Вацлав IV
Gian Galeazzo and Caterina had two sons: Giovanni Maria in 1388 and Filippo Maria in 1392. In 1395 Gian Galeazzo obtained from the Emperor Wenceslaus IV of Bohemia, for the price of 100,000 florins, the title of Duke of Milan. During the years of his rule, the Visconti domains reached the greatest territorial extension in northern and central Italy. Of all the domains of the previous years only Genoa, ruled by the archbishop Giovanni, remained excluded. After a short disease, the plague or the gout, Gian Galeazzo died on 3 September 1402.
