[2] His only known son was Maurice II, Nicholas' father, who held several positions (most notably Master of the treasury) in the court of King Béla IV at least until 1269.
After Maurice's death, the brothers jointly owned Pok, Tét, Baráti and Mórichida in Győr County, along with other sporadic lands throughout the kingdom.
[7] Through his granddaughter Anne, Nicholas Pok was also maternal ancestor of the royal house of Báthory de Somlyó, which ruled in Transylvania and Poland in the 16th century.
[3][9] Nicholas was donated five villages – Sárköz (Livada), Avas and Újváros (Orașu Nou), Vámfalu (Vama) and Parlag (Prilog) – by Stephen V in 1270 for possible former military achievements during the 1260s civil war.
[10] However his lord suddenly fell ill and died in August 1272, following Ban Joachim Gutkeled kidnapped Stephen's ten-year-old son and heir, Ladislaus and imprisoned him in the castle of Koprivnica.
[11] During that time two rival baronial groups emerged (supporters of the minor Ladislaus and former partisans of the late Béla IV, who returned to Hungary after Stephen's death), while the royal power was fatally weakened.
[14] Following that, when Ottokar II of Bohemia invaded Hungary and seized many fortresses, Nicholas participated in the Siege of Nagyszombat (today Trnava, Slovakia).
[17] Several news reports and diplomas say that Nicholas Pok continued to plunder the Transdanubian churches in the following years, while he also invaded Tapolca in Zala County around 1278.
They attacked and ravaged the church property in Tapolca, Csököly and Görgeteg, while also devastated the episcopal village Hegymagas, slaughtering the local population.
In retaliation, besides the punishment of excommunication, Peter Kőszegi's troops raided the family monastery of the Pok clan in the namesake village near Győr.
Albeit Nicholas was one of the "oligarchs" in the Kingdom of Hungary plagued by anarchy, civil wars and fragmentation, he has not so much notorious like Matthew Csák, Amadeus Aba or Ladislaus Kán.
Nicholas and his brothers possessed contiguous lands, the Somlyó lordship (present-day Șimleu Silvaniei, Romania) in the region of Szilágyság (Sălaj).
[4] On 26 September 1280, Mojs II wrote his last will and testament, bequeathed his Transylvanian properties of Zolun and Meggyes (today Medieșu Aurit, Romania) to his daughter, the wife of Nicholas.
[29][30] According to historians Gyula Kristó and János Karácsonyi, Nicholas fought in the Battle of Rozgony on 15 June 1312, where the Aba dominion was annihilated.
Given his extensive estates, Nicholas may have been large number of loyal and reliable familiares, so he could quickly mobilize a serious force in a military campaign against the Kán dominion.
In the surrounding lands, Nicholas Pok was the most influential pro-Charles lord, who meant a counter-balance against the Káns' suppression for the local lesser nobles.
[36] Upon the order of Charles I, Nicholas crossed the north border of the province at Zilah (today Zalău, Romania), because Mojs II Ákos, an ally of the Borsa clan, had rebelled against the monarch.
[37] Nicholas reached Kolozsvár (today Cluj-Napoca, Romania) in the middle of November 1315, however the following campaigns have failed against Mojs Ákos in Kolozs County.
[41] Kádár argued Nicholas chose Meszes Gate, because he tried to mobilize his spacious kinship and the royal nobility of the northeastern part of the country in the first instance.
[36] However historian Attila Zsoldos, who also examined the contents of Nicholas Pok's charters, in addition to the dates and locations, challenged Kristó's interpretation in 2016.
He argued, if, as Kristó considered, Nicholas Pok arrived to prepare a war to Transylvania immediately after his appointment, he would not have dealt with insignificant estate affairs in his diplomas as he did.
Zsoldos considered, the 1318 charter, which narrated the Voivode's appointment and the following events, twisted the years and Mojs was declared the king's enemy retroactively.
Following at least one-year vacancy he was replaced by the skilled military leader Dózsa Debreceni who successfully fought against the Kán clan and Mojs Ákos and later also became Palatine of Hungary.
