Giano della Bella

Giano Della Bella was a late thirteenth century Florentine politician and a leader of the revolt that brought in the Ordinances of Justice which entrenched the power of the Florentine guilds by excluding aristocrats from power in Florence.
He was born in the family castle within Florence into a Ghibelline family, although he became a Guelph and a populist.
In 1294 he was podestà of Pistoia. He is the protagonist of the first chapters of Dino Compagni's Nuova Cronica and is also mentioned by Dante in Paradise.
He was of noble birth but also a member of the Arte di Calimala, the wool merchant's guild.
