The royal authority weakened after Tvrtko I's death but the "stanak", the assembly of Bosnian noblemen, consistently elected members of the Kotromanić family to the throne. Tvrtko's successor, Dabiša (), likely an illegitimate brother or possibly a cousin, recognized as his heir the Hungarian king Sigismund, son-in-law of Stephen II's daughter Elizabeth. The Bosnian nobility refused to accept Sigismund as their king upon Dabiša's death on 8 September 1395, and instead elected Dabiša's widow, Helen (Gruba). Dabiša and his wife had a daughter, Stana, who left further issue.
