Family and marriage
Yolande was born in Zaragoza, Aragon, on 11 August 1384, the eldest daughter of King John I of Aragon by his second wife, Yolande of Bar, the granddaughter of King John II of France. She had three brothers and two sisters, as well as five older half-siblings from her father's first marriage to Martha of Armagnac. Yolande later played an important role in the politics of England, France, and Aragon during the first half of the 15th century.
In 1389, Louis II was crowned King of Naples. His mother Marie of Blois opened negotiations for a marriage between her son and Yolande to prevent Aragon from obstructing his rule there. When Yolande was eleven, she signed a document to disavow any promises made by ambassadors about her marrying Louis II. In 1395, Richard II of England also opened negotiations for Yolande's hand. To prevent this marriage, Charles VI of France offered his own daughter Isabella to King Richard. After the death of Yolande's father, Marie of Blois convinced Yolande's uncle Martin I of Aragon to have Yolande wed Louis II. Yolande signed a protest, but was forced to retract it later. The couple married in Arles on December 2, 1400. Despite Yolande's earlier objections and the later illnesses of her husband, the marriage was a success.
