[1] Elizabeth was a member of the Polish royal House of Piast, the daughter of Władysław I the Elbow-high, prince of Kuyavia, later King of Poland,[2] and Jadwiga of Kalisz.

[citation needed] Following her husband Charles Robert's death, Elizabeth wished to make a good marriage for her eldest surviving son, Louis.

She had her son betrothed to Margaret of Bohemia, daughter of Charles IV, Holy Roman Emperor.

[7] She intervened and made a state visit; before she returned to Hungary, she bribed the Pope to reverse himself and permit Andrew's coronation.

[7] She also gave her son a ring, which was supposed to protect him from death by blade or poison, and returned with a false sense of security to Hungary.

After her regency and her return to Hungary, Elizabeth spent her final years in a monastery outside of Buda, where she wrote her will.

Elizabeth also left money and possessions to her family: she left Louis several golden vessels, daughter-in-law, Elizabeth of Bosnia - Buda Castle, granddaughter, Mary - a gold wreath, granddaughter, Jadwiga - wreath of lilies, and her niece, Hedwig - a ring.

[9] The exquisite examples of Queen's foundation includes silver Reliquary Shrine with Virgin and Child from about 1350 in the Metropolitan Museum of Art, attributed to Jean de Touyl,[10] most probably created for the convent of the Poor Clares of the Order of Saint Francis at Buda, also founded by the Queen in 1334[9] and silver reliquary of Saint Nicholas in the form of a gothic church from 1344, attributed to Pietro di Simone Gallico in the Museo Nicolaiano in Bari.

[9][12] Queen Elizabeth is one of the supporting characters in Polish historical drama TV series "Korona królów" ("The Crown of the Kings").
