Alfonso II dāEste failed to secure the future of the Este dynasty in Ferrara primarily because he died without a legitimate heir despite entering into three marriages.1
His efforts to preserve the family's rule were further undermined by the following factors:
- Papal Restrictions: In 1567, Pope Pius V explicitly forbade the succession of illegitimate children in ecclesiastical lands, which prevented Alfonso from securing the duchy through non-marital heirs.1
- Succession Dispute: Although Alfonso bequeathed the duchy to his cousin Cesare upon his death in 1597, Pope Clement VIII refused to recognize this settlement, declaring Cesare illegitimate.1
- Papal Incorporation: Following the dispute, the Pope successfully incorporated the duchy of Ferrara into the Papal States in 1598, establishing direct papal rule and effectively ending the main branch of the Este family's governance in the region.12
Disappointed by these circumstances, Alfonso had allowed the state's conditions to decay toward the end of his reign.1
