Overview
Helen (; 1345 – after 18 March 1399), also known by the name , ruled the Kingdom of Bosnia from September 1395 until late April or early May 1398. She was queen consort as the wife of King Dabiša, and was chosen by the stanak to rule after his death. Whether she was a regent who ruled during an interregnum or a queen regnant is disputed, but in any case the real power was held by magnates of the kingdom. Her rule ended with the election of King Ostoja.
Family
Nothing is known for certain about Helen's origin. She was most likely a member of the Nikolić noble family from Zachlumia.
A charter dated 17 July 1392 is the earliest extant source naming Helen as queen and wife of Dabiša, who had succeeded Tvrtko I in March 1391, and places her at Dabiša's side in Lušci. As queen consort, Helen endorsed her husband's acts, and he emphasized in his charters that he had consulted with his wife. Queen Helen's family gained significant influence in state affairs during her husband's reign, as well as the right to collect the tribute of Ston from the Republic of Ragusa in 1393. The royal couple had a daughter named Stana, whose daughter Vladava married the nobleman Juraj Radivojević during Dabiša's lifetime.
