Campaldino is one of the important battles between the Guelphs and Ghibellines--the major political factions in the city states of central and northern Italy. It heralded the rise of Florence to a dominant position over the area of Tuscany and was one of the last occassions when the Italian city militias contested a battle, with the 14th century seeing the rise of thecondottiere in Italy's Wars. In this highly illustrated new study, renowned medieval historians Kelly De Vries and Niccolò Capponi have uncovered new material from the battlefield itself, as well as using all the available sources, to breathe new life into this colorful and fascinating battle.
