Jelena Šubić
Jelena Šubić (died 1378) was a member of the Bribir branch of the Šubić noble family who ruled the Banate of Bosnia as regent from 1354 until 1357.
Jelena was the daughter of the Croatian lord George II Šubić of Bribir, Count of Klis.
She married Vladislav, brother of Ban Stephen II of Bosnia, in Klis Fortress in late 1337 or early 1338.
Lampridio Vitturi, Bishop of Trogir, celebrated the marriage; Trogir authorities hostile to him later complained to the papacy that the marriage was uncanonical due to consanguinity of the couple.
Jelena and Vladislav had two sons, Tvrtko and Vuk.
Tvrtko was about 15 years old when he became Ban of Bosnia upon the death of her brother-in-law in the fall of 1353.
Jelena and Vladislav, who was excluded from succession for unknown reasons, assumed government in the name of the young Ban.
Widowed within a year, Jelena continued ruling on Tvrtko's behalf alone.
Accompanied by her younger son, Jelena immediately traveled to the court of their overlord, King Louis I of Hungary, to seek his consent to Tvrtko's accession.
Louis tasked her with delivering a message to her sister-in-law Jelena Nemanjić, widow of her brother Mladen III, who was trying to keep hold of the Kliss Fortress.
Upon her return to Bosnia, Jelena presided over an assembly ("stanak") in Mile and confirmed the possessions and privileges of the noblemen of "all of Bosnia, Donji Kraji, Zagorje and the Hum land".
In May 1355 she decided to take an active part in the dispute over the Šubić family inheritance, which had been ongoing since the death of her brother Mladen in 1348.
Jelena marched with Tvrtko and their army to Duvno.
An agreement was concluded by which her son was to inherit all cities held by her father and a city held by her sister Katarina.
Jelena's regency ended in 1357.
She and her sons were granted citizenship by the Republic of Venice in 1364.
Two years later she accompanied Tvrtko to the Hungarian royal court following his brief deposition in favor of Vuk; Tvrtko reinstated himself within a year.
In the fall of 1374, Jelena organized and attended the wedding of her son and Dorothea of Bulgaria.

Vuk, Ban of Bosnia
Vuk (died after 1378) was the Ban of Bosnia from 1366 until 1367, a member of the Kotromanić dynasty that ruled the Banate of Bosnia since the turn of the 14th century.
Vuk was the younger son of Vladislav Kotromanić and Jelena Šubić, who were married in 1337.
His brother, Tvrtko I, became Ban of Bosnia following the death of their paternal uncle, Stephen II, in 1353.
Their father acted as regent until his death in 1354, followed by their mother until Tvrtko reached the age of majority in 1357.
Vuk accompanied Jelena when she traveled to Hungary in 1354 to request consent to Tvrtko's accession from their overlord, King Louis I of Hungary.
In July 1357, Tvrtko and Vuk were confirmed as joint rulers of Bosnia and Usora by King Louis under two conditions: one of the brothers would be at Louis's court whenever the other is in Bosnia, and they would make an effort to suppress the "heretical" Bosnian Church.
In February 1366, Tvrtko faced a major revolt by his discontent vassals.
He and Jelena were forced to flee to King Louis's court, while Vuk replaced him on the ban's throne.
While he did take his role as ban seriously, it is not clear if Vuk instigated his brother's dethronement or if he was only a puppet installed by the nobility.
Within a month, however, Tvrtko returned aided by the Hungarian army.
By the end of March, Vuk had lost some of Bosnia to his brother, but retained control over Bobovac, the capital.
The nobleman Sanko Miltenović defected from Vuk to Tvrtko in the second half of 1367, bringing much of Zachlumia back under Tvrtko's control.
Vuk was finally deposed and exiled in late 1367.
Once exiled, Vuk attempted to gain outside help against Tvrtko; he particularly pleaded with Pope Urban V, as the Papacy had been advocating a crusade against the Bosnian Church for some time.
The King of Hungary's protection of Tvrtko rendered Vuk's chances of regaining the throne of Bosnia slim.
By 1374, the brothers had reconciled, possibly on the occasion of Tvrtko's marriage to Dorothea of Bulgaria.
Vuk remained in Bosnia, functioning as a junior ban and endorsing his brother's charters.
He is believed to have died after 1378.
