Fresco d'Este

Fresco d'Este (c. 1280–1312) was an illegitimate son of Azzo VIII d'Este, lord of Ferrara. In 1308, the people of Ferrara appointed him guardian of his son Folco, whom Azzo had named his heir. His uncles Aldobrandino and Francesco challenged the succession and appealed to Pope Clement V.

When Ferrara rebelled against him, Fresco sought Venetian aid and then retired to Venice. In 1309 papal troops defeated the Venetian army and took Ferrara for the Papal States. Fresco remained in Venice with Folco until his death in 1312.
