Rinaldo II d'Este

Rinaldo II d'Este (c. 1290–1335) was a son of Aldobrandino II d'Este. In July 1317 Ferrara's people expelled the Angevin rulers, acclaimed the Este and gave Rinaldo power. Pope John XXII excommunicated him, and after he received investiture from Louis the Bavarian in 1324, the pope launched a crusade against the Este.

Rinaldo later reconciled with the papacy and in 1329 received Ferrara as a papal vicariate with his brothers. In 1333 he routed a Bolognese army besieging Ferrara, and in June 1335 he conquered Modena, but died on 31 December 1335 before receiving its investiture.
