Accordingly, Stephen had established a mass-endowment for his late father's spiritual salvation and financed its operation from the income of Urkuta, while its lawfulness was denied by Györk and his patron Benedict, Archbishop of Kalocsa.

[9] Stephen and Vincent also had a younger brother Peter, who had two sons Orbász II, provost of Pozsega (today Požega, Croatia) then chancellor for Dowager Queen Elizabeth the Cuman.

[2] It is possible that Stephen also had another (unidentified) brother, who might be was the father of his two nephews, Carulus (canon of Veszprém, then Esztergom) and John (dean of Győr, Zala, then chaplain for Cardinal Báncsa).

[11] Historian Dániel Bácsatyai considered this brother is identical with that "Denis of Hungary", who escorted Queen Violant to the Kingdom of Aragon in 1235, where he became progenitor of the influential Dionisii noble family.

[15][16] Still in 1238, he appears in the same capacity in a charter of Palatine Denis Tomaj, when they jointly judged over a possession lawsuit between Bartholomew, Bishop of Veszprém and the Pannonhalma Abbey.

He was a member of an ad hoc council summoned by Denis Tomaj to judge in the case of Sala church estate which had several jurisdictional conflicts over the years.

Two royal documents suggest that Báncsa presumably still held the court office during the Mongol invasion of Hungary in 1241, but their credibility is highly questionable.

[18] After the death of Robert, Archbishop of Esztergom on 1 November 1239, Matthias Rátót, Bishop of Vác was elected as his successor in the same month, which was confirmed by Pope Gregory IX in March 1240.

[24] Pope Innocent IV, elected on 25 June 1243, confirmed Báncsa's appointment as Archbishop of Esztergom, being transferred from the Diocese of Vác with the permission of the Roman Curia, granted on 7 July 1243.

[32] When Béla confirmed the privileges of the hospes in Beregszász (today Berehove, Ukraine) in December 1247, the king assigned the jurisdiction of Esztergom to the Saxon community.

At Christmas 1248, Pope Innocent IV dispensed annually forty-day plenary indulgence to the Esztergom Cathedral due to the intercession of Báncsa, which further increased his influence.

Four years later he is said to have been admonished in a vision to gather into community the other hermits living in the vicinity, for whom he built a monastery and church the ruins of which are near the village of Pilisszentlélek (today a part of Esztergom).

Eusebius received the approbation of Bartholomew, Bishop of Pécs, for the new Order, but the publication of the decrees of the Fourth Lateran Council at this time necessitated a journey to Rome to secure final authorization by the Holy See.

In fact, as they emphasized, the persecution of the Church by the Emperor Frederick overshadowed all other threats in Rome, including the danger of Mongol invasions against Europe.

Báncsa's predecessor, Giacomo di Pecorari (otherwise a papal legate to Hungary in the 1230s) died on 25 June 1244, just one month after the first creation process of the cardinals during Innocent's papacy.

In addition to his ethnicity, Kiss assumes that his affinity to the hermit movements and his personal relationship with Innocent (born Sinibaldo Fieschi, formerly a clerk of Pope Gregory IX) could be reasons why he was chosen to become cardinal.

[44] Three prelates, Stephen Báncsa, Ottobuono de' Fieschi (future Pope Adrian V) and Giacomo da Castell'Arquato were created cardinals in the same time.

Even so, upon his personal request, he continued to serve as Administrator of the Archdiocese of Esztergom (1252–1254),[46] usurping its income of tithe from Csallóköz (today Žitný ostrov, Slovakia).

[49] According to his own document, Báncsa became ill, due to his being unaccustomed to the climate, among other reasons,[50] and he therefore petitioned Pope Innocent IV to allow him to return to Hungary.

[51] Historians László Koszta and Tibor Almási considered that Báncsa wanted to return to Hungary because of financial difficulties, beside climatic inconveniences.

The Pope died in Naples on 7 December, five days after the disastrous battle of Foggia in which the papal army was soundly defeated and lost over 4,000 men.

Alongside Jacobus de Porta, Riccardo Annibaldi and Giovanni Gaetano Orsini (future Pope Nicholas III), Stephen Báncsa represented a neutral stance.

[63] In the same year, Báncsa was a member of that papal committee, which investigated the work of Franciscan friar Gerardo of Borgo San Donnino, who, in 1250, published his book entitled Introductorium in Evangelium Aeternum, which represented Joachimite idea.

Béla protested against the pope's decision, referring to Timothy's "incapability to become a royal advisor" (possibly because of his close relationship with the cardinal, who had several conflicts with the king prior that).

Béla was angered by the fact too that Pope Urban allowed to Cardinal Báncsa to be free to distribute Timothy's benefices in Hungary among his nephews and other relatives.

His family became staunch supporters of Duke Stephen, who adopted the title of junior king in 1262 and ruled the eastern parts of the kingdom de facto independently.

[78] On February 26, at Perugia, only three weeks after the Election and three days after the Coronation, he and fifteen other cardinals subscribed a bull, Olim regno, notifying Henry of England and his son Edmund that they were not the true possessors of the Kingdom of Sicily.

[84] Due to his advanced age, Báncsa gradually retired from papal governance and public life after 1268, staying away from the political intrigues in the conclave.

[85] Based on a record in the last pages of a manuscript of his own, a copy of Peter Lombard's Libri Quattuor Sententiarum, preserved by the Bibliothèque nationale de France, Stephen Báncsa was feverish and fell ill in the first day of July 1270.

The two executioners of his last will were canonist Henry of Segusio and Giovanni Gaetano Orsini (elected Pope Nicholas III in 1277), which reflected his social appreciation in the Curia.
