The Ottoman Empire's worst enemy in the Balkans became, five centuries later, a vampire. The historical Vlad III Tepes was a Wallachian voivode at war with Mehmed II. The undead Count is a literary costume fitted to him in 1972.
Documented
The sultan's own historians recorded it
June 17, 1462: Vlad's night attack on Mehmed II's camp, the voivode infiltrating in Turkish disguise and hunting the sultan's tent, hitting the grand viziers' by mistake. The campaign around it stands on primary sources from both sides. Vlad's own letter to Matthias Corvinus counts 23,844 killed. Chalkokondyles records Mehmed at the forest of stakes saying no one could take the country of a man with so diabolical an understanding of how to govern. Konstantin Mihailovic, a Serbian janissary, wrote the Danube crossing from inside the Ottoman army. Vlad had refused the jizya since 1459, killed the sultan's envoys, and turned Hamza Pasha's ambush around at Giurgiu.
Assessment: The campaign, the letter, the stakes and the Ottoman retreat are documented in enemy and allied chronicles alike. The death tolls are wartime numbers, and scholars still audit the scale of the impalements (Cazacu, 2017), but the forest of stakes is not legend; it is in the other side's own history.
Stories
The horror bestseller of the fifteenth century
Vlad was famous before he was dead. German pamphlets out of Nuremberg (1488) sold his atrocities to the new printing-press public, complete with a woodcut of the Impaler dining among his stakes; the Russian Skazanie o Drakule voevode circulated in Muscovy within a generation. Both genres pushed the same product: a Christian prince whose cruelty made the Turk look moderate. Inside Romania the story inverted: Vlad became the nationalist pillar who made an empire respect a small country.
Assessment: The pamphlets and the Skazanie are documented early print and manuscript culture, propaganda by design, and the scholarship (Florescu and McNally, Treptow, Cazacu) separates the marketing from the man. Both portraits were useful to someone, which is why both survived.
Interesting claims
The name was stolen from a footnote
Stoker never read the chronicles. His working notes, now at the Rosenbach, show he took exactly one thing from William Wilkinson's 1820 Account of the Principalities of Wallachia and Moldavia: the name, plus Wilkinson's gloss that Dracula in the Wallachian language means devil. There is no evidence Stoker knew about the stakes, Targoviste, or Mehmed II. The weld between voivode and vampire was performed in 1972 by Florescu and McNally's In Search of Dracula, a publishing triumph that retrofitted five hundred years of folklore onto a library footnote.
Assessment: Documented in Stoker's own notes: a name and a gloss, nothing else. The impaling Count is twentieth-century grafting, which makes him superb myth and poor history, and the two have been billed as one product ever since.

Worth asking
Vlad impaled tens of thousands and never drank anyone's blood. The Count drank blood and never impaled anyone. Which monster is the fiction?
