War of the Lombard League

The Lombard League (Italian and Lombard: Lega Lombarda) was a medieval alliance formed in 1167, supported by the Pope, to counter the attempts by the Hohenstaufen Holy Roman Emperors to assert influence over the Kingdom of Italy as a part of the Holy Roman Empire. At its apex, it included most of the cities of Northern Italy, but its membership changed with time. With the death of the third and last Hohenstaufen emperor, Frederick II, in 1250, it became obsolete and was disbanded.

The association succeeded the Veronese League, established in 1164 by Verona, Padua, Vicenza, and the Republic of Venice, after Emperor Frederick I Barbarossa had claimed direct Imperial control over Italy at the 1158 Diet of Roncaglia and began to replace the Podestà magistrates by his own commissioners. It was backed by Pope Alexander III (the town of Alessandria was named in his honour), who also wished to see Frederick's power in Italy decline. Formed at Pontida on 1 December 1167, the Lombard League included—beside Verona, Padua, Vicenza and Venice—cities like Crema, Cremona, Mantua, Piacenza, Bergamo, Brescia, Milan, Genoa, Bologna, Modena, Reggio Emilia, Treviso, Vercelli, Lodi, Parma, Ferrara and even some lords, such as the Marquis Malaspina and Ezzelino da Romano.
