The first, Muzzio Attendo
The first, Muzzio Attendolo, a native of Cottignola, served under the Angevin kings of Naples, was the most successful condottiere of his time, and took a name meaning "strong". His son took over rulership of their city from the extinct Visconti family. They eventually joined with the Borgias after the marriage of the infamous Lucrezia to Giovanni, the bastard son of Costanzo. Rulers from this family, noted for mental instability and despotism, included Gian Galeazzo, Ludovico "il Moro", who employed Leonardo da Vinci, and Francesco. For ten points, name this ducal family of Milan.
