Overview

Biography
Visconti was born in Abbiategrasso. Following his father's death, he assumed the title of duke at the age of thirteen, under his mother's regency. The Duchy of Milan soon disintegrated: among the various parties contending its lands, the condottiero Facino Cane prevailed.
Taking advantage of Gian Maria's cruelty, he managed to create in him doubts about Caterina, who was imprisoned in Monza, where she died on 17 October 1404, probably murdered. The duke was famous for his dogs, which were trained to slaughter men.
