context_page_description: Radivoj of Bosnia was anti-king of Bosnia from 1432 until 1435, when he lost all control over the kingdom but did not relinquish the title, and again from 1443 until 1446, when he abandoned his claim. He was recognized as king by the Ottoman Empire and the Despotate of Serbia, as well as by the Bosnian noble houses of Kosača and Pavlović, but never by the West. Radivoj is thus seldom included in the list of rulers of Bosnia.
context_section_description: In June 1449, Radivoj married Catherine, the second of the three daughters of the Hungarian nobleman Nicholas of Velika, who had no sons. An inheritance pact was signed between the men on 19 June, establishing that the marriage would be contracted according to Roman Catholic rite and that the couple would inherit a third of Nicholas' Slavonian and Hungarian possessions after he and his wife Margaret die. Radivoj, in turn, gave half of his estates in Bosnia and Slavonia to his parents-in-law. Catherine and Radivoj had three sons; Tvrtko and George, who are mentioned in 1455, and Matthias, probably the youngest.
  Radivoj spent the remainder of Thomas' reign peacefully and aiding his brother when necessary. In 1458, he took part in the negotiations with the Hungarian king Matthias Corvinus and the Serbian despoina Helena Palaiologina regarding the marriage of his nephew Stephen Tomašević and Helena's daughter Helena. King Thomas' sent Radivoj to Hungary as an envoy in October. In January the following year, Radivoj accompanied his nephew to the session of the Diet of Hungary in Buda, and two months later to Smederevo, where Stephen married Helena and became the new despot. In June, however, the Ottomans army attacked Serbia and approached the Smederevo Fortress. No attempt to defend it was made, and Radivoj negotiated surrender and safe conduct of the royal family. The King of Hungary accused Radivoj and Thomas of betrayal and selling the fortress to the Ottomans, "damaging the Christendom", and confiscated the estates Radivoj held in his kingdoms. Matthias circulated the allegation throughout Europe, while Thomas made great effort to deny it. He sent emissaries to Mantua, where they were received by Pope Pius II on 10 July before Matthias's accusation reached him. Radivoj was probably one of the envoys, as the Pope took the opportunity to address a request he made regarding private worship.
