The legend of Count Dracula was based on Vlad Tepes, the fifteenth century ruler of the Romanian State of Sighisoara, just south of Transylvania. Vlad assumed the name Dracula, meaning "Son of a Dragon", because he was a member of the Roman Order of the Dragon, set up to fight the Turks.
Vlad Tepes used to drink the blood of his enemies to instil fear - not uncommon at this time. He was also a very strict ruler who used to punish criminals by impaling them. In 1897 Bram Stoker adapted Vlad's legend for his famous novel.
