Gyula; died 1237) was a powerful Hungarian baron and landowner, who held several secular positions during the reign of kings Emeric, Ladislaus III and Andrew II.
[1] Julius I (often called as "the Elder" or "the Great" by contemporary documents in order to distinguish him from his namesake son) was the first known member of the gens (clan) Kán, which originated from Baranya County, but later acquired large-scale domains in Transylvania too.
The later members of the clan were usually styled themselves as "Progenies Magni Jule Bani" ("descendants of Ban Julius the Great").
[1] His great-grandson was Ladislaus III Kán, an infamous oligarch, who ruled the province Transylvania de facto independently of the royal power for decades.
[10] The first surviving palatinal charter in its entirety was also issued by Julius in 1216, when instructed the cathedral chapter of Várad, a place of authentication (today Oradea, Romania) to record in writing one of his previous judgments in a litigation case.
[11] During Andrew II's Fifth Crusade (1217–1218), Julius and royal governor John, Archbishop of Esztergom could not prevent the emergence of anarchic conditions, as a result he lost his political influence for a short time.
[16] After the death of Andrew II in September 1235, Julius had been disgraced and was imprisoned by the new king, Béla IV of Hungary, who also confiscated all of his property.
Historian Mór Wertner identified all occurring Julius with the person from the kindred Kán during the first decades of the 13th century, unless he had no reason to act differently.
