Switzerland, officially the Swiss Confederation, is a country situated in western, central and southern Europe. It consists of 26 cantons, and the city of Bern is the seat of the federal authorities. The sovereign state is a federal republic bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is a landlocked country geographically divided between the Alps, the Swiss Plateau and the Jura, spanning a total area of 41285 km2 (land area 39997 km2). While the Alps occupy the greater part of the territory, the Swiss population of approximately 8.5 million people is concentrated mostly on the plateau, where the largest cities are to be found: among them are the two global cities and economic centres Zürich and Geneva.
The establishment of the Old Swiss Confederacy dates to the late medieval period, resulting from a series of military successes against Austria and Burgundy. Swiss independence from the Holy Roman Empire was formally recognized in the Peace of Westphalia in 1648. The country has a history of armed neutrality going back to the Reformation; it has not been in a state of war internationally since 1815 and did not join the United Nations until 2002. Nevertheless, it pursues an active foreign policy and is frequently involved in peace-building processes around the world. In addition to being the birthplace of the Red Cross, Switzerland is home to numerous international organisations, including the second largest UN office. On the European level, it is a founding member of the European Free Trade Association, but notably not part of the European Union, the European Economic Area or the Eurozone. However, it participates in the Schengen Area and the European Single Market through bilateral treaties.
