Switzerland, officially the Swiss Confederation, is a landlocked country located at the intersection of Central, Western, and Southern Europe. It is bordered by Germany to the north, France to the west, Austria and Liechtenstein to the east, and Italy to the south. Switzerland is geographically divided among the Swiss Alps, the Swiss Plateau, and the Jura Mountains; the Alps cover most of the country's territory, whereas the majority of its 9 million people are concentrated on the plateau, which hosts many of the largest cities and economic centres, including Zurich, Geneva, Basel, Bern, Lausanne, Winterthur, and Lucerne.
Switzerland is a federal republic composed of 26 cantons, with Bern serving as the federal city and the seat of the national government. The country encompasses four principal linguistic and cultural regions—German, French, Italian, and Romansh—reflecting a long-standing tradition of multilingualism and cultural pluralism. Swiss national identity nonetheless remains fairly cohesive, rooted in a shared historical background, common values such as federalism and direct democracy, and Alpine symbolism. Swiss nationhood transcends language, ethnicity, and religion, leading to Switzerland being described as a Willensnation ("nation of volition") rather than a conventional nation state.
The country originates from the Old Swiss Confederacy established in the Late Middle Ages as a defensive and commercial alliance; the Federal Charter of 1291 is considered the country's founding document. The confederation steadily expanded and consolidated despite external threats and internal political and religious strife. Swiss independence from the Holy Roman Empire was formally recognized in the Peace of Westphalia in 1648. The confederation was among the first and few republics of the early modern period, and the only one besides San Marino to survive the Napoleonic Wars. Switzerland remained a network of self-governing states until 1798, when revolutionary France invaded and imposed the centralist Helvetic Republic. Napoleon abolished the republic in 1803 and reinstated a confederation. Following the Napoleonic Wars, Switzerland restored its pre-revolutionary system, but by 1830 faced growing division and conflict between liberal and conservative movements; this culminated in a new constitution in 1848 that established the current federal system and enshrined principles such as individual rights, separation of powers, and parliamentary bicameralism.
Switzerland has maintained a policy of armed neutrality since the 16th century and has not fought an international war since 1815. It joined the Council of Europe in 1964 and the United Nations (UN) in 2002, pursuing an active foreign policy that includes frequent involvement in peace building and global governance. Switzerland is the birthplace of the Red Cross and hosts the headquarters or offices of most major international institutions, including the WTO, the WHO, the ILO, FIFA, the WEF, and the UN. It is a founding member of the European Free Trade Association (EFTA) and participates in the European single market and the Schengen Area. Switzerland is among the world's most developed countries, with the highest nominal wealth per adult and the eighth-highest gross domestic product (GDP) per capita. It performs highly on several international metrics, including economic competitiveness, democratic governance, and press freedom. Zurich, Geneva and Basel rank among the highest in quality of life, albeit with some of the highest costs of living. Switzerland has a longstanding banking and financial sector, advanced pharmaceutical and biotechnology industries, and a strong tradition of watchmaking, precision engineering, and technology. It is known for its chocolate and cheese production, well-developed tourism industry, and growing startup sector.
The English name Switzerland compounds Switzer, an obsolete term for a Swiss person which was in use during the 16th to 19th centuries, with the common English suffix -land denoting a region or country. The English adjective Swiss is a loanword from French Suisse, also in use since the 16th century. The name Switzer is from the Alemannic Schwiizer, in origin an inhabitant of Schwyz and its associated territory, one of the Waldstätte cantons which formed the nucleus of the Old Swiss Confederacy. The Swiss began to adopt the name for themselves after the Swabian War of 1499, used alongside the term for "Confederates", Eidgenossen (literally: comrades by oath), used since the 14th century. The ISO 3166-1 data codes for Switzerland, CH and CHE, are derived from Latin Confoederatio Helvetica (Helvetic Confederation).
The toponym Schwyz itself was first attested in 972, as Old High German Suittes, perhaps related to swedan 'to burn' (cf. Old Norse svíða 'to singe, burn'), referring to the area of forest that was burned and cleared to build. The name was extended to the area dominated by the canton, and after the Swabian War of 1499 gradually came to be used for the entire Confederation. The Swiss German name of the country, Schwiiz, is homophonous to that of the canton and the settlement, but distinguished by the use of the definite article (d'Schwiiz for the Confederation, but simply Schwyz for the canton and the town). The long [iː] of Swiss German is historically and still often today spelled ⟨y⟩ rather than ⟨ii⟩, preserving the original identity of the two names even in writing.
The Latin name Confoederatio Helvetica was neologised and introduced gradually after the formation of the federal state in 1848, harking back to the Napoleonic Helvetic Republic. It appeared on coins from 1879, inscribed on the Federal Palace in 1902 and after 1948 used in the official seal (e.g., the ISO banking code "CHF" for the Swiss franc, the Swiss postage stamps ('HELVETIA') and the country top-level domain ".ch", are both taken from the state's Latin name). The name Helvetica is derived from the Helvetii, a Gaulish tribe living on the Swiss Plateau before the Roman era. It in turn, gives its name to a typeface developed in 1960.
Helvetia appeared as a national personification of the Swiss confederacy in the 17th century in a 1672 play by Johann Caspar Weissenbach.
The state of Switzerland took its present form with the adoption of the Swiss Federal Constitution in 1848. Switzerland's precursors established a defensive alliance in 1291, forming a loose confederation that persisted for centuries.
The oldest traces of hominid existence in Switzerland date to about 150,000 years ago. The oldest known farming settlements in Switzerland, which were found at Gächlingen, date to around 5300 BC.
The earliest known tribes formed the Hallstatt and La Tène cultures, named after the archaeological site of La Tène on the north side of Lake Neuchâtel. La Tène culture developed and flourished during the late Iron Age from around 450 BC, possibly influenced by Greek and Etruscan civilisations. One of the most prominent La Tène tribes were the Helvetii, who primarily occupied the Swiss Plateau, alongside the Rhaetians in the eastern regions. Facing pressures from Germanic tribes, in 58 BC, the Helvetii, influenced by Orgetorix, a wealthy aristocrat, decided to abandon the Swiss Plateau for better opportunities in western Gallia. After Orgetorix's mysterious death, the tribe continued their migration but was decisively defeated by Julius Caesar's armies at the Battle of Bibracte, in present-day eastern France. Following their defeat, the Helvetii were forced by Caesar to return to their original lands, where they were subjected to stringent restrictions on their autonomy and movements. In 15 BC, Tiberius (later the second Roman emperor) and his brother Drusus conquered the Alps, integrating them into the Roman Empire. The area occupied by the Helvetii first became part of Rome's Gallia Belgica province and then of its Germania Superior province. The eastern portion of modern Switzerland was integrated into the Roman province of Raetia. Sometime around the start of the Common Era, the Romans maintained a large camp called Vindonissa, now a ruin at the confluence of the Aare and Reuss rivers, near the town of Windisch.
