Vaud in the context of "Lake Neuchâtel"

Romandy (French: Romandie or Suisse romande; Arpitan: Romandia) is the French-speaking historical and cultural region of Switzerland. In 2020, about 2 million people, or 22.8% of the Swiss population, lived in Romandy. The majority of the romand population lives in the western part of the country, especially the Arc Lémanique region along Lake Geneva, connecting Geneva, Vaud, and the Lower Valais.

French is the sole official language in four Swiss cantons: Geneva, Vaud, Neuchâtel, and Jura. Additionally, French and German have co-official status in three cantons: Fribourg/Freiburg, Valais/Wallis, and Berne/Bern.

Lausanne (/loʊˈzæn/ loh-ZAN, US also /loʊˈzɑːn/ loh-ZAHN; French: [lozan] ; Arpitan: Losena [lɔˈzəna] ) is the capital and largest city of the Swiss French-speaking canton of Vaud, in Switzerland. The Olympic capital, it is a hilly city situated on the shores of Lake Geneva, about halfway between the Jura Mountains and the Alps, and facing the French town of Évian-les-Bains across the lake. Lausanne is located (as the crow flies) 51.7 kilometres (32 miles) northeast of Geneva, the nearest major city. The Federal Supreme Court of Switzerland convenes in Lausanne, although it is not the de jure capital of the nation.

The municipality of Lausanne has a population of about 150,000, making it the fourth largest city in Switzerland after Basel, Geneva, and Zurich, with the entire agglomeration area having about 420,000 inhabitants (as of January 2019). The metropolitan area of Lausanne-Geneva (including Vevey-Montreux, Yverdon-les-Bains, Valais and foreign parts), commonly designated as Arc lémanique was over 1.3 million inhabitants in 2017 and is the fastest growing in Switzerland.

Lake Geneva is a deep lake on the north side of the Alps, shared between Switzerland and France. It is one of the largest lakes in Western Europe and the largest on the course of the Rhône. Sixty percent (345.31 km or 133.32 sq mi) of the lake belongs to Switzerland (the cantons of Vaud, Geneva and Valais) and forty percent (234.71 km or 90.62 sq mi) to France (the department of Haute-Savoie).

Valais (UK: /ˈvæleɪ/ VAL-ay, US: /væˈleɪ/ val-AY; French: [valɛ] ), more formally, the Canton of Valais or Wallis, is one of the 26 cantons forming the Swiss Confederation. It is composed of thirteen districts and its capital and largest city is Sion.

Valais is situated in the southwestern part of the country. It borders the cantons of Vaud and Bern to the north, the cantons of Uri and Ticino to the east, as well as Italy to the south and France to the west. It is one of the three large southern Alpine cantons, along with Ticino and Grisons. It is a bilingual canton, French and German being its two official languages. Traditionally, the canton is divided into Lower, Central, and Upper Valais, the latter region constituting the German-speaking minority.

The Canton of Geneva, officially the Republic and Canton of Geneva, is one of the 26 cantons of the Swiss Confederation. It is composed of forty-five municipalities, and the seat of the government and parliament is in the city of Geneva.

Geneva is the French-speaking westernmost canton of Switzerland. It lies at the western end of Lake Geneva and on both sides of the Rhone, its main river. Within the country, the canton borders Vaud to the east, the only adjacent canton. However, most of Geneva's border is with France, specifically the region of Auvergne-Rhône-Alpes. As is the case in several other Swiss cantons (Ticino, Neuchâtel, and Jura), Geneva is referred to as a republic within the Swiss Confederation.

The Lake Geneva region is the region of Switzerland encompassing the cantons of Geneva, Vaud and Valais. It is one of the NUTS-2 regions of Switzerland.

The Lemanic Arc (French: Arc lémanique) is the region on the north side of Lake Léman, stretching out from Geneva to Lausanne and Montreux. Its parts are Geneva, La Côte, Lausanne, Lavaux, La Riviera and le Chablais.

The canton of Bern or Berne is one of the 26 cantons forming the Swiss Confederation. Its capital city, Bern, is also the de facto capital of Switzerland. The bear is the heraldic symbol of the canton, displayed on a red-yellow background.

Comprising ten districts, Bern is the second-largest canton by both surface area and population. Located in west-central Switzerland, it is surrounded by eleven cantons. It borders the cantons of Jura and Solothurn to the north. To the west lie the cantons of Neuchâtel, Fribourg, and Vaud. To the south lies the cantons of Valais. East of the canton of Bern lie the cantons of Uri, Nidwalden, Obwalden, Lucerne and Aargau. The geography of the canton includes a large share of all three natural regions of Switzerland: the Jura Mountains (the Bernese Jura), the Swiss Plateau (the Bernese Mittelland) and the Alps (the Bernese Oberland).

During the French Revolutionary Wars, the revolutionary armies marched eastward, enveloping Switzerland in their battles against Austria. In 1798, Switzerland was completely overrun by the French and was renamed the Helvetic Republic. The Helvetic Republic encountered severe economic and political problems. In 1798 the country became a battlefield of the Revolutionary Wars, culminating in the Battles of Zürich in 1799.

In 1803 Napoleon's Act of Mediation reestablished a Swiss Confederation that partially restored the sovereignty of the cantons, and the former tributary and allied territories of Aargau, Thurgau, Graubünden, St. Gallen, Vaud and Ticino became cantons with equal rights.
