The Suffredinghi were one of the noble houses that played an active role in the Upper Serchio Valley and were long recognized as the lords of Anchiano and the Fort of Mozzano even though their power extended over numerous fortified locations in the area. For a long time the luck of these nobles was linked to the fact that they did not directly oppose the expansionist ambitions of the City of Lucca. However, as soon as they finally took sides against Lucca they were hit hard in their most prized lands. Indeed, Anchiano and the Fort of Mozzano were both heavily damaged.
