Андраш III
By 1291, Mojs I was appointed Count of the Székelys. He appeared in the dignity (as the first known office-holder since 1228, when Bogomer Ludány held the office) on 12 March 1291, when King Andrew III of Hungary confirmed his predecessor Ladislaus' land donations to the Székelys of Aranyos Seat. He was succeeded by Peter Bő in the position by June 1294. Mojs Ákos briefly served as Master of the treasury from around October to December 1291, succeeding the rebellious Ivan Kőszegi. Mojs was replaced by Dominic Rátót still in that year. He was among the barons of Andrew III of Hungary in 1296. He served as Master of the treasury for Queen Agnes of Austria from 1298 to 1299.
