History of the canton of Valais

From prehistory to the Roman province

The oldest human traces in Valais, about 35'000 years old, were found in the Tanay area above Vouvry, at 1'800 metres. In Sion, the Petit-Chasseur necropolis, with its dolmens from the early 3rd millennium BC and its human-shaped stelae, is one of the high points of European prehistory.

Four Celtic peoples lived in the valley: the Nantuates, Veragri, Seduni and Uberi. After the campaign of Drusus and Tiberius in 16-15 BC, the upper Rhône came under Roman control. Under the emperor Claudius (41-54) Valais became a province of its own, and Forum Claudii Vallensium (Martigny) was founded next to the Celtic settlement of Octodurus.

Saint-Maurice and the prince-bishops of Sion

Around 380 Theodore (Saint Theodulus) established the cult of Saint Maurice at Agaunum, where the Burgundian king Sigismund founded the abbey of Saint-Maurice in 515. The bishop's seat moved to Sion between 565 and 585. In 999 King Rudolph III of Burgundy gave the county of Valais to the bishop of Sion.

The dizains (districts) appeared in the 14th century. In 1475, under Bishop Walter Supersaxo, the Valaisans defeated the Savoyard army at the Planta in Sion and took the Lower Valais. Monthey and Saint-Maurice remained subject lands until 1798.

From the Revolution to the twentieth canton

In February 1798 the Diet granted freedom and independence to the Lower Valais, and Valais was then incorporated into the Helvetic Republic. It was an independent republic from 1802 to 1810, then the French département of Simplon until December 1813.

After the constitution of 12 May 1815, the Act of Union of 4 August 1815 made Valais the twentieth canton of the Confederation. The canton has two official languages, French and German, and the language border runs through the Finges forest.

Valais today

On 14 July 1865 a rope team led by Edward Whymper reached the summit of the Matterhorn; four men died on the descent. The mountain made Zermatt one of the most famous tourist places in Switzerland.

The population grew from 81'559 in 1850 to 206'563 in 1970 and 272'399 in 2000. At the end of 2025 Valais had 376'113 inhabitants. Its capital is Sion.
