Overview
Galeazzo da Sanseverino (French: Galéas de Saint-Séverin'), known as the son of Fortuna, (c. 1460 – 24 February 1525) was an Italian-French condottiere and Grand Écuyer de France; Marquis of Bobbio, Count of Caiazzo, Castel San Giovanni, Val Tidone and Voghera. He was first the favorite of Ludovico il Moro and Beatrice d'Este, then of Louis XII and Francis I of France, as well as a sworn enemy of Gian Giacomo Trivulzio.
Life
He was the third son of the famous leader Roberto Sanseverino, first Count of Caiazzo and Giovanna da Correggio. The date of birth is not at all clear, to be placed around 1458-60 and perhaps in Milan, where his mother Giovanna was certainly in the years 1458-59, waiting for the return of her husband from his pilgrimage to the Holy Land. It is not even known whether his brother Antonio Maria was born before or after, but certainly after his second son Gaspare, known as Fracasso, who was already married in 1475.
He made his first military experiences in the company of his father Roberto and in 1475 he obtained, together with his brothers, his first conduct in the pay of Florence.
At the service of Milan
In June 1483, during the Salt War, Galeazzo and his brother deserted the Venetian conduct of their father Roberto and entered the service of the Duke of Bari, then Duke of Milan, Ludovico il Moro, despite the fact that his father was his bitter enemy. Shortly afterwards two of his half-brothers, Giorgio known as Faccenda and Ottaviano, also followed them. Two other brothers, and , remained faithful to their father, and only after Roberto's death, in 1489, they passed to Moro. The latter essentially gained in his service all the sons of the great enemy, esteemed among the best leaders of the peninsula.
