Thurgau

Thurgau, anglicized as Thurgovia and formally the Canton of Thurgau, is one of the 26 cantons forming the Swiss Confederation. It is made up of five districts, its capital is Frauenfeld, and it is part of Eastern Switzerland. The canton is named after the river Thur, and the name Thurgovia was historically used for a larger area that included part of the river basin upstream of the modern canton. The cantons of the Old Swiss Confederacy took the land from the Habsburgs and held it as subject territory from the middle of the fifteenth century. Thurgau was first declared a canton in its own right in 1798 with the formation of the Helvetic Republic, and in 1803 it became a member of the Swiss confederation under the Act of Mediation. It had about 302,800 residents at the end of 2025.
