Nino Visconti

Ugolino Visconti, known as Nino (c. 1265 – August 1296), was judge of Gallura from 1275, succeeding his father John. Exiled with his father in 1274, he later returned to Pisa and became a leader of its Guelph party, serving the city as capitano del popolo and podestà.

In 1288 his grandfather Count Ugolino and Archbishop Ruggieri turned against him; Ruggieri drove him into exile and seized his giudicato. Nino fought back with Genoa, Lucca and Florence. He married Beatrice d'Este, his daughter Joanna inherited Gallura, and his friend Dante places him in Purgatorio.
