Vladislaus of Bosnia

Vladislav of Bosnia (; died 1354) was a member of the House of Kotromanić who effectively ruled the Banate of Bosnia from September 1353 to his death.

Vladislav was a younger son of Stephen I, Ban of Bosnia, and Elizabeth of Serbia. Upon the death of Ban Stephen I in 1314, Vladislav's mother assumed regency in the name of his older brother, Ban Stephen II. Unclear circumstances soon forced her to flee Bosnia and seek refuge in the Republic of Ragusa. She took her children with her, and Ragusan documents show they spent several years there in exile. 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. By the summer of 1319, the Kotromanić family were back in Bosnia. 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. The brothers then proceeded to assist the Ban of Slavonia in conflicts with Croatian magnates. appears as co-granter of Stephen II's charters to the Hrvatinić noble family between 1326 and 1331. They nevertheless stayed together and had two sons, Tvrtko and Vuk. Tvrtko, however, was only about 15 years old at the time, so Vladislav assumed the reins of government with his wife. He immediately took the young Ban on a tour throughout Bosnia, during which they settled relations with vassals.
