Mika Ják
Mika (I) from the kindred Ják (; died after 1202) was a Hungarian influential lord in the Kingdom of Hungary at the turn of the 12th and 13th centuries. Family. Mika (also Mike or Michael) belonged to the "gens" Ják, he was the first known member of the Jákmonostor branch. He had at least two children from his unidentified wife: Csépán I, who served as Ban of Slavonia from 1206 to 1207 and died without heirs, as his only son Stephen became a monk, giving up his secular life and family name. Mika's second son Ivan had two  sons (Martin I and James) thus the later members of the Jákmonostor branch descended from him. Mika founded the Pornó Abbey but the monastery itself was finished only by his son Csépán. Career. He served as Master of the treasury () in 1198, when this dignity was still a non-permanent position without defined and circumscribed jurisdiction, thus the office was only stabilized during the reign of Andrew II of Hungary. Mika also held the office of "ispán" of Bihar County between 1198 and 1199. In 1199, he was appointed Judge royal (), replacing Peter, son of Töre. When Palatine Mog participated  in Duke Andrew's conspiracy, Emeric, King of Hungary dismissed and replaced him with Mika Ják. However the appointment proved to be complicated procedure. According to Emeric's letter to Pope Innocent III, Mika was excommunicated by Elvin, Bishop of Várad because he had formerly captured one of the bishopric's priests, who functioned as a messenger of the King's enemies who supported Duke Andrew. Later Pope Innocent III ordered the Hungarian prelates not to degrade the excommunication as a political weapon, as a result Mika was able to reserve his office, who also served as "ispán" of Bács  County (1199–1200), which presumably was the first "ex officio" ispánate of the Palatine dignity, and after that head of Bihar County (1200–1201). According to a non-authentic charter, Mika held the office of Palatine until 1202. As historian Attila Zsoldos proves by comparing with the previous allegations, Palatine Mika was not identical with his namesake, who served as "ispán" of Bihar County for several times in the 1210–20s.
