Isabella of Aragon, Duchess of Milan (d. 1524)
Isabella of Aragon (2 October 1470 – 11 February 1524), also known as Isabella of Naples, was Duchess of Milan by marriage to Gian Galeazzo Sforza and suo jure Duchess of Bari. Her life was characterised by the political crises surrounding the Italian Wars. Isabella often found herself torn between her native Kingdom of Naples and her marital home of the Duchy of Milan, causing her to suffer personal and political difficulties. After a difficult marriage and lack of support in Milan, she received the Duchy of Bari. This change in circumstances gave Isabella the opportunity to form her own court as well as build up political support and security against the ongoing wars. These reforms along with her interest in arts and literature, resulted in Bari undergoing revival and refurbishment. During this period, she also concentrated on the education of her daughter Bona, who became Queen of Poland.
