The 26 cantons of Switzerland are the member states of the Swiss Confederation. The nucleus of the Swiss Confederacy in the form of the first three confederate allies used to be referred to as the Waldstätte. Two important periods in the development of the Old Swiss Confederacy are summarized by the terms Acht Orte ('Eight Cantons'; from 1353 to 1481) and Dreizehn Orte ('Thirteen Cantons', from 1513 to 1798).
Each canton of the Old Swiss Confederacy, formerly also Ort ('lieu/locality', from before 1450), or Stand ('estate', from c. 1550), was a fully sovereign state with its own border controls, army, and currency from at least the Treaty of Westphalia (1648) until the establishment of the Swiss federal state in 1848, with a brief period of centralised government during the Helvetic Republic (1798–1803). The term Kanton has been widely used since the 19th century.
