Eleanor of Aragon, Queen of Portugal

Eleanor of Aragon (2 May 1402 – 19 February 1445) was Queen of Portugal from 1433 to 1438 as the spouse of King Edward. After Edward's death, she served as regent in 1438-1440 for her son Afonso V. She was the daughter of Ferdinand I of Aragon and Eleanor of Alburquerque.

Biography
Eleanor's brother, Alfonso V of Aragon, arranged her marriage to the future King Edward of Portugal, which happened on 22 September 1428. They had nine children, of whom five survived to adulthood. In 1433, she became Queen of Portugal.

When her husband died on 9 September 1438, Eleanor was appointed regent of Portugal in his will, which was supported by the Portuguese Cortes. However, as a woman and a foreigner, she was unpopular with the people, who preferred the late king's brother Infante Peter, Duke of Coimbra. Her appointment as regent therefore caused a riot in Lisbon. The riot was suppressed by her brother Count John of Barcelona, later King John II of Aragon. Eleanor was supported by the nobility and the will, while Peter was supported by a fraction of the nobility and by the people. Negotiations for a compromise arrangement were drawn out over several months. Eleanor was at first prepared to divide the regency between herself and Peter, but the interference of the Count of Barcelos and other nobles that sided with her complicated matters and she was ultimately dissuaded. In March 1439, Eleanor gave birth to a posthumous daughter, Joan, and her eldest daughter, Philippa, died. Eleanor's poor health and grief from losing her daughter caused her to withdraw from state affairs, further enraging the people.

Eventually, the Cortes appointed Peter the sole regent. Eleanor continued conspiring, but decided to flee to Castile in December 1440, bringing her infant daughter Joan with her.

Dependent on charity and longing to be reunited with her children, Eleanor was deeply unhappy in Castile. In 1444, she applied to return to Portugal, but died at Toledo in February 1445. There were rumors that she was poisoned. In 1457, Afonso V ordered the transfer of her remains to Batalha, Portugal, where she is now buried alongside her husband in the Batalha Monastery.
