Prijezda was originally a Roman Catholic Christian, but he converted to Bogomilism later on. According to the Pope's letter to BanMatej Ninoslav, he converted back to Catholicism during Matej's reign. As he could not be trusted because of his previous conversion, he was forced to send his son as a guarantee to the Dominican Order. Ban Matej Ninoslav had to beg even to Rome itself for the release of Prijezda's son, Prijezda II, guaranteeing that they are none other than faithful Catholics - but the pleas reached deaf ears.
During the Crusades in Bosnia against Matej Ninoslav Herzeg Coloman commanding the ChristianArmies conquered most of Bosnia and temporarily pushed Matej and his forces. He gave the title of Bosnian Ban to Prijezda, who was Ninoslav's closest living relative. Prijezda ruled for only two years, because Matej managed to restore control over most of Bosnia after the Hungarian defeat in the face of the Tartars. As Prijezda was in mortal danger, he fled to Hungary.
Ban
After the death of Matej Ninoslav in 1250, the question of power over Bosnia was initiated. Ninoslav's sons fought valiantly to keep Bosnia independent, but eventually KingBéla IV of Hungary martially subjected Bosnia and made Prijezda its Ban, who vouched to rule in Hungary's name. After he became Ban, Prijezda started a campaign to exterminate the Bosnian Church's heresy in Bosnia. Due to his ruthless fight against the Bogumils, the Pope ordered the Dominicans to return him his son as it appeared that Prijezda became a pious Catholic. On 11 November 1253 Hungarian King Bela wrote how he fiercely fought against the Bosnian heretics with his armies. After that, King Bela partitioned the Bosnian banate in a way that Prijezda was given Bosnia proper, the area between the valleys of the rivers of Vrbas and Bosna, as his hereditary demesne. Usora and Solion the other hand were made separate banates ruled by Bans named by the King - Rostislav, Béla, Michael - later subjected to the Banate of Macsó, which had been raised to a Dukedom. Eventually, Bosnia itself was subjected to the Duchy of Macsó. Because of his heroic fights, Prijezda received the title "Fidelis Noster" from the Hungarian King, as well as several lands outside Bosnia, around Gornji Miholjac. King Bela IV of Hungary attacked the Serb Kingdom of Rascia of King Stefan Uroš I and conquered Zahumlje in 1254 which it gave to Prijezda's Bosnia, but the eventual peace between Hungary and the Serbs returned it to Rascia. In 1255 the Hungarian King granted new lands to the Bosnian Ban in Slavonia. Prijezda had to dispatch Bosnian forces in 1260 to fight in the Hungarian Army against the Bohemian King. In 1270, King Bela IV died. He was succeeded by his son Stephen V. The powerful Duke of Macsó was killed a war in 1272. The same year King Stephen V died. The Hungarian throne was succeeded by his son Ladislaus IV. He was too young to rule, so his Cuman mother Elizabeth acted as regent. During these changing times for the power in Hungary Prijezda's power dropped severely. Not only did several Hungarian nobles, including Ugrin of Severin, Hungary's treasure-holder included Bosnia in their titles, but a certain Bosnian nobleman Stephen appeared in Bosnia with high influence and prestige; greatly surpassing that of Prijezda. In 1284, Prijezda arranged a marriage between the Serbian Princess Jelisaveta, daughter of the King ofSyrmia, Stefan Dragutin, and his son Stephen I Kotromanić in an attempt to forge an ever-lasting alliance with Dragutin. Prijezda was forced to withdraw from the throne in 1287 due to his old age. He spent his last hours on his estate in Zemljenik.
