After Niccolò's death in 1441, the ten-year-old Ercole could in theory have succeeded his father as his eldest legitimate child. However, her father instead left the title to his illegitimate son Leonello,[2] who exiled Ricciardia and her two children to Naples.[3]
Leonello reigned for nine years, and then was succeeded by his brother Borso, who reigned for a further 21 years. However, in the meanwhile Ricciarda had forged alliances that meant that on Borso's death she succeeded in getting Ercole made duke of Ferrara.[4]
