Marco I Visconti

Marco Visconti, nicknamed Balatrone (c. 1289–1329), was a Ghibelline condottiero and son of Matteo I Visconti. He fought for Henry VII from 1310, taking Alessandria and ousting Archbishop Cassone della Torre from Milan; he later served noble factions in Genoa and was excommunicated.

He fought for Pisa at Montecatini in 1315. In 1327, with Lodrisio, he accused Galeazzo of treason and established a pro-imperial government.

In Tuscany in 1329 he seized Lucca with the Company of the Ceruglio and sold it for thirty thousand florins. On his return to Milan on 5 September 1329, he was strangled and his body thrown from a window; his nephew Azzone and Luchino were said to have taken part.
