Elizabeth of Kuyavia
Elizabeth of Kuyavia(/ Елизабета; 1315/ 1320 – after 22 August 1345) was a Polish noblewoman of the House of Piast.
She was the only daughter of Duke Kazimierz III of Gniewkowo and his wife, whose name and origins are unknown; her brother, Władysław the White, was later a candidate for the Polish throne.
By 1323, King Charles I of Hungary wanted to increase influence over Stephen II, Ban of Bosnia.
He offered Stephan the hand of Elizabeth, the relative of his own Piast wife Elizabeth.
By marrying Elizabeth of Kuyavia, Stephen received from Charles the lands to the west formerly held by Mladen I Šubić of Bribir and Usora and Soli in the north formerly held by Vladislav, King of Syrmia.
The marriage was celebrated by 1339.
Up to 1339, Stephan was married to an unknown Bulgarian princess.
The only child which can be attributed to Elizabeth of Kuyavia without doubt is Elizabeth of Bosnia, born c. 1340.
Some believe that Catherine of Bosnia, Countess of Cilli, was daughter of Elizabeth of Kuyavia and Stephen II, while others argue that Catherine was daughter of Stephen II's brother Vladislaus and his wife Jelena Šubić.
Elizabeth may have also had a son, Vuk who may have survived infancy but he did not outlive his father so never became Ban of Bosnia.
Vuk may have been the son of one of Stephen's previous two wives.
Stephen outlived Elizabeth.
It is unknown what Elizabeth died of.
Judging by the time, it is possible that she died of Black Death, which was sweeping across Europe during the 14th century.
Banness Elizabeth was buried in Bobovac in a tomb which she shared with her husband, brother- in- law Vladislaus and sister- in- law Jelena.
After Elizabeth of Kuyavia's death, her daughter Elizabeth was fostered by the Hungarian queen dowager Elizabeth and this soon led to Elizabeth's marriage to Louis I of Hungary.

He was the oldest son of King Béla IV and Maria Laskarina.
King Béla had his son crowned king at the age of six and appointed him Duke of Slavonia.
Still a child, Stephen married Elizabeth, a daughter of a chieftain of the Cumans whom his father settled in the Great Hungarian Plain.
King Béla appointed Stephen Duke of Transylvania in 1257 and Duke of Styria in 1258.
The local noblemen in Styria, which had been annexed four years before, opposed his rule.
Assisted by King Ottokar II of Bohemia, they rebelled and expelled Stephen's troops from most parts of Styria.
After Ottokar II routed the united army of Stephen and his father in the Battle of Kressenbrunn on 12 July 1260, Stephen left Styria and returned to Transylvania.
Stephen forced his father to cede all the lands of the Kingdom of Hungary to the east of the Danube to him and adopted the title of junior king in 1262.
In two years, a civil war broke out between father and son, because Stephen accused Béla of planning to disinherit him.
They concluded a peace treaty in 1266, but confidence was never restored between them.
Stephen succeeded his father, who died on 3 May 1270, without difficulties, but his sister Anna and his father's closest advisors fled to the Kingdom of Bohemia.
Ottokar II invaded Hungary in the spring of 1271, but Stephen routed him.
In next summer, a rebellious lord captured and imprisoned Stephen's son, Ladislaus.
Shortly thereafter, Stephen unexpectedly fell ill and died.
