Ambrosian Republic in Depth

History

When Filippo Maria Visconti, Duke of Milan, died on 13 August 1447, the city was thrown into confusion by his unexpected demise and the speed with which claimants to his title acted. Filippo Maria had no heir through male bloodlines and therefore a succession crisis occurred.

Francesco Sforza, a famous condottiero and Filippo Maria's son-in-law through his illegitimate daughter Bianca Maria Visconti.

The two most prominent candidates supported by the Milanese population were however Alfonso of Aragon and Francesco Sforza.

The Bracceschi family, supporters of the King of Aragon, seized the city on the 13th, the night of Duke Filippo Maria's death, forcing the captains to swear allegiance to Alfonso. However, other influential citizens believed that a republic could be proclaimed.
