Gregory Bicskei (; died 7 September 1303) was a prelate in the Kingdom of Hungary at the turn of the 13th and 14th centuries. He was the elected Archbishop of Esztergom between 1298 and 1303. Supporting the claim of the Capetian House of Anjou, he was a tough opponent of Andrew III of Hungary. He crowned Charles I king with a provisional crown in 1301. He was murdered in Anagni by soldiers whom Philip IV of France had sent to Italy to capture Pope Boniface VIII.
Family
He was born into the gens (clan) Bicske, which possessed landholdings in Pest and Fejér counties. According to the Chronicon Posoniense ("Chronicle of Pressburg"; present-day Bratislava, Slovakia), his father was Botond, which fact was also confirmed by a letter of Pope Benedict XI. Botond was the first known member of the Bicskei (later also known as Szerdahelyi) family. Gregory had two brothers, Peter and John.Engel: Genealógia (Szerdahelyi [Bicskei] family) According to a document dating from 1306, Peter and John were granted permission to levy tolls in the locality of Bicske by Charles I for their military merits. The Bicskeis' genealogical origin was first written by historian Antal Pór. Beforehand, Jesuit scholar György Pray incorrectly considered that Gregory originated from the gens Koppán (or Katapán), while Nándor Knauz also shared this opinion in his work Monumenta ecclesiae Strigoniensis.
Gregory was first mentioned by a contemporary record in September 1274, when a certain noble, John Csapoli, declaring that he has no legitimate heir, handed over a portion of his estate Csabdi as a morning-gift to his wife, Botond's sister. Thereafter she donated the land to her nephews, Peter, John and Gregory. In the same time, they bought the remainder of the estate from John Csapoli on the condition that he and his wife shall be provided with everything necessary until their death. The above contract of sale has been repeated in August–September 1291.
Early career As the youngest of the three brothers, Gregory entered ecclesiastical career. It is possible he is identical with that Gregory, a canon of Székesfehérvár, who represented his king Stephen V in a court of arbitration during a conflict between Philip of Spanheim, Patriarch of Aquileia and the Counts of Gorizia in 1271. He was appointed as a guardian (custos) of the Székesfehérvár Cathedral by provost Theodore Tengerdi sometime between April 1287, the last mention of his predecessor Michael, and February 1289, when Pope Nicholas IV requested trustees from guardian Gregory, cantor Esau and lector Paul to confirm Theodore Tengerdi as provost. Gregory was referred to as guardian in the period from 1287 to 1295. Balázs Kertész argued that Gregory was made guardian sometime between March and June 1287. Beside that, Gregory was also a canon of Esztergom. Benedict Rád, the Bishop of Veszprém nominated Gregory as his legal representative in the lawsuit over the tithe of the three villages of Marót between the diocese and the Dömös Chapter in May 1295. Archbishop Lodomer instructed Gregory (representative of Veszprém), Haab, Bishop of Vác (representative of Sal Hahót, the provost of Dömös) and Emeric, archdeacon of Hont (Lodomer's envoy) to meet in August in Buda. Gregory was present, but due to the absence of Benedict Rád, the trial was postponed to September.
Based on György Bónis, the Hungarian historiography considers that Gregory was elected provost of Székesfehérvár sometime between 24 and 28 April 1295, replacing Theodore Tengerdi. His involvement in the aforementioned lawsuit as guardian makes this assumption unlikely, according to historian Sándor Hunyadi. Gregory Bicskei, with the title of canon of Padua, attended the University of Padua; he was mentioned in this capacity in February 1296 along with Stephen of Gyulafehérvár and Stephanus Catastani. Before that they resided in the royal court of King James II of Aragon for a while, where they acted as envoys of Andrew III, who unsuccessfully tried to establish an alliance against the Angevins. As a result, Hunyadi considered Gregory was elected as provost only after his return to Hungary, sometime in the first half of 1297 (a new guardian named Andronicus also appeared in this dignity in that year). Refusing Hunyadi's argument, Balázs Kertész argued that Gregory became provost-elect in May or June 1295. Following his elevation as provost-elect, Lodomer, the incumbent Archbishop of Esztergom, personally wrote a letter to Pope Boniface VIII in order to confirm Bicskei's election. The document was part of the letter collection of Pietro della Vigna. It is possible that Gregory owned a copy of legal book compiled by the Italian scholar, demonstrating his skill in canon law. As Lodomer reported in the letter, Bicskei, who "was of great origin and had proficiency in canon law", was unable to make a personal journey to Rome because of the "poverty of the church [Székesfehérvár]" and the "intrigues of his relatives". As a result, the archbishop requested Boniface to let Bicskei to maintain his position as an apostolic administrator of Székesfehévár, which was under the direct jurisdiction of the Holy See. His letter clarifies that Gregory was initially belonged to that politically united prelacy, which aimed to strengthen the royal power to put an end to the political anarchy, and even confronted with the Holy See, supporting Andrew and his fight against the provincial lords.
In accordance with the Law of 1290–91, which legitimized a custom right, the office of royal vice-chancellery was permanently held by the provost of Székesfehérvár. Nonetheless, Bicskei replaced Theodore Tengerdi (now as Bishop of Győr) in this dignity only around October 1297. In that capacity, for instance, Bicskei formulated that royal charter on 2 November 1297, in which Andrew III donated Pozsony County to his spouse Queen Agnes, the daughter of Albert I of Germany.
Archbishop-elect Facing Andrew and the Hungarian prelacy Archbishop Lodomer, who was Andrew's staunch ally in his struggles against the provincial lords, died on 2 January 1298. Bicskei was elected as his successor sometime between 18 January and 12 February. During that time, he was considered a loyal partisan of Andrew III, along with the other prelates of the church in Hungary. His candidacy was supported by the monarch too. Bicskei escorted King Andrew and Queen Agnes alongside other dignitaries to Austria on 12 February, where Andrew's only child Elizabeth of Töss was betrothed to Wenceslaus, the son and heir apparent of King Wenceslaus II of Bohemia. Bicskei was last styled as vice-chancellor on 24 February.
His relationship with the monarch and the other prelates had deteriorated permanently in the next six months. He refused to attend that assembly of the prelates, noblemen, Saxons, Székelys, and Cumans, which was summoned by Andrew in Pest in the summer of 1298. Historians agree that Bicskei wanted to reach the papal confirmation of his election as soon as possible, as a result he turned against Andrew and his courtiers, and became a strong advocate of the claim of Charles of Anjou to the Hungarian throne, who enjoyed Pope Boniface's support. With this step, Bicskei intended to disrupt the unity of the Hungarian prelates, who were the strongest pillars of Andrew's reign, but the suffragan bishops remained faithful to the monarch, with the leadership of John Hont-Pázmány, Archbishop of Kalocsa. One of the (23rd) articles of the 1298 diet established a four-member lesser council within the royal council, consisting of two nobles and prelates. Their veto power prevented Bicskei from sabotaging the operation of the royal council, which resulted his total isolation in the state government, despite his nominal leading position in the royal council. Although Bicskei unsuccessfully attempt to shift the prelates from supporting Andrew, but the king' confidence in the Hungarian clergy was shaken due to his activity, as a result he shortly entered into a formal alliance with five influential barons, who stated that they were willing to support him against the Pope and the bishops.
Pope Boniface refused to confirm Bicskei's election on 28 January 1299, but appointed him apostolic administrator of the archdiocese of Esztergom and the provostry of Székesfehérvár. The pope indicated with that if Gregory will represent faithfully the Holy See's interests in Hungary, will receive the final confirmation later, according to historian Attila Zsoldos. Other historians argue the papal rejection of his confirmation prove that Pope Boniface represented a neutral and cautious stance in the struggle between Andrew III and Charles of Anjou. The politically isolated Bicskei, who had hostile relation with the Hungarian clergy, could not be a useful local representative for the Roman Curia. Taking canon law into account, Gábor Thoroczkay emphasizes that Bicskei temporarily administered the archdiocese on behalf of the pope, and, consequently, he was not consecrated, which later became an important consideration in judging the legality of Charles' first coronation. Another aspect that a non-negligible part of the cathedral chapter of Esztergom opposed Bicskei's election in the previous year. Thereafter, Bicskei arbitrarily styled himself "the legate of the Holy See" in his documents. Obtaining the pope's empowerment, he absolved the members of the Kőszegi family from the excommunication on 19 March 1299, which was proclaimed by Lodomer years earlier. Bicskei also forbade the prelates to participate at a new diet which was held around May 1299. In the same time, he convened a synod to Veszprém with his self-declared authority of legate, and obliged the bishops to participate at the event, with the threat of excommunication. However, the prelates ignored the archbishop's order. On 6 July 1299, Emeric, Bishop of Várad was commissioned to send a letter to Pope Boniface to interpret the complaints of Andrew III, Archbishop John and the "entire prelacy and nobility" regarding the behavior of Bicskei and asked Boniface to place them under papal patronage against Bicskei. In the same time Andrew III sent two envoys, Paul, provost of Kalocsa, and Henry Balog, a royal councillor of the inner council, to the court of Esztergom to reconcile with the rebellious archbishop, but, by then, Bicskei resided in Transdanubia under the protection of the Kőszegis. Later he moved to Szentkereszt Castle beyond the Drava river between Koprivnica and Križevci, owned by the oligarch Ivan Kőszegi. As a delegated justice of the pope, Bicskei judged over the lawsuit between Buda and the Dominican nuns of Rabbits' Island regarding local fair duties in December 1299.
Andrew III deprived Bicskei from the perpetual ispánate of Esztergom County shortly before 29 January 1300, when the castellans of the confiscated Esztergom Castle, brothers Jaroslav and Barleus Divék were granted the title of ispán. In the same time, Andrew also sent his envoy, an Italian merchant Petrus de Bonzano from Tarvisio to represent his efforts in Rome. Andrew III wanted to achieve that the pope appoint his confidant Anthony, Bishop of Csanád as Archbishop of Esztergom, instead of Bicskei. Meanwhile, a group of powerful lords—including the Šubići, Kőszegis and Csáks—urged Charles II of Naples to send his grandson, Charles of Anjou, who came to the Kingdom of Hungary upon the invitation of an influential Croatian lord, Paul Šubić, in August 1300. He landed at Split in Dalmatia. Bicskei was among those dignitaries, who welcomed the young pretender. They jointly continued to travel to Zagreb. Pope Boniface refused to appoint Anthony, but still did not confirm the election of Bicskei. The Kőszegis and Matthew Csák, were shortly reconciled with Andrew, preventing Charles' success. Andrew, who had been in poor health for a while, was planning to capture his opponent, but he died in Buda Castle on 14 January 1301.
