user: What are the four main linguistic and cultural regions of Switzerland?

assistant: <think>
Switzerland originates from the Old Swiss Confederacy established in the Late Middle Ages, following a series of military successes against Austria and Burgundy; the Federal Charter of 1291 is considered the country's founding document. Swiss independence from the Holy Roman Empire was formally recognised in the Peace of Westphalia in 1648. Switzerland has maintained a policy of armed neutrality since the 16th century and has not fought an international war since 1815. It joined the United Nations only in 2002, but pursues an active foreign policy that include frequent involvement in peace-building processes worldwide.

Switzerland is the birthplace of the Red Cross, one of the world's oldest and best-known humanitarian organisations, and hosts the headquarters or offices of most major international institutions, including the WTO, the WHO, the ILO, FIFA, and the United Nations. It is a founding member of the European Free Trade Association (EFTA), but not part of the European Union (EU), the European Economic Area, or the Eurozone; however, it participates in the European single market and the Schengen Area through bilateral treaties. Switzerland is a federal republic composed of 26 cantons, with federal authorities based in Bern.

It has four main linguistic and cultural regions: German, French, Italian and Romansh. Although most Swiss are German-speaking, national identity is fairly cohesive, being rooted in a common historical background, shared values such as federalism and direct democracy, and Alpine symbolism. Swiss identity transcends language, ethnicity, and religion, leading to Switzerland being described as a Willensnation ("nation of volition") rather than a nation state.</think>
