By 1314 Stephen had been succeeded by Stephen II, his eldest son by Elizabeth. She was ousted from Bosnia in 1314 and took refuge in Ragusa with her and Stephen I's children: Stephen II, Vladislav, Ninoslav (who died young) and Catherine (who married into the Nemanjić family of Zachlumia). Stephen II and Vladislav managed to reassert the family's hold on Bosnia, defeating the Šubić family in 1322. In the course of his reign Stephen II expanded the Kotromanić realm to its farthest limits thus far ("from the Sava to the seaside and from the Cetina to the Drina"), doubling Bosnia's territory. He was married two or three times: to a Bulgarian princess, to Elizabeth of Kuyavia, and possibly (firstly) to a daughter of Meinhard I of Ortenburg. He left two daughters: Elizabeth and Catherine. Elizabeth's marriage to King Louis I of Hungary in 1353 elevated the Kotromanić dynasty and was the most prestigious union in its history. Catherine's marriage to Count Hermann I of Celje was also of dynastic significance; the couple's son, Hermann II, was recognized as heir presumptive to the Bosnian throne in 1427, and through him the Kotromanić dynasty is ancestral to the presently reigning European kings and queens.
