The Walser people are named after the Wallis (Valais), the uppermost Rhône valley, where they settled from roughly the 10th century in the late phase of the migration of the Alamanni, crossing from the Bernese Oberland; because of linguistic differences among the Walser dialects, it is supposed that there were two independent immigration routes.
From the upper Wallis, they began to spread south, west and east between the 12th and 13th centuries, in the so-called Walser migrations (Walserwanderungen).
These are: Simplon, in Canton of Valais; Bosco/Gurin, in Canton of Ticino; and the following communities in Graubünden (Grisons): Obersaxen; Valsertal (Vals, St. Martin); Safiental (Valendas, Versam, Tenna, Safien); Rheinwald (Medels, Nufenen, Splügen, Sufers, Hinterrhein, Avers); Schanfigg (Arosa, Langwies); Albula (Mutten, Schmitten, Wiesen); Landquart (Davos, Klosters, Furna, Says, St. Antönien, Valzeina).
Wartau, (Matug, Walserberg, Palfris) and Walser speaking people may live in the canton of Geneva.
Until the 1930s, the dialects of Walser German and Romandy based on the French language was still spoken among a few hundred residents.
[citation needed] In Austria, there are 14 Walser communities: Grosses Walsertal (Blons, Fontanella, Raggal, St. Gerold, Sonntag, Thüringerberg), Kleinwalsertal (Mittelberg, a practical enclave of Germany), Brandnertal (Brand), Montafon (Silbertal), Reintal (Laterns), Tannberg (Schröcken, Lech, Warth), all in Vorarlberg; and in Paznauntal (Galtür), in Tyrol.
