Andrew III of Hungary
Andrew III of Hungary made his maternal uncle, Albertino Morosini, Duke of Slavonia, in July 1299, stirring up the Slavonian and Croatian noblemen to revolt. A powerful Croatian baron, Paul Šubić, sent his brother, George, to Italy in early 1300 to convince Charles II of Naples to send his grandson to Hungary to claim the throne in person. The king of Naples accepted the proposal and borrowed 1,300 ounces of gold from Florentine bankers to finance Charles's journey. A Neapolitan knight of French origin, Philip Drugeth, accompanied the twelve-year-old Charles to Hungary. They landed at Split in Dalmatia in August 1300. From Split, Paul Šubić escorted him to Zagreb where Ugrin Csák swore loyalty to Charles. Charles's opponent, Andrew III of Hungary, died on 14 January 1301. Charles hurried to Esztergom where the Archbishop-elect, Gregory Bicskei, crowned him with a provisional crown before 13 May. However, most Hungarians considered Charles's coronation unlawful because customary law required that it should have been performed with the Holy Crown of Hungary in Székesfehérvár.
