The judge of the Cumans ( or kunbíró; ) was a short-lived legal office, then an ex officio title in the Hungarian royal court, existed since the second half of the 13th century. In 1270, the Palatine of Hungary assumed the dignity and became part of its title to merge the two positions for centuries, during which time Cuman settlers were concentrated into Kunság region.
History
Origins
The position most possibly evolved with the resettlement of the Cuman tribes following the Mongol invasion of Hungary in 1242. In the introductory of the so-called second Cuman law of 1279, King Ladislaus IV ("the Cuman") referred to his grandfather King Béla IV, who placed Cumans under the direct jurisdiction of the Palatine, accordingly. Nora Berend, among others, questioned the authenticity of the document and called an "18th century forgery" which served the purpose of historical legitimacy to the restoration (redemptio) of the autonomous Jassic-Cuman district by Maria Theresa in 1745. In contrast, historians Attila Zsoldos and Tibor Szőcs considered the text is authentic and claimed the Palatine received that authority already during the Cumans' first entry into Hungary in 1239, in analogy to the status of the dignity of Count of the Pechenegs. Szőcs argues Denis Tomaj unusually held ispánates in Eastern Hungary beside his position of Palatine, which laid near to the Cuman tribes' lands, thus he could be the first office-holder who became judge of the Cumans. Contrary to Denis Tomaj, later Palatines after the Battle of Mohi (11 April 1241), for instance Ladislaus Kán, Denis Türje, Roland I Rátót and Henry Kőszegi originated from Transdanubian kindreds, causing the decline and marginalization of the dignity of judge of the Cumans, in addition to the emerging civil war between Béla IV and his son Duke Stephen.
Following the war, the Cuman territories became part of Stephen's realm, who adopted the title of junior king and lord of the Cumans () in 1262. Duke Stephen also married Elizabeth, daughter of Zeyhan, a Cuman chieftain. The first known person who held the dignity of judge of the Cumans was Gregory Monoszló, who mentioned in this capacity twice in 1269. There is a scholarly debate, whether Gregory II or his namesake son from the Monoszló kindred served as judge during that time. Nevertheless, Gregory III was Elizabeth's brother-in-law through his marriage and was also a member of Stephen's ducal court in the 1260s. Following the death of Béla IV, Stephen V succeeded his father as King of Hungary. With the appointment of Mojs II in August 1270 – also a relative of the King –, the Palatine assumed the title and became ex officio judge of the Cumans to relieve pressure on the king's jurisdictional powers. When the dignity of Palatine was divided to two office-holders sometimes in the 1290s, only the "Transdanubian" Palatine (e.g. Roland II Rátót) bore the title.
Tibor Szőcs notes, the dignity of judge of the Cumans remained only a theoretical role, as the second Cuman law never entered the soil of implementation. For the next decades, there is no diploma or other contemporary source which refers to the palatines' procedures related to Cuman issues. Only Palatine James Borsa mentioned a plundering of Cumans among his grievances during the period of feudal anarchy in 1306, but this remark connected to his own personal complaint (the Borsa estates laid near to the Cumans' lands and the kindred had a long-standing relationship with them) and not his dignity. Before the extinction of the Árpád dynasty (1301), the last Palatine who was also ex officio judge of the Cumans, was Amadeus Aba in August 1300. During the feudal anarchy and subsequent war of succession, when many oligarchs were styled palatines, the position temporarily devalued until the 1320s. Under this, the title of judge of the Cumans detached from the palatinal institution, prominent loyal barons of Charles I, for instance Thomas Szécsényi and Demetrius Nekcsei bore the title, in 1319 and 1328, respectively, but with limited jurisdiction.
