Piedmont (/ˈpiːdmɒnt/ PEED-mont; Italian: Piemonte [pjeˈmonte]; Piedmontese: Piemont [pjeˈmʊŋt]) is one of the 20 regions of Italy, located in the Northwest of the country. It borders the Liguria region to the south, the Lombardy and Emilia-Romagna regions to the east, and the Aosta Valley region to the northwest. Piedmont also borders Switzerland to the north and France to the west.

Piedmont has an area of 25,402 km (9,808 sq mi), making it the second-largest region of Italy after Sicily. It has 4,255,702 inhabitants as of 2025. The capital of Piedmont is Turin. This city was the first capital of the Kingdom of Italy, from 1861 to 1865.

German (Deutsch, pronounced [dɔʏtʃ] ) is a West Germanic language in the Indo-European language family, mainly spoken in Western and Central Europe. It is the majority and official (or co-official) language in Germany, Austria, Switzerland, and Liechtenstein. It is also an official language of Luxembourg, Belgium and the Italian autonomous province of South Tyrol, as well as a recognized national language in Namibia. There are also notable German-speaking communities in other parts of Europe, including: Poland (Upper Silesia), the Czech Republic (North Bohemia), Denmark (North Schleswig), Slovakia (Krahule), Romania, Hungary (Sopron), and France (Alsace). Overseas, sizeable communities of German-speakers are found in the Americas.

German is one of the major languages of the world, with nearly 80 million native speakers and over 130 million total speakers as of 2024. It is the most spoken native language within the European Union. German is the second-most widely spoken Germanic language, after English, both as a first and as a second language. German is also widely taught as a foreign language, especially in continental Europe (where it is the third most taught foreign language after English and French) and in the United States (where it is the third most commonly learned second language in K-12 education and among the most studied foreign languages in higher education after Spanish and French). Overall, German is the fourth most commonly learned second language globally. The language has been influential in the fields of philosophy, theology, science, and technology. It is the second most commonly used language in science and the third most widely used language on websites. The German-speaking countries are ranked fifth in terms of annual publication of new books, with one-tenth of all books (including e-books) in the world being published in German.

The Gallic Wars were waged between 58 and 50 BC by the Roman general Julius Caesar against the peoples of Gaul (present-day France, Belgium, and Switzerland). Gallic, Germanic, and Brittonic tribes fought to defend their homelands against an aggressive Roman campaign. The Wars culminated in the decisive Battle of Alesia in 52 BC, in which a complete Roman victory resulted in the expansion of the Roman Republic over the whole of Gaul. Though the collective Gallic armies were as strong as the Roman forces, the Gallic tribes' internal divisions eased victory for Caesar. Gallic chieftain Vercingetorix's attempt to unite the Gauls under a single banner came too late. Caesar portrayed the invasion as being a preemptive and defensive action, but historians agree that he fought the wars primarily to boost his political career and to pay off his debts. Still, Gaul was of significant military importance to the Romans. Native tribes in the region, both Gallic and Germanic, had attacked Rome several times. Conquering Gaul allowed Rome to secure the natural border of the river Rhine.

The wars began with conflict over the migration of the Helvetii in 58 BC, which drew in neighboring tribes and the Germanic Suebi. By 57 BC, Caesar had resolved to conquer all of Gaul. He led campaigns in the east, where the Nervii almost defeated him. In 56 BC, Caesar defeated the Veneti in a naval battle and took most of northwest Gaul. In 55 BC, Caesar sought to boost his public image. He undertook first-of-their-kind expeditions across the Rhine and the English Channel. Rome hailed Caesar as a hero upon his return from Britain, though he had achieved little beyond landing because his army had been too small. The next year, he returned with a larger army and reached much further inland; he extracted tribute from the locals and returned to Gaul. Tribes rose up on the continent, and the Romans suffered a humiliating defeat. 53 BC saw a brutal pacification campaign. That failed, and Vercingetorix led a revolt in 52 BC. Gallic forces won a notable victory at the Battle of Gergovia, but the Romans' indomitable siege works at the Battle of Alesia crushed the Gallic coalition.

A telephone number is the address of a telecommunication endpoint, such as a telephone, in a telephone network, such as the public switched telephone network (PSTN). A telephone number typically consists of a sequence of digits, but historically letters were also used in connection with telephone exchange names.

Telephone numbers facilitate the switching and routing of calls using a system of destination code routing. Telephone numbers are entered or dialed by a calling party on the originating telephone set, which transmits the sequence of digits in the process of signaling to a telephone exchange. The exchange completes the call either to another locally connected subscriber or via the PSTN to the called party. Telephone numbers are assigned within the framework of a national or regional telephone numbering plan to subscribers by telephone service operators, which may be commercial entities, state-controlled administrations, or other telecommunication industry associations.

The Burgundians (Latin: Burgundiones or less commonly Burgundii) were a Germanic people of the Roman imperial era, who established the powerful Kingdom of the Burgundians within the Roman empire, in what is now western Switzerland and south-eastern France. This kingdom is the source of much later names related to the region of Burgundy, including medieval entities such as the Duchy of Burgundy.

In earlier periods, peoples with the same name were reported by Roman sources to have lived in different parts of what is now Germany and Poland, and there are believed to be connections between at least some of these groups. For one thing, the kingdom's core group were followers of the Gibichung dynasty, who had previously led them as foederati in Roman territory on the Rhine border, probably near Worms in present day Germany. They left the Rhine after the Romans and their Hun allies killed many of the Burgundians along with their king Gundahar in 436, accusing them of rebellion. The death of Gundahar at the hands of the Huns became a central theme in medieval Germanic heroic legend, including the Nibelungenlied (where he is “Günther”) and the Völsunga saga (where he is “Gunnar”). After the remnants resettled in Sapaudia near Lake Geneva in about 443, their territory expanded to include Lyon as a new capital. The entire kingdom was incorporated into the Frankish empire in 534.

A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous.

The term top (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered subsummits (or subpeaks) of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. For summits that are permanently covered in significant layers of ice, the height may be measured by the highest point of rock (rock height) or the highest point of permanent solid ice (snow height).

The Blue Banana (Dutch: blauwe banaan; French: banane bleue; German: Blaue Banane; Italian: banana blu), also known as the European Megalopolis or the Liverpool–Milan Axis, is a discontinuous corridor of urbanization in Western and Central Europe, with a population of around 100 million. Over time, the region has been referred to by several names, each reflecting its development and significance. Initially, French geographer Roger Brunet, as the leader of RECLUS (Network for the study of changes in locations and spatial units), described the area as 'the European Backbone', which depicted an urban corridor extending from Liverpool to Milan.

Characterized by significant industrialization and urbanization, this area has attracted numerous public and private enterprises since the early post-war period, prompting researchers and academics to investigate the factors behind its remarkable development within Europe. It stretches approximately from North West England through the English Midlands across Greater London to the European Metropolis of Lille, the Benelux states with the Dutch Randstad and the Flemish Diamond and along the German Ruhrgebiet, Rhineland, Southern Germany, Alsace-Moselle in France in the west and Switzerland (Basel and Zürich), Austria (Vorarlberg and Tyrol) to Northern Italy (Milan, Turin, and Genoa) in the south.

Luxembourgish (/ˈlʌksəmbɜːrɡɪʃ/ LUK-səm-bur-ghish; also Luxemburgish, Luxembourgian, Letzebu(e)rgesch; endonym: Lëtzebuergesch [ˈlətsəbu̯əjəʃ] ) is a West Germanic language that is spoken mainly in Luxembourg. About 400,000 people speak Luxembourgish worldwide.

The language is standardized and officially the national language of the Grand Duchy of Luxembourg. As such, Luxembourgish is different from the German language also used in the Grand Duchy. The German language exists in a national standard variety of Luxembourg, which is slightly different from the standard varieties in Germany, Austria or Switzerland. Another important language of Luxembourg is French, which had a certain influence on both the national language, Luxembourgish, and the Luxembourg national variety of German. Luxembourgish, German and French are the three official languages (Amtssprachen) of Luxembourg.

Campione d'Italia (Italian: [kamˈpjoːne diˈtaːlja]; Comasco: Campiùn [kamˈpjuŋ]) is a comune (municipality) of the Province of Como in the Italian region of Lombardy. Located on the shores of Lake Lugano, it is an enclave surrounded by the Swiss canton of Ticino. At its closest, the enclave is less than one kilometre (0.6 mi) from the rest of Italy, but the intervening mountainous terrain requires a journey by road through the Swiss village of Bissone of over 14 km (9 mi) to reach the nearest Italian town, Lanzo d'Intelvi, and over 28 km (17 mi) to reach the city of Como. The comune's population was 1,748 in 2021.

The European single market, also known as the European internal market or the European common market, is the single market comprising mainly the 27 member states of the European Union (EU). With certain exceptions, it also comprises Iceland, Liechtenstein, Norway (through the Agreement on the European Economic Area), and Switzerland (through sectoral treaties). The single market seeks to guarantee the free movement of goods, capital, services, and people, known collectively as the four freedoms of the European Union. This is achieved through common rules and standards that all participating states are legally committed to follow.

Any potential EU accession candidates are required to make association agreements with the EU during the negotiation, which must be implemented prior to accession. In addition, through three individual agreements on a Deep and Comprehensive Free Trade Area (DCFTA) with the EU, Georgia, Moldova, and Ukraine have also been granted limited access to the single market in selected sectors. Turkey has access to the free movement of some goods via its membership in the European Union–Turkey Customs Union. The United Kingdom left the European single market on 31 December 2020. An agreement was reached between the UK Government and European Commission to align Northern Ireland on rules for goods with the European single market, to maintain an open border on the island of Ireland.
