Iban von Bernstein
He was born in the 1300s, not long before the death of his elderly father (April 1308), as he first appeared in contemporary records only in 1325, and Ivan's province in Western Transdanubia was inherited by John's nephews Nicholas III, then Andrew, who were definitely older than their uncle.
[3] In addition, John had a stepbrother from his father's extramarital affair, Nicholas (born 1282), who entered ecclesiastical career and elevated into the dignity of Bishop of Győr.
Von Bernstein inherited Andrew's lands, becoming head of the Kőszegi family's Ivan branch, who once governed their dominion independently of the monarch, consisting of Győr, Moson, Sopron, Vas and Zala counties and other lands, but the family was able to retain only Vas County after Andrew's failed rebellion in 1317.
Charles I of Hungary ordered the chapter of Vasvár in July to investigate the act of domination, but John's instigator role has not been proved.
In August 1325, John issued a charter in Sárvár that he had donated the estates of Hidegség and Fertőhomok to the Blessed Virgin church of Felsőkethely (present-day Neumarkt im Tauchental, a borough of Stadtschlaining in Austria), in accordance with his nephew's will.
The pope also appointed Henry, Bishop of Veszprém as Nicholas Kőszegi's defender ("conservator") in June in order to restore benefice of the diocese.
Accordingly, he transuded private information to the Holy See about the bishop's parentage, in order to turn him out of office, and occupied Szombathely and other bishopric estates in Vas County.
During the military campaign, Köcski seized Sárvár, Németújvár (present-day Güssing, Austria) and two other forts in Kőszeg with surrounding villages and lands from John.
Charles provided Köcski broad power in the redistribution of lands to the loyal local nobility and he had the mandatory of royal grace to the Kőszegis' former familiares, of whom many left John's allegiance.
In the document, he returned the estate of Pózva (today a borough in Zalaegerszeg) to the sons of Kalmer Geregye, which was demolished by Ivan Kőszegi decades earlier.
[14] Iban married Agnes (died before 1363), the daughter of captain Eberhard V von Wallsee, which resulted his rapid integration into the Austrian nobility.
[11] He appeared as arbitrator, witnesses and countersigning noble in several legal documents, contracts and lawsuits, of which the Wallsee family were involved in the upcoming decades.
Among other lords, Iban acted as a councillor in the lawsuit between Vienna and Wiener Neustadt over wine delivery and sale in November 1358.
He also functioned in this capacity, when the duke established the St. George chapel in Enns in late 1361, after his victory over Lodovico della Torre, Patriarch of Aquileia.
He countersigned that document, which granted Leopold control over Tyrol, Further Austria and Carniola while income would be split between the dukes in July 1373.
[16] In order to finance his dukes, Iban also had to apply for loans; at the end of his life he was owed to three Jewish traders in Neunkirchen.
Three years later, Iban also sealed that document in Vienna in which Nagymartoni promised does not offer to take shelter for those who robbing and tearing Austria.
As historian Renáta Skorka analyzed, the formerly rebellious Graf Iban, who plundered and looted the borderland of the two realms several times, continuing his father's activity, became guardian and promoter of those Hungarian nobles, who entered the service of the Habsburgs, and helped maintain the lawful order in Styria and Lower Austria by the end of his life.
