The Bosnian Crusade was fought against unspecified heretics from 1235 to 1241 and was essentially a Hungarian war of conquest against the Banate of Bosnia that was sanctioned as a crusade. Led by a Hungarian prince, Coloman, the crusaders succeeded in conquering only peripheral parts of the country. They were followed by Dominicans, who erected a cathedral and put heretics to death by burning.

The crusade came to an abrupt end when Hungary itself was invaded by the Mongols during the Mongol invasion of Europe. The crusaders were forced to withdraw and to engage their own invaders, with most of them perishing including Coloman. Later popes called for more crusades against Bosnia, but none ever took place. The failed crusade led to mistrust and hatred for Hungarians among the Bosnians that lasted for centuries.

Background

Several crusades were called against Bosnia, a country that had long been deemed infested with heresy by both the rest of Catholic Europe and Orthodox Europe. The first crusade was averted in April 1203, when the Bosnians under Ban Kulin promised to practice Christianity according to the Roman Catholic rite and recognized the spiritual supremacy of the Pope. Kulin also reaffirmed the secular supremacy of the kings of Hungary over Bosnia. In effect, however, the independence of the Bosnian Church and the Banate of Bosnia continued to grow.^[1]

At the height of the Albigensian Crusade against the French Cathars in the 1220s, a rumour broke out that a "Cathar antipope", called Nicetas, resided in Bosnia. It has never been clear whether Nicetas existed, but neighbouring Hungary took advantage of the rumour to reclaim suzerainty over Bosnia, which had been growing increasingly independent.^[2] The Bosnians were accused of being sympathetic to Bogomilism, a Christian sect that was closely related to Catharism and likewise dualist.^[3] In 1221, the concern finally prompted Pope Honorius III to preach a crusade against Bosnia.^[2] He repeated this in 1225, but internal problems prevented the Hungarians from answering his call.^[1]

Honorius III's successor, Pope Gregory IX, accused the Catholic bishop of Bosnia himself of sheltering heretics, in addition to illiteracy, simony, ignorance of the baptismal formula and failure to celebrate Mass and the sacraments. He was duly deposed in 1233 and replaced with a German Dominican prelate, John of Wildeshausen, the first non-Bosnian bishop of Bosnia. The same year, Ban Matthew Ninoslav abandoned an unspecified heresy, but that did not satisfy Gregory.^[1]

Conflict

In 1234, Pope Gregory IX issued another call for crusade, and this time, Hungary readily responded. It is possible that the Bosnians had failed to align their church with Rome, but the crusade actually served as a perfect excuse for the Hungarians to expand their authority.^[1] Gregory promised indulgences to prospective crusaders and entrusted Coloman, the younger son of Andrew II and brother of Béla IV, with executing the military action.^[3]^[4] Coloman and his followers were put under protection of the Holy See.^[4] Neither the enemies nor the targeted region were precisely named in the letters the Pope sent to Coloman and the Bishop of Bosnia. He referred to "Slavonia" and mentioned "lands of Bosnia" only in the letter to the Bishop. It is generally understood that by "Slavonia", he meant Bosnia and its surroundings, Slavic lands or even to actual Slavonia. The fact that the Bishop of Bosnia was informed, however, makes it clear that Bosnia itself was targeted. The action seems to have been taken against Bosnians in general as only "heretics" are mentioned; it is implied in one source that the crusade was directed against dualists.^[4]

Active fighting began in 1235, but the Hungarian Army reached Bosnia proper only three years later. The delay may have been caused by the popular resistance in the north of the country, Soli, where the mountainous terrain helped "many heretics" fight the crusaders.^[1]^[4] In August 1236, Pope Gregory ordered the crusaders not to pester Matthew Ninoslav's relative Sibislav, the knez of Usora, or his mother, who were both "good Catholics" among heretical nobles, "lilies among thorns".^[4] Vrhbosna apparently fell in 1238, when a cathedral was constructed by Dominicans, who followed the crusaders. The crusaders failed to conquer all of Bosnia, however, as Matthew Ninoslav continued to act as ban throughout the conflict in the central parts of his realm, where Dominicans never set foot. The order took control of the Catholic Church in Bosnia, which was now led by a new bishop, the Hungarian Ponsa. The Dominicans recorded that some heretics were burned at the stake but do not appear to have discovered anything about the nature of the heresy. The crusaders then either reached as far south as Zachlumia or intended to do so.^[1]

Then, in 1241, the Mongol invasion of Europe saved Bosnia. The Mongols under Batu Khan, having subdued and devastated Kievan Rus', invaded Hungary. The Hungarian troops were forced to withdraw from Bosnia and face their own invaders. Much of their army was wiped out in the Battle of Mohi. Coloman, the commander of the crusaders, was among those killed. The Mongols plundered Dalmatia, Croatia, Zeta, Serbia and Bulgaria. Their attack proved disastrous for all of the Balkans but Bosnia. The crusaders were annihilated and never returned.^[1] Bosnia retook the occupied territories and maintained its level of independence following what turned out to be a Hungarian war of conquest that was sanctioned as a crusade.^[5]

Aftermath and legacy

The threat of new religious persecution in Bosnia reappeared within a few years of the war. Pope Innocent IV began urging the Hungarians to undertake another crusade in late 1246 and 1247, and they appeared willing. Matthew Ninoslav argued that he had associated with heretics only to defend Bosnia from Hungarian invaders.^[1] He appears to have convinced Innocent,^[1] who suspended the crusade in March 1248.^[4]

A crusade against Bosnia was preached again in 1337–1938 and 1367 by Popes Benedict XII and Urban V, respectively, but in drastically different political circumstances. Hungary was ruled by a new dynasty, the Capetian Angevins, who supported the Kotromanić rulers of Bosnia.^[1] King Charles Robert once declared that any Hungarian who attacked Bosnia, ruled by his friend Stephen II, would be regarded as a traitor.^[4]

The only significant impact of the Bosnian Crusade was augmenting the anti-Hungarian sentiment among the Bosnians that greatly contributed to the Ottoman conquest of Bosnia in 1463^[1] and lasted afterward.^[4]

Catharism was a Christian quasi-dualist or pseudo-Gnostic movement which thrived in Southern Europe, particularly in northern Italy and southern France, between the 12th and 14th centuries. Denounced as a heretical sect by the Catholic Church, its followers were attacked first by the Albigensian Crusade and later by the Medieval Inquisition, which eradicated the sect by 1350. Many thousands were slaughtered, hanged, or burnt at the stake, sometimes without regard for age or sex.

The Medieval Inquisition was a series of Inquisitions from around 1184, including the Episcopal Inquisition (1184–1230s) and later the Papal Inquisition (1230s). The Medieval Inquisition was established in response to movements considered apostate or heretical to Roman Catholicism, in particular Catharism and Waldensians in Southern France and Northern Italy. These were the first movements of many inquisitions that would follow.

The Albigensian Crusade, also known as the Cathar Crusade (1209–1229), was a military and ideological campaign initiated by Pope Innocent III to eliminate Catharism in Languedoc, what is now southern France. The Crusade was prosecuted primarily by the French crown and promptly took on a political aspect. It resulted in the significant reduction of practicing Cathars and a realignment of the County of Toulouse with the French crown. The distinct regional culture of Languedoc was also diminished.

Bogomilism was a Christian neo-Gnostic, dualist sect founded in the First Bulgarian Empire by the priest Bogomil during the reign of Tsar Peter I in the 10th century. It most probably arose in the region of Kutmichevitsa, today part of the region of Macedonia.

The Bosnian Church was a schismatic Christian church in medieval Bosnia and Herzegovina that was independent from and considered heretical by both the Catholic and the Eastern Orthodox churches.

The Kingdom of Croatia entered a personal union with the Kingdom of Hungary in 1102, after a period of rule of kings from the Trpimirović and Svetoslavić dynasties and a succession crisis following the death of king Demetrius Zvonimir. With the coronation of King Coloman of Hungary as "King of Croatia and Dalmatia" in 1102 in Biograd, the realm passed to the Árpád dynasty until 1301, when the (male) line of the dynasty died out. Then, kings from the Capetian House of Anjou, who were also cognatic descendants of the Árpád kings, ruled the kingdoms. Later centuries were characterized by conflicts with the Mongols, who sacked Zagreb in 1242, competition with Venice for control over Dalmatian coastal cities, and internal warfare among Croatian nobility. Various individuals emerged during the period, such as Paul I Šubić of Bribir, who was representing the most powerful Croatian dynasty at the time, the Šubić noble family. These powerful individuals were on occasion able to de facto secure great deal of independence for their fiefdoms. The Ottoman incursion into Europe in the 16th century significantly reduced Croatian territories and left the country weak and divided. After the death of Louis II in 1526 during the Battle of Mohács and a brief period of dynastic dispute, both crowns passed to the Austrian House of Habsburg, and the realms became part of the Habsburg monarchy.

Kulin was the Ban of Bosnia from 1180 to 1204, first as a vassal of the Byzantine Empire and then of the Kingdom of Hungary, although his state was de facto independent. He was one of Bosnia's most prominent and notable historic rulers and had a great effect on the development of early Bosnian history. One of his most noteworthy diplomatic achievements is widely considered to have been the signing of the Charter of Ban Kulin, which encouraged trade and established peaceful relations between Dubrovnik and his realm of Bosnia. His son, Stephen Kulinić succeeded him as Bosnian Ban. Kulin founded the House of Kulinić.

Béla IV was King of Hungary and Croatia between 1235 and 1270, and Duke of Styria from 1254 to 1258. As the oldest son of King Andrew II, he was crowned upon the initiative of a group of influential noblemen in his father's lifetime in 1214. His father, who strongly opposed Béla's coronation, refused to give him a province to rule until 1220. In this year, Béla was appointed Duke of Slavonia, also with jurisdiction in Croatia and Dalmatia. Around the same time, Béla married Maria, a daughter of Theodore I Laskaris, Emperor of Nicaea. From 1226, he governed Transylvania as duke. He supported Christian missions among the pagan Cumans who dwelled in the plains to the east of his province. Some Cuman chieftains acknowledged his suzerainty and he adopted the title of King of Cumania in 1233. King Andrew died on 21 September 1235 and Béla succeeded him. He attempted to restore royal authority, which had diminished under his father. For this purpose, he revised his predecessors' land grants and reclaimed former royal estates, causing discontent among the noblemen and the prelates.

Matej Ninoslav was the Ban of Bosnia in the period of 1232–50. Most of Bosnia was under the Kingdom of Hungary from 1235 to 1241. Ninoslav was also a Prince of Split in 1242–1244 during the local civil war. Ninoslav established control of most of Bosnia after the Hungarian withdrawal. Ninoslav continually defended Bosnia during the Bosnian Crusade that persecuted its heretic population. He was succeeded by his cousin, Ban Prijezda, in 1254.

Stephen or StjepanBan of Bosnia, was the third Bosnian ban who ruled the banate of Bosnia recorded by name in written sources. He was in power sometime between 1204 and 1232. His rule was not popular, due to his Catholicism and allegiance to the Kingdom of Hungary. He was the last ruler of the House of Kulinić.

Prijezda I (Serbian Cyrillic: Пријезда I; pronounced[prǐjezda] was a Bosnian Ban as a vassal of the Hungarian Kingdom, reigning 1250–1287. He was probably the founder of the House of Kotromanić.

Coloman of Galicia was the ruler—from 1214 prince, and from 1215 or 1216 to 1221, the king—of Galicia, and the duke of Slavonia from 1226 to his death. He was the second son of Andrew II of Hungary and Gertrude of Merania. His father and Leszek the White, Duke of Poland, concluded an agreement about the marriage of Coloman and Leszek's daughter, Salomea, and the division of Galicia, allotting its western regions to Leszek, the remaining lands to Coloman. The Hungarian and Polish armies occupied the principality in late 1214. Andrew II appointed a Hungarian nobleman, Benedict the Bald, to administer it on Coloman's behalf. Coloman was crowned the first king of Galicia with the pope's authorization in early 1216.

Ugrin from the kindred Csák was a Hungarian prelate and military leader in the first half of the 13th century, who served as Archbishop of Kalocsa from 1219 until his death at the Battle of Mohi on 11 April 1241. He was also chancellor of the royal court from 1217 to 1219 and from 1230 to 1235.

Ponsa or Pousa was a Hungarian-born Dominican friar who served as Bishop of Bosnia from 1238 to 1270. He was appointed by Pope Gregory IX in an effort to combat the autonomous Bosnian Church, but found no support in Bosnia. He fled the country in the 1240s, never to return.

The Eastern Roman (Byzantine) imperial church headed by Constantinople continued to assert its universal authority. By the 13th century this assertion was becoming increasingly irrelevant as the Eastern Roman Empire shrank and the Ottoman Turks took over most of what was left of the Byzantine Empire. The other Eastern European churches in communion with Constantinople were not part of its empire and were increasingly acting independently, achieving autocephalous status and only nominally acknowledging Constantinople's standing in the Church hierarchy. In Western Europe the Holy Roman Empire fragmented making it less of an empire as well.

The Banate of Bosnia, or Bosnian Banate, was a medieval state based in what is today Bosnia and Herzegovina. Although Hungarian kings viewed Bosnia as part of Hungarian Crown Lands, the Banate of Bosnia was a de facto independent state for most of its existence. It was founded in the mid-12th century and existed until 1377 with interruptions under the Šubić family between 1299 and 1324. In 1377, it was elevated to a kingdom. The greater part of its history was marked by a religiopolitical controversy revolving around the native Christian Bosnian Church condemned as heretical by the dominant Chalcedonian Christian churches, namely the Catholic and Eastern Orthodox churches, with the Catholic Church being particularly antagonistic and persecuting its members through the Hungarians.

Vox in Rama is a decretal sent by Pope Gregory IX in June 1233 condemning the heresy of Luciferianism said to be rife in Germany, and authorizing the preaching of a crusade against it. Copies of the letter were sent to Emperor Frederick II, King Henry (VII) of Germany, Archbishop Siegfried III of Mainz, his suffragans, Bishop Conrad II of Hildesheim and the preacher Konrad von Marburg. The copies are dated to 11, 13 and 14 June.

Anti-Hungarian sentiment is dislike, distrust, discrimination, or xenophobia directed against the Hungarians. It can involve hatred, grievance, distrust, intimidation, fear, and hostility towards the Hungarian people, language and culture.

Rastudije, also Aristodius, was a bishop of the Bosnian Church, or a djed, as the bishops as a leader of the Bosnian Christians has been originally titled. He was declared a heretic by both the Orthodox and Catholic churches.

It was signed by seven priors of the Bosnian Church, on 8 April 1203 at Bilino Polje field, near today town of Zenica, in Bosnia and Herzegovina. The same document was brought to Buda, in 30 April by Giovanni da Casamari, Ban Kulin and two abbots, where it was examined by Emeric, King of Hungary, and the high clergy
