Galeazzo Maria Sforza

Galeazzo Maria Sforza (January 24, 1444–December 26, 1476) was Duke of Milan. He was a member of the Sforza family of Milanese rulers, famous as patrons of the arts and music. He was also famous for being lustful, cruel and tyrannical.

Galeazzo was born to Francesco Sforza and Bianca Maria Visconti. He married into the Gonzaga family, and on the death of his wife Dorotea married again, to another Gonzaga, the daughter of Lodovico I of Mantua. Galeazzo was murdered on December 26, 1476, on the steps of Milan cathedral, by a group of three noblemen where were evidently attempting to re-stage the murder of Julius Caesar.

Galeazzo was famous as a patron of music. Under his direction, financial backing and encouragement, his chapel grew into one of the most famous and historically significant musical ensembles in Europe. Composers from the north, especially the Franco-Flemish composers from the present-day Low Countries, came to sing in his chapel and write masses, motets and secular music for him. Some of the figures associated with the Sforza chapel include Alexander Agricola, Johannes Martini, Loyset Compère, Gaspar van Weerbeke, and most famously, Josquin Des Prez, who was to become the most famous composer in Europe.

On Galeazzo's death, his son Gian Galeazzo Sforza became Duke.

In 1493 Galeazzo's daughter Bianca Maria Sforza (1472-1510/11) was married to emperor Maximilian I and thus she became empress of the Holy Roman Empire.
