 Historically, the name "Dracula" is the given name of Vlad Țepeș' family, a name derived from a secret fraternal order of knights called the Order of the Dragon, founded by Sigismund of Luxembourg (king of Hungary and Bohemia, and Holy Roman Emperor) to uphold Christianity and defend the Empire against the Ottoman Turks.Vlad II Dracul, father of Vlad III, was admitted to the order around 1431 because of his bravery in fighting the Turks and was dubbed Dracul (dragon or devil) thus his son became Dracula (son of the dragon).From 1431 onward, Vlad II wore the emblem of the order and later, as ruler of Wallachia, his coinage bore the dragon symbol.
