Zoltán of Hungary

Zoltán (Hungarian pronunciation: [ˈzoltaːn]; c. 880 or 903 – c. 950), also Zolta, Zsolt, Solt or Zaltas is mentioned in the Gesta Hungarorum as the third Grand Prince of the Hungarians who succeeded his father Árpád around 907. Although modern historians tend to deny this report on his reign, because other chronicles do not list him among the Hungarian rulers, there is consensus that even if Zoltán never ascended the throne, all monarchs ruling in Hungary from the House of Árpád after around 955 were descended from him.
