Blanche was the second eldest daughter of King Charles III of Navarre[2] and infanta Eleanor of Castile. She became the heiress to the throne of Navarre on the death of her elder sister, Joan, in 1413.

Queen regent of SicilyEdit

Blanche married firstly Martin the Younger, King of Sicily and Prince of Aragon.[2] They were married by proxy on 21 May 1402 in Catania. Blanche traveled to meet Martin, and they were married in person on 26 December 1402. The bride was about 15 years old and the groom 28.

Martin had been in need of legitimate heirs, as he had survived his previous wife and former co-ruler, Queen Maria of Sicily, and their only son. From October 1404 to August 1405, she served as regent of Sicily during the absence of her spouse in Aragon.

From August 1408 to July 1409, she served as regent of Sicily during the absence of her spouse in Sardinia. When Martin died on 25 July 1409, he was succeeded by his own father, Martin I of Aragon.[3] Her former father-in-law allowed her to continue as regent of Sicily, which she did also after his death,[4] during the years of succession struggle in Aragon. She was a popular regent in Sicily, where she was seen as a symbol of Sicilian independence against Aragon, and Bernardo Cabrera made an unsuccessful attempt to abduct her to marry Nicolas Peralta, a descendant of the Sicilian royal house, and thereby restore the Sicilian royal house with her and Nicolas as king and queen.

With the victory of Ferdinand I in Aragon, Blanche lost her regency power in Sicily, which was annexed to Aragon in November 1415, and left for Navarre.

Queen regnant of NavarreEdit

Upon her return to Navarre, Blanche was sworn in as heir to the throne in Olite the 28 October 1415 and was given allegiance by the lords. On 6 November 1419, Blanche married her second husband, John,[2] duke of Peñafiel, the second son of Ferdinand I of Aragon and Eleanor of Alburquerque, by proxy in Olite. Ferdinand had succeeded his maternal uncle Martin I in 1412.

John travelled to meet her. On 10 June 1420, they were married in person in Pamplona. The couple first lived in Peñafiel, but were called to live in Navarre by her father in 1422.

Charles III died on 8 September 1425 and Blanche succeeded him as Queen regnant of Navarre.[2] John became King of Navarre in her right as John II,[2] and the couple were crowned together in Pamplona 15 May 1429.

Blanche died in Santa María la Real de Nieva in 1441. After her death, John kept the government of Navarre in his own hands, from the hands of their own son Charles of Viana, the rightful heir of the line of Navarrese kings. He would become King of Aragon and King of Sicily upon the death of his elder brother Alfonso V of Aragon in 1458.


Blanche and Martin had one child together:

Blanche and John II of Aragon had four children together:


  1. ^ Anthony (1931) states that she was the fourth-born daughter of King Charles III of Navarre by Queen Eleanor, and she was preceded by Joan, Maria and Margaret and the two latter died early. Anthony defines Blanche's exact birth date as 6 July 1387 by virtue of contemporary sources.
