Ercole I utilized strategic marriage alliances to consolidate his political position and secure the House of Este against the shifting power dynamics of Renaissance Italy.
His own marriage to Leonora, daughter of the king of Naples, provided him with essential political support early in his reign. To further stabilize his rule and bind Ferrara to other major Italian powers, he arranged marriages for his children:1
- Daughters:
- Lucrezia was married to Annibale Bentivoglio of Bologna.1
- Isabella was married to Francesco Gonzaga of Mantua.1
- Beatrice was married to Ludovico Sforza of Milan.1
- Son:
- His eldest son, Alfonso, was married first to Anna Sforza of Milan and later to Lucrezia Borgia, daughter of Pope Alexander VI.1
These unions were instrumental in navigating the "troubled times" of his rule, helping him maintain authority despite external threats from coalitions like those led by Venice and Pope Sixtus IV.1
