The Battle of Parabiago was fought in February 1339 near Parabiago, in Lombardy, northern Italy, between the Milanese army and the St. George's (San Giorgio) Mercenaries of Lodrisio Visconti. A renowned condottiero, the latter was an exiled member of the Visconti family then in power in Milan with a kind of triumvirate formed by Azzone and his uncles, Luchino and archbishop Giovanni Visconti, all Lodrisio's brothers. Aiming to return victoriously to his city, he hired some 2,500 knights, mainly from Germany, and 1,000 Swiss infantry which had fought in the unsuccessful war of Mastino II della Scala for the hegemony in northern Italy. These units were led by Werner von Urslingen and Konrad von Landau.
