Ferdinand II had named Ferdinand as his heir in his will before being persuaded to revoke this bequest and rename Joanna and Charles I as his heirs-presumptive instead. When Ferdinand II died in 1516, the Kingdoms of Castile and León, and Aragon and their associated crowns and territories/colonies, would pass to Joanna I and Charles I. With Charles I still in Flanders, Aragon was being governed after Ferdinand II's death by his bastard son, Alonso de Aragón. Meanwhile, Castile and León, already subjects of Joanna, were governed by Archbishop Cisneros as regent. A group of nobles, led by the Duke of Infantado, attempted to proclaim the Infante Ferdinand as King of Castile but the attempt failed.
