His origin is uncertain: according to a royal charter issued in 1233, he had a namesake son, who held the office of Master of the treasury from 1231 to 1235.
[2] In contemporary records, Nicholas was first mentioned as Ban of Slavonia in 1200, when Andrew, the brother of King Emeric held the royal title of Duke of Slavonia, therefore can be assumed that Nicholas was a loyal supporter of Andrew, who rebelled against the rule of his brother several times.
[9] From 1208 to 1210, he functioned as Judge royal,[10] while also held the ispán offices in Pozsony (1208 and 1211–1212),[11] Keve Counties (1208–1209 and 1209–1210).
[13] He was appointed Palatine for the second time in 1213, replacing Bánk Bár-Kalán, who had participated in the murder of Queen Gertrude.
[14] Former archontological works written by historians Mór Wertner and Gyula Pauler, stated that the 1213–1214 period was the first palatinal term of Nicholas Szák.
