(Léka), owned by Nicholas Kőszegi and his sons until 1340 Nicholas was first mentioned by contemporary records in March 1314, when he and Ivan's grandson
Andrew returned the previously seized
Sobor to their
familiares, the members of the
gens (clan) Osl, including
Lawrence. In the autumn of 1315,
Charles I launched his first large-scale campaign against Nicholas' cousins,
John and
Peter (Henry II's sons) and their territory. Charles personally led his troops into
Tolna County. However John sought assistance from his relatives, Andrew, who administered Western Transdanubia and Nicholas II; they represented the other two branches of the Kőszegi family. The united Kőszegi troops managed to expel the royal army from the region. In February 1316, Nicholas issued a letter of donation to his
familiaris, Stephen Vönöcki for his loyalty and role in the victorious campaign against the royal troops. There was a political turnaround in Nicholas' career in the upcoming months. When
Stefan Uroš II Milutin invaded the
Syrmia, Charles I launched a counter-campaign across the river
Száva and seized the fortress of
Macsó (present-day Mačva, Serbia) in the winter of 1317. Nicholas pledged allegiance to the king and also participated in the campaign, according to Pál Engel. Taking advantage of the king's absent, Andrew Kőszegi attacked the royalist towns of
Sopron and
Győr and, simultaneously, he unsuccessfully besieged Léka and Rohonc too, the castles of Nicholas II. During the attack, Andrew's troops killed Nicholas' several servants and pillaged their lands, but Nicholas'
familiares, Gregory and Duruslaus Rumi managed to repel the invasion itself. In retaliation, Charles launched a punitive expedition against Andrew's territory in the summer of 1317, while Austrian duke
Frederick the Fair also attacked from the borderlands. Andrew's dominion collapsed within months. Charles' cease-fire conditions resulted the dissolution of the extended Kőszegi province in Western Transdanubia. Charles I supported Nicholas, implementing the strategy of "
divide and rule" in order to eliminate the Kőszegis' united actions; the king appointed him as
ispán of Vas and Zala counties, succeeding Andrew. Beside that Nicholas was also made
Master of the horse in late 1317 or early 1318. After his ultimate victory over most of the oligarchs, including the Kőszegi kinship, Charles I turned against Nicholas and declared him as treacherous. In early 1321, Charles' generals,
Alexander Köcski and Lawrence Csornai (Nicholas' former
familiaris) again led a royal campaign in Transdanubia. At first, they captured Pölöske, then seized Kanizsa and Rohonc, along with several villages. Nicholas Kőszegi could retain only Léka, while the ispánate of Vas County went to his former rebellious relative, Andrew Kőszegi. ==Later life==
