The Cacciaconti were an ancient family from Siena, whose origins are traced back to the great feudal consortium of the Berardenghi of Salic origin. The origins of the Cacciaconti are traced back to the great early medieval consortium of the lords of Berardenga, descendants of Winigisio I of Raghinerio, of Salic origin, who was count of Siena and Roselle in the second half of the ninth century.
The Cacciaconti were lords of numerous castles in Siena: Asciano, from which the name of Scialenghi or Scialenga, Rapolano, Scrofiano and Trequanda. They urbanized in Siena around between the twelfth and thirteenth centuries.
Among the illustrious figures of this family are Caccia d'Asciano and Ghino di Tacco, both mentioned by Dante Alighieri in the Inferno.
