Giano Della Bella (c. 1240[1] Florence - France, before 19 April 1306) 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.[2]
He was born in the family castle within Florence into a Ghibelline (pro Holy Roman Emperor) 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.[3]
He was of noble birth[4] but also a member of the Arte di Calimala, the wool merchant's guild.[5]
