Ottone Visconti
Quick Summary
Ottone Visconti was the archbishop of Milan who played a crucial role in the rise of the powerful Visconti family. In 1262, Pope Urban IV appointed him to counterbalance the influence of the Della Torre family. Ottone defeated the Della Torre family at the Battle of Desio in 1277, reclaiming the temporal powers of the archbishopric and transferring authority to his grandnephew, Matteo I Visconti. Matteo I Visconti, with Ottone's support, became captain of the people and eventually lord of Milan, establishing the Visconti dynasty's rule over the city and expanding their control over numerous north Italian cities. This period marked the beginning of the signoria in Milan, where a single lord governed.123
