Battle on the Planta

The Battle on the Planta, fought on 13 November 1475 around Conthey near Sion, Valais, Switzerland, was part of the Burgundian Wars.

In the 13th and 14th centuries, the Upper Valais was colonized by Germans from Hasli in the Canton of Bern. The Upper Valais was loosely allied with the Swiss, especially with Bern. The Lower Valais were inhabited by French speakers under the power of the Dukes of Savoy. During the early and mid 15th century conflicts between the Upper Valais and Lower Valais often led to fighting. In 1446 Bern and Savoy signed a peace treaty, though border conflicts over the following decades damaged the agreement. In 1473 Duchess Yolande of Savoy embargoed Bern.
