Joanna of Aragon (, ; 16 June 1455 – 9 January 1517) was Queen of Naples as the second wife of King Ferdinand I. She served as regent (General Lieuntenant) of Naples between the abdication and flight of king Alfonso II 22 February 1495 until the formal succession of Ferdinand II of Naples. Born in Barcelona, Joanna was the second child of King John II of Aragon by his second wife, Juana Enríquez de Córdoba, and his youngest legitimate child. Queenship 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. After the wedding on 14 September the contract was signed in Navarre, on 5 October 1476 and the agreement was ratified on 25 November. John II gave his daughter a dowry of 100,000 gold florins and Ferdinand gave his new wife many duchies and/or cities, such as Sorrento, Theano, Isernia, Teramo, Sulmona, Francavilla and Nocera. He also gave her more than 20,000 ducats annually. 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. She arrived on 1 September 1477. 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. Their first child was born in 1479 and another child arrived in 1480. Joanna showed a tendency to resolve political affairs. 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. A few years later, after the conspiracy was suppressed, Joanna returned to Abruzzo, accompanied by her daughter Joanna. They visited most of the monasteries in L'Aquila that year. Queen Dowager On 25 January 1494, Ferdinand I died aged 71. He was succeeded by his eldest son Alfonso, and step-son of Joanna, who became queen dowager. From this point on, Joanna signed every letter with the phrase the sad queen (Old Italian: la triste reyna). Because of the grief, she did not even attend her step-son's coronation on 8 May 1494. In return, Alfonso gave his step-mother the position of Lieutenant General of the Kingdom of Naples. Meanwhile, King Charles VIII
