Canton of Solothurn in the context of "Solothurn"

The Republic and Canton of Jura (officially in French: République et Canton du Jura), less formally the Canton of Jura or Canton Jura (/ˈ(d)ʒʊərə/ JOOR-ə, ZHOOR-ə; French: [ʒyʁa] ), is the newest (founded in 1979) of the 26 Swiss cantons, located in the northwestern part of Switzerland. The capital is Delémont. It shares borders with the canton of Basel-Landschaft, the canton of Bern, the canton of Neuchatel, the canton of Solothurn, and the French regions of Bourgogne-Franche-Comté and Grand Est.

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).

The Sonderbund War (German: Sonderbundskrieg, French: Guerre du Sonderbund, Italian: Guerra del Sonderbund) of November 1847 was a civil war in Switzerland, then still a relatively loose confederacy of cantons. It ensued after seven Catholic cantons formed the Sonderbund ("separate alliance") in 1845 to protect their interests against a centralization of power. The war concluded with the defeat of the Sonderbund. It resulted in the emergence of Switzerland as a federal state, concluding the period of political "restoration and regeneration" in Switzerland.

The Sonderbund consisted of the cantons of Lucerne, Fribourg, Valais, Uri, Schwyz, Unterwalden and Zug, all predominantly Catholic and governed by conservative administrations. The cantons of Ticino and Solothurn, also predominantly Catholic but governed by liberal administrations, did not join the alliance.

The European Metropolitan Region of Zurich (EMRZ), also Greater Zurich Area (GZA, German Zürcher Wirtschaftsraum, Metropolregion Zürich), the metropolitan area surrounding Zurich, is one of Europe’s economically strongest areas and Switzerland’s economic centre. It comprises the area that can be reached within a roughly 80-minute drive from Zurich Airport. Home to many international companies, it includes most of the canton of Zurich, and stretches as far as the Aargau and Solothurn in the west, Thurgau, St. Gallen and parts of Grisons in the east, Schaffhausen in the north and Zug and parts of Schwyz and Glarus in the south.

The Swiss federal office for statistics defines an unofficial metropolitan area as including all areas where more than 1/12 of the workforce commutes to the core area.According to the 2000 Swiss census, this includes a total of 220 municipalities in seven cantons: 127 in the canton of Zürich, 58 in Aargau, 11 in Schwyz, 10 in Zug, 9 in Schaffhausen, 3 in Thurgau and 2 in St. Gallen.

Canton of Basel-Landschaft or Basel-Country, informally known as Baselland or Baselbiet (/ˌbɑːzəl ˈlændʃɑːft/; German: Kanton Basel-Landschaft [ˈkantɔn ˌbaːzl̩ ˈlantʃaft] ; Romansh: Chantun Basilea-Champagna; French: Canton de Bâle-Campagne [bɑl.kɑ̃.paɲ]; Italian: Canton Basilea Campagna), is one of the 26 cantons forming the Swiss Confederation. It is composed of five districts and its capital city is Liestal. It is traditionally considered a "half-canton", the other half being Basel-Stadt, its urban counterpart.

Basel-Landschaft is one of the northernmost cantons of Switzerland. It lies essentially south of the Rhine and north of the Jura Mountains. The canton shares borders with the canton of Basel-Stadt to the north, the canton of Aargau to the east, the canton of Solothurn to the south and the canton of Jura to the west. It shares international borders as well with France and Germany to the north.

The Prince-Bishopric of Basel (German: Hochstift Basel, Fürstbistum Basel, Bistum Basel) was an ecclesiastical principality within the Holy Roman Empire, ruled from 1032 by prince-bishops with their seat at Basel, and from 1528 until 1792 at Porrentruy, and thereafter at Schliengen. As an imperial estate, the prince-bishop had a seat and voting rights at the Imperial Diet. The final dissolution of the state occurred in 1803 as part of the German Mediatisation.

The Prince-Bishopric comprised territories now in the Swiss cantons of Basel-Landschaft, Jura, Solothurn and Bern, besides minor territories in nearby portions of southern Germany and eastern France. The city of Basel ceased to be part of the Prince-Bishopric after it joined the Swiss Confederacy in 1501.
