan Milosevic, former president of Serbia and Yugoslavia, and staked his body through the heart into the ground. Although the group involved claimed this act was to prevent Milosevic from returning as a vampire, it is not known whether those involved actually believed this could happen or if the crime was simply politically motivated.
