Switzerland, officially the Swiss Confederation, is a mountainous West Central European country.  It is a landlocked country that occupies the crossroads of Germanic and Romance Europe, as reflected in its four main linguistic and cultural regions: German, French, Italian and Romansh.  Switzerland is a federal republic composed of 26 cantons, with federal authorities based in Bern.   Switzerland is bordered by Italy to the south, France to the west, Germany to the north and Austria and Liechtenstein to the east.  Although the Alps occupy the greater part of the territory, the Swiss population of approximately 8.5 million is concentrated mostly on the plateau, where the largest cities and economic centers are, among them Zürich, Geneva, Basel and Lausanne.

The Federal Constitution adopted in 1848 is the legal foundation of the modern federal state. A new Swiss Constitution was adopted in 1999, but did not introduce notable changes to the federal structure. It outlines basic and political rights of individuals and citizen participation in public affairs, divides the powers between the Confederation and the cantons and defines federal jurisdiction and authority. There are three main governing bodies on the federal level: the bicameral parliament (legislative), the Federal Council (executive) and the Federal Court (judicial).
