The 16th-century chronicler Mavro Orbini states that only Stephen followed Elizabeth, while Vladislav and his brother Ninoslav went to the Croatian town of Medvedgrad.
Vladislav and Stephen took part in a great coalition of noblemen against their overlord Mladen II Šubić of Bribir, causing his downfall and bringing the House of Kotromanić directly under the suzerainty of King Charles I of Hungary.
[2] Vladislav, titled knez,[1] appears as co-granter of Stephen II's charters to the Hrvatinić noble family between 1326 and 1331.
For reasons unknown, Vladislav was excluded from succession, and the title Ban of Bosnia passed directly to his son Tvrtko.
[2] Despite his son being the enthroned ruler, Vladislav's name took precedence in charters, suggesting that the Ban was eclipsed by his father.
