Costanza d'Avalos, Duchess of Francavilla
Duchess of Francavilla|
Princess of Francavilla
|Spouse(s)||Federico del Balzo (1477-1483)|
|Father||Iñigo I d'Avalos|
After she was widowed without children, in 1483, King Frederick of Naples granted her the Duchy of Francavilla in 1501. She then followed her brother, Innico II d'Avalos, to Ischia, where he died in 1503.
Later that year, she defended Ischia against the French for four consecutive months, with great skill and bravery. Her services were rewarded by the settlement of the civil and military government of the island on the d'Avalos family, which power it retained until 1734, when its military command was transferred to Naples. She established her court at Ischia, which was frequented by many Neapolitan intellectuals of the period.
On 13 June 1507, she signed a marriage contract between her nephew Fernando Francesco d'Ávalos and Vittoria Colonna. The marriage took place on Ischia in December 1509. Vittoria, shortly after her marriage, spent her time on Ischia with Costanza.
She died in 1541 after Charles V had given her the title of Princess of Francavilla.
