This story reads as the one about Matthias Corvinus https://en.wikipedia.org/wiki/Matthias_Corvinus and Vlad Tepes, https://en.wikipedia.org/wiki/Vlad_the_Impaler or Vlad the Impaler., or Vlad Dracula.
After the Ottoman Empire attacked Vlad Tepes from the South, Matthias Corvinus, one of the recognized most educated sovereign in his times, start spreading rumors that Vlad sucks blood from his peasants, to spread demoralization, so he can expand to the East on account of Vlad Tepes’ lands.
