The Golden Ambrosian Republic (Lombard: Aurea Republega Ambrosiana; Italian: Aurea Repubblica Ambrosiana; 1447–1450) was a short-lived republic founded in Milan by members of the University of Pavia with popular support, during the first phase of the Milanese War of Succession. With the aid of Francesco Sforza they held out against the forces of the Republic of Venice, but after a betrayal Sforza defected and captured Milan to become Duke himself, abolishing the Republic.
