Galeazzo I Visconti
Galeazzo I Visconti (1277–1328), son of Matteo I Visconti, married Beatrice d'Este on 24 June 1300 and shared the long Visconti exile. Named capitano del popolo of Milan in 1322, he succeeded his father as lord and defeated a Papal–Angevin army at Bassignana, earning excommunication from Pope John XXII in March 1323.
With Emperor Louis IV he routed another papal army near Monza, but the emperor imprisoned him there in 1327 on his brother Marco's accusations. Freed in March 1328, he took shelter with Castruccio Castracani and died at Pescia on 6 August; his son Azzone succeeded him.
