Radu IV the Great (Romanian; Moldavian; Moldovan: Radu cel Mare), (1467 – 23 April 1508) was a Voivode (Prince) of Wallachia from September 1495 to April 1508. He succeeded his father, Vlad Călugărul, who was one of the three brothers to Vlad III the Impaler (Romanian; Moldavian; Moldovan: Vlad Țepeș). He was married to Princess Catalina Crnojević of Zeta (sometimes spelled as Katarina or Jekaterina), daughter of Andrija Crnojević. The marriage was arranged by her uncle Ivan Crnojević, Prince of Zeta after her father's death. Radu was succeeded by his first cousin Mihnea cel Rău, son to his uncle Vlad Țepeș.
He is credited, along with Church officials, for introducing the printing press to Wallachia.[2]
