Folco II d'Este

Folco II d'Este (born c. 1300) was the designated heir to the lordship of Ferrara. The son of Fresco d'Este, he was named to succeed his grandfather Azzo VIII in his will. When Azzo died in 1308 his father ruled as his guardian, but his great-uncles contested the succession and appealed to Pope Clement V.

Ferrara rose against Fresco, who withdrew and sought Venetian help. A papal army seized Ferrara in 1309, and the city remained under direct papal control for years. Fresco and Folco took refuge in Venice, where both died in exile.
