John Babonić

John Babonić (Croatian: Ivan Babonić, Hungarian: Babonics János; died c. 25 July 1334) was an influential Croatian baron and military leader at the turn of the 13th and 14th centuries, who served as Ban of Slavonia from 1316 to 1322, briefly also Ban of Croatia and Dalmatia in 1322.

He was a member of the powerful Babonić family which ruled Lower Slavonia since the 1270s, establishing an oligarchic domain there. As a kinsman of the Counts of Gorizia and Tyrol, he participated in various military campaigns to the Patriarchate of Aquileia. Following the death of his brother in 1316, he was eleveated into Ban of Slavonia, inheriting his province. As a royal baron of Charles I of Hungary, he fought against the Kőszegi family in Upper Slavonia and crushed the power of the Šubić family in Croatia and Dalmatia. He was dismissed as ban in late 1322, and the Babonići gradually lost power and influence in the region thereafter. After 1326, John acquired lands in Hungary.
