Rainuccio degli Allegretti

Rainuccio degli Allegretti (died 1348), of one of Volterra's leading families, was bishop of Volterra from 1321. Once parish priest at Morba and, from 1315, vicar-general to Bishop Ranieri Belforti, he was elected by the cathedral chapter in December 1320 and confirmed by John XXII in February 1321.

He set out at once to win back church lands that private holders had usurped. The commune answered by exiling his father and condemning other relatives. In 1322 he withdrew to Casole d'Elsa, opened a mint and excommunicated the Volterrans who had sent troops against Berignone castle.

He was back in the city by late 1323 and held a pastoral visitation of his diocese in 1325–1328, among the earliest in Tuscany. In 1340 Ottaviano Belforti took power in Volterra and expelled him and his family, and he spent his last years in the castles he still controlled, dying in 1348.
