Giovanni Manfredi
Giovanni Manfredi (1324–1373) was the Manfredi who lost Faenza to the Church. Born in Imola, an illegitimate son of Riccardo Manfredi, he was lord of Faenza from 1341 to 1356.
In 1351 he took Bernabò Visconti's pay in his war against Bologna and the Papacy, for which he was excommunicated in 1352. In 1356 a crusade was proclaimed against him and his ally of Forlì.
After a long resistance he surrendered Faenza to the papal commander, Cardinal Albornoz. In 1361 he rebelled again, but his plans to take Faenza and Imola were discovered, and he died at Pistoia in 1373.
