Isabella of Naples

Isabella of Naples (2 October 1470 – February 11, 1524) was the daughter of King Alphonse II of Naples by his wife, Ippolita Maria Sforza. From 1489 to 1494, she was the Duchess consort of Milan, and from 1499 to 1524 the Duchess of Bari and Princess of Rossano. After her brother Ferdinand II's death, she was the heir of the Brienne claim to the title King of Jerusalem.

She married her first cousin, Gian Galeazzo Sforza, who at the time was the Duke of Milan. However, his uncle Ludovico Sforza was the de facto ruler.

With Gian Galeazzo Sforza she had one son and two daughters:

• Francesco, who was taken to France by the French King Louis XII. in 1499,
• Bona, who married King Sigismund I of Poland,
• Ippolita Maria.

Isabella also outlived Francesco, who was killed in 1512 by falling from his horse. Of her three children, only Bona survived her.
