"Nagy" Tiborc; died after 1222) was a Hungarian distinguished nobleman at the turn of the 12th and 13th centuries, who served as ispán (head) of various counties during the reign of kings Emeric then Andrew II.
[2] Tiburtius was a confidant of King Emeric, whose whole reign was characterized by his struggles for the supreme power against his rebellious younger brother, Duke Andrew.
[6] Initially, Tiburtius and his family possessed landholdings in the namesake Rosd Island and the surrounding area on the other side of the river Danube in Pilis County, for instance Pomáz and Szencse.
The new monarch intended to reconcile the courtiers of his late brother, which allowed Tiburtius to return to the elite, although initially he received only nominal positions.
When their movement forced the monarch to ratify the Golden Bull of 1222, Tiburtius was installed as ispán of Pozsony County, where his major estates laid, but soon he was dismissed still in that year, when Andrew II regained his power.
