Radivoj of Bosnia

Radivoj of Bosnia (; died in late May or early June 1463) 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. Background Radivoj was the older of the two illegitimate sons of King Ostoja. He was most likely born before 1410, during Ostoja's marriage to Kujava Radinović, the mother of the King's only legitimate son, Stephen Ostojić. Like his younger brother Thomas, Radivoj was a doubly adulterine child, as his father confessed to the pope that their mother too had a living husband at the time of their births. The surname Kristić (or Krstić or Hrstić), which was often appended to his name, was most likely derived from his mother's family name. Upon Ostoja's death in September 1418, Radivoj's older half-brother Stephen ascended the throne, but was deposed by their father's nephew and rival Tvrtko II in 1421, dying soon afterwards. Anti-king
