[11] The Hungarians sued for peace on Byzantine terms and recognised the empire's control over Bosnia, Dalmatia, Croatia south of the Krka River as well as the Fruška Gora.

[17] In 1203, Serbian Grand Prince Vukan Nemanjić accused Kulin of heresy and lodged an official appeal to the pope.

At Bilino Polje Kulin signed abjuration stating that he was always a faithful Catholic, and saved Banate of Bosnia from outside intervention.

Following the Abjuration of Bilino Polje, Kulin succeeded in keeping the Bosnian Diocese under the Ragusan Archdiocese, thus limiting Hungarian influence.

Kulin's policy was poorly continued since the Ban's death in 1204 by his son and heir, Stjepan Kulinić, who seems to have remained aligned with the Catholic Church.

To make matters worse, the legitimate successor for the Bosnian throne of the Kulinić dynasty, count Sibislav of Usora, son of former Ban Stjepan, started to attack Ninoslav positions, attempting to take Banate for himself.

[citation needed] Pope Gregory IX replaced the heretical Bosnian bishop in 1235 with John of Wildeshausen, then Master General of the Dominican Order and later declared a saint, and confirmed Duke Coloman as the new legitimate Ban of Bosnia.

Ninoslav issued an edict to the Republic of Ragusa on 22 May 1240, stating that he placed it under his protection in case of an attack by Serbian king Stefan Vladislav.

The only significant impact the Bosnian Crusade had was augmenting the anti-Hungarian sentiment among the local population, a major factor in politics that contributed to the Ottoman conquest of Bosnia in 1463[21] and lasted beyond it.

Coloman passed the governorship of Bosnian Banate to Ninoslav distant cousin, Prijezda, who only managed to hold it for two or three years.

Eventually, King Bela IV conquered and pacified Bosnia and succeed in putting Ninoslav 's Catholic cousin Prijezda as the Bosnian Ban.

[23] Prijezda I's realm (founder of Kotromanić dynasty) was significantly smaller than Ninoslav's, the northern regions of Usora and Soli having been detached by the Hungarian crown.

Territory that Ban Prijezda, a loyal Hungarian vassal, controlled was possibly in northern parts of today's Bosnia between rivers Drina and Bosna.

During the end of the 13th and about the first quarter of the 14th century, till the Battle of Bliska Bosnian banate was under the rule of Croatian bans from Šubić family.

[27] By 1326 Ban Stephen II attacked Serbia in a military alliance with the Republic of Ragusa and conquered Zahumlje (or Hum),[28][29] gaining more of Adriatic Sea coast, from mouth of the Neretva to Konavle, with areas significant Orthodox population under Archbishopric of Ohrid and mixed Orthodox and Catholic population in coastal areas and around Ston.

Immediately after the death of Serbian King Stefan Uroš II Milutin in 1321, he had no problem in acquiring his lands of Usora and Soli, which he fully incorporated in 1324.

[citation needed] Throughout his reign in the fourteenth century, Stephen ruled the lands from Sava to the Adriatic and from Cetina to Drina.

[citation needed] In 1346 Zadar finally returned to Venice, and the Hungarian King, seeing that he had lost the war, made peace in 1348.

Following her return, Jelena held an assembly (stanak) in Mile, with mother and son confirming the possessions and privileges of the noblemen of "all of Bosnia, Donji Kraji, Zagorje, and the Hum land".

[36] In Usora, the Srebrenik Fortress held out against a "massive attack" by the royal army,[36] which suffered the embarrassment of losing the King's seal.

[36] Tvrtko returned to Bosnia in March and reestablished control over a part of the country by the end of the month, including the areas of Donji Kraji, Rama (where he then resided), Hum, and Usora.

[36][43] Ragusan officials made an effort to procure peace between the feuding brothers,[43] and in 1368, Vuk asked Pope Urban V to intervene with King Louis I on his behalf.

[43] The death of Dušan the Mighty and the accession of his son Uroš the Weak, in December 1355, was soon followed by the breakup of the once-powerful and threatening Serbian Empire.

By the mid-14th century, Bosnian banate reached its peak under young ban Tvrtko Kotromanić who came into power in 1353, and had himself crowned on 26 October 1377.

[47] Access to Via Narenta was crucial for Bosnian economy, which was possible only after ban Stephen II managed to take control of the trading route during his conquests of Hum.

[48] Lying in-between, the mountainous Bosnia was nominally under Rome,[48] but Catholicism never became firmly established due to a weak church organization[48] and poor communications.
