Biography
Gian Galeazzo Visconti was the supreme political operator of late medieval Italy, a man whose ambition was to forge a kingdom from the patchwork of northern city-states. Inheriting the lordship of Pavia as a young man, he initially ruled Lombardy alongside his bellicose uncle, Bernabò. In 1385, he executed a masterstroke of treachery, inviting his uncle to a religious festival only to have him arrested and imprisoned, seizing sole power. From there, he embarked on a relentless campaign of conquest, swallowing Verona, Vicenza, Padua, Siena, and Pisa, often through bribery and strategic marriages as much as military force. His court at Pavia became a center of learning and art, funding the magnificent Certosa di Pavia monastery and pushing forward the construction of Milan's soaring cathedral. His death from fever in 1402, just as he seemed poised to take Florence and perhaps a royal crown, abruptly ended the dream of a unified northern Italian realm, leaving a legacy of both breathtaking cultural patronage and chilling realpolitik.
