The notion of vampirism has existed for millennia; cultures such as the Mesopotamians, Hebrews, Ancient Greeks, and Romans had tales of demons and spirits which are considered precursors to modern vampires. However, despite the occurrence of vampire-like creatures in these ancient civilizations, the folklore for the entity we know today as the vampire originates almost exclusively from early 18th century Southeastern Europe, when verbal traditions of many ethnic groups of the region were recorded and published. In most cases, vampires are revenants of evil beings, suicide victims, or witches, but they can also be created by a malevolent spirit possessing a corpse or by being bitten by a vampire. Belief in such legends became so pervasive that in some areas it caused mass hysteria and even public executions of people believed to be vampires. I've come to my conclusion, no, there's no such thing as vampires. But there were.
