Joanna of Aragon (Spanish: Juana, Italian: Giovanna; 16 June 1455 – 9 January 1517) was Queen of Naples as the second wife of King Ferdinand I.
King Ferdinand I of Naples, an illegitimate son of her uncle Alfonso V of Aragon, asked Joanna's hand in marriage from John II and he accepted.
[2] Alfonso, Duke of Calabria, eldest son of the king from his first marriage, sailed to Spain on 11 June 1477 in order to bring Joanna to Naples.
The formal wedding, with both the bride and groom present, took place on 14 September 1477 and was officiated by Rodrigo Borgia, the future Pope Alexander VI.
In August 1485, she started to randomly journey through Italy, probably to ensure loyalty to her husband in the wake of rebellions led by Baron Antonello Sanseverino and supported by Pope Innocent VIII and Cardinal Giulio della Rovere.
However Ferdinand II died of malaria in October of the same year and Joanna was left a childless widow aged seventeen.
In fact, when Frederick's reign began, Joanna resigned her position as lieutenant general and expressed her desire to move to Aversa.
