History of Valais
aspect of Swiss history
Occupied since prehistoric times, the canton of Valais saw the rise of an exceptional civilization during the Bronze Age. From the 4th century BC, four Celtic tribes shared its territory, which was incorporated into the Roman Empire by Augustus. The Gallo-Roman Valais, located on the important Great St Bernard Pass, was prosperous. Christianity was first established in 377, and a bishopric was opened in Martigny by 381 at the latest.
With the fall of the Empire, the region became Burgundian, before being integrated into the Carolingian Frankish kingdom. On its demise, it became part of the Transjurane kingdom of Burgundy, of which the abbey of Saint-Maurice d'Agaune was the religious center. The county of Valais became the property of the bishop in 999, upon donation by Rudolph III of Burgundy. In the 11th century, it passed to the Holy Roman Empire, and feudalism fragmented it into numerous seigneuries and territories. The upper part of the territory became Germanized in successive waves between the 9th and 14th centuries, while the influence of the Counts, then Dukes, of Savoy increased in the Lower Valais. At the end of the 14th century, it became an ally of the Swiss cantons, and its border was fixed at the Morge de Conthey.

Why this record matters
The phrase “aspect of Swiss history” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q776635. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
