Alberto da Giussano
Alberto da Giussano (in Lombard Albert de Giussan, in Latin Albertus de Gluxano) is a figure who would have participated, as a protagonist, in the battle of Legnano on 29 May 1176. According to one historical study, the figure of Alberto da Giussano never existed and the actual military leader of the Lombard League in the famous military battle with Frederick Barbarossa was Guido da Landriano.
In the past, historians, attempting to find a real confirmation, hypothesized the identification of his figure with Albertus de Carathe (Alberto da Carate) and Albertus Longus (Alberto Longo), both among the Milanese who signed the pact in Cremona in March 1167 which established the Lombard League, or in an Alberto da Giussano mentioned in an appeal of 1196 presented to Pope Celestine III on the administration of the church-hospital of San Sempliciano. These, however, are all weak identifications, given that they lack clear and convincing historical confirmation.
