Michael from the kindred Bő, was a Hungarian prelate at the turn of the 13th and 14th centuries, who served as Bishop of Zagreb from 1296 to 1303, then Archbishop of Esztergom from 1303 until his death.
Early career
Michael was born into the Ders branch of the gens Bő, which originated from Somogy County, and was one of the ancient ethnic Hungarian kindreds which had participated in the Hungarian conquest of the Carpathian Basin in late 9th century. His younger brother was Peter the Toothed. Through their unidentified paternal aunt, Michael and Peter were related to the gens Monoszló and its influential contemporary members, brothers Egyed, Gregory and Peter. As contemporary sources frequently referred to him with the prefix "magister", Michael studied canon law. In 1270, he was a notary in the court of King Stephen V. It is also possible that he served as archdeacon of Ózd since 1277. Due to the influence of his cousin, Peter Monoszló, Bishop of Transylvania, Michael was elected Grand Provost by the Transylvanian Chapter in 1287, holding the position until 1296. Meanwhile, his brother Peter Bő became Count of the Székelys around 1294. In December 1294, Egyed Monoszló donated three villages of the Atyina lordship to the Bő brothers, entrusting the Pécs Chapter to contribute his instruction. The land donation was confirmed by Andrew III on 9 January 1295. Egyed Monoszló made his first will and testament in 1298, when formally adopted his maternal relatives Michael and Peter. Egyed donated Darnóc Castle to them, however both Michael and Peter predeceased him.
Prelate
After the death of his predecessor John on 13 October 1295, who supported the Angevins' claim to the Hungarian and Croatian thrones, Michael Bő, a confidant of King Andrew III was elected Bishop of Zagreb. He first appeared in that capacity in 1296. His election was confirmed by Pope Boniface VIII on 20 January 1297. In the same time, Michael became chancellor in the court of Andrew's uncle Albertino Morosini, Duke of Slavonia, in addition to his titles of ispán of Garics and Gerzence lordships, held both from 1297 until 1303. However, practically, those territories were occupied by the powerful Kőszegi family since the 1280s, neglecting the diocese's legal claims. Albertino Morosini and Michael Bő represented the royal power in the province of Slavonia against the increasingly powerful oligarchs and the pro-Angevin baronial groups. The new Bishop removed and expelled his predecessor's confidants from the town and the chapter. Michael concluded a contract with the Babonići to fought against the Kőszegis, whose troops even plundered and devastated the territory of the Diocese of Zagreb, while looted its treasures. Michael led numerous royal campaigns against the Kőszegis' territory. Its overlord Henry Kőszegi concluded a peace with the Bishop by the end of 1297 and handed over the forts of Gerzence and Garics to the diocese, which suffered from the endless warfare. Under such conditions, Michael financially supported the Chapter of Čazma from his own wealth. After the Diet of 1298, he remained in the royal court and never visited his diocese or the Croatian province again. Michael's seal from 1299 preserved the first art depiction of the Zagreb Cathedral. Andrew III died on 14 January 1301. Following that Michael became one of the first partisans of Charles of Anjou beside Archbishop-elect Gregory Bicskei, while majority of the prelates supported the claims of the Bohemian prince Wenceslaus. As a skilled notary and canonist, he help the diplomatic work of papal legateNiccolo Boccasini, who tried to persuade the secular barons to support Charles' claim against the other pretenders. In September 1302, Michael was present, when Charles' general Stephen Csák laid siege to Buda, the capital of Wenceslaus' realm, but Ivan Kőszegi relieved the siege. Pope Boniface, who regarded Hungary as a fief of the Holy See declared Charles the lawful king of Hungary on 31 May 1303. The papal bull was annunciated in Hungary by Michael Bő and Stephen, the new Archbishop of Kalocsa. His ally, Archbishop-elect Gregory Bicskei was murdered in Anagni on 7 September 1303 by soldiers whom Philip IV of France had sent to Italy to capture Pope Boniface, who also died in the next month. Michael's former colleague Niccolo Boccasini was elected as Pope Benedict XI. On 4 November 1303, he appointed Michael as Archbishop of Esztergom, while characterizing his friend as "noble, scholar, fine and diligent". On 21 March 1304, the Pope informed Benedict Rád, Bishop of Veszprém that he had sent the pallium to Michael, after the receipt of his oath of loyalty. On 24 August 1304, Michael styled himself as "Archbishop appointed from the God's grace". Only a few information has been preserved during his brief primacy; on 4 February he lifted clergyman Bede from the excommunication at the Pope's instruction, while excommunicated Nicholas, son of Felician, a canon of Esztergom on 15 May, who unlawfully usurped the goods of the Szepes Provostry. In the summer of 1304, the Bohemian army invaded Upper Hungary and encamped at Párkány. There Wenceslaus II of Bohemia called upon Michael to crown his namesake son as King of Hungary, but the Archbishop refused the threat. Following that the Bohemian troops stormed Esztergom and looted its treasury, in addition to the destruction of diplomas and holy relics. Michael fled his archbishopric seat for Pressburg, where he died soon. On 1 November 1304, Theophilus, Provost of Esztergom already referred to him as a deceased person. Michael was buried in the St. Martin's Cathedral.
