In the Middle Ages, the city was the location of the Battle of Legnano in which Emperor Frederick I was defeated by the Lombard League (1176). Because of the historic victory of the Lombard League over Frederick Barbarossa, it is the only town other than Rome named in the Italian national anthem ("[...] "Dall'Alpi a Sicilia dovunque è Legnano" [...]", en. "From the Alps to Sicily, Legnano is everywhere"). Every year the people of Legnano commemorate the battle with Palio di Legnano. In the institutional sphere, on 29 May, the date of the battle of Legnano, it was chosen as the regional holiday of Lombardy.
