Franco (bishop)

Franco (Frank) was a Hungarian prelate in the 11th century, who was a councilor of Solomon, King of Hungary in the early 1070s. Which bishopric he administered is uncertain.

Identification
Two foreign sources, the Chronicon Sancti Huberti Andaginensis and the Vita Theoderici Abbatis Andaginensis, both from Liège refer to a certain "Franco Bellagradensis pontifex" and "Franco episcopus Bellagradensis", respectively, under the year 1081. Based on this, Croatian historian Franjo Rački considered that Franco functioned as a bishop of Biograd (in Dalmatia). Historian Gyula Pauler identified "Bellagradensis" with Gyulafehérvár (present-day Alba Iulia, Romania), accordingly Franco could have been a bishop of Transylvania. His theory was accepted by György Györffy and Gyula Kristó too. In contrast, Péter Váczy identified Franco's (titular) episcopal see with Belgrade (today Serbia's capital), where a Greek-ryte metropolitanate located at the turn of the 11–12th centuries. There is another source, the death register (obitury) of the Saint Lambert's Cathedral, also in Liège, which commemorates a certain deceased Franco, the bishop of Veszprém ("commemoratio Franconis episcopi apud Vesperem que est civitas Hungariae"), who died in 1081. Gábor Thoroczkay accepted this data, arguing that Székesfehérvár, or "Alba Regia", located in the diocese too, where the suffragan also possessed a palace. Tibor Szőcs considered the identification of "Bellagradensis" with Biograd, where a diocese existed from 1059 to 1125 until the city was conquered and demolished by the Republic of Venice. Pál Engel and László Koszta also considered that Franco was perhaps a bishop of Veszprém sometime around 1071–1081.

György Székely argued Franco was of Walloon origin. Based on the aforementioned death register, he considered that he served as bishop of Veszprém. Székely identified his person with the Polish prelate Franko ("episcopus Poloniensis"), who was a councilor of Władysław I Herman in the 1080s, according to the Gesta principum Polonorum. Székely identified "Bellagradensis" with Belgard, Pomerania (today Białogard, Poland), where he functioned as a missionary bishop (thus this Walloon-born prelate moved from Hungary to Poland sometime in the late 1070s). He visited the Abbey of Saint-Hubert in this capacity in 1081 during the consecration of the new altar dedicated to Saint Giles, in the companion of Henry of Verdun, the bishop of Liège. Later, Franco also visited the Abbey of Saint-Gilles in 1084. Upon his plausible invitation, Benedictines from Liège settled in Lubin.

Elemér Mályusz rejected Székely's reconstruction, because there is no source that Białogard was ever an episcopal seat. Dániel Bagi argued there is no identification with the Polish prelate Franko, who was bishop of Poznań, according to the Polish historiography (e.g. Władysław Abraham and Roman Grodecki). Bagi argued the sources from Liège refer to the Polish prelate only. In addition, Białogard was conquered by only Bolesław III Wrymouth in 1107. Judit Csákó, however, did not reject identification with the Polish prelate.
