Three Leagues
The Three Leagues were normally allied with the Old Swiss Confederacy. Initially this was a response to the expansion of the Habsburgs. The Musso war against the Duchy of Milan in 1520 pushed the League closer to the Swiss Confederacy. The League would remain an associate to the Swiss until the Napoleonic Wars, when it was absorbed into the Helvetic Republic. After the Napoleonic Act of Mediation, the Three Leagues became the canton of Graubünden.
