Thurgau

The Canton of Thurgau (German:  Thurgau , anglicized as Thurgovia) is a northeast canton of Switzerland.

It is named for the Thur River, and the name Thurgovia was historically used for a larger area, including part of this river's basin upstream of the modern canton. The area of what is now Thurgau was acquired as subject territories by the cantons of the Old Swiss Confederacy from the mid 15th century. Thurgau was first declared a canton in its own right at the formation of the Helvetic Republic in 1798.

The population, as of December 2014, is 263,733. In 2007, there were a total of 47,390 (or 19.9% of the population) who were resident foreigners. The capital is Frauenfeld.

History

In prehistoric times the lands of the canton were inhabited by people of the Pfyn culture along Lake Constance. During Roman times the canton was part of the province Raetia until in 450 the lands were settled by the Alamanni.

In the 6th century Thurgovia became a Gau of the Frankish Empire as part of Alemannia, passing to the Duchy of Swabia in the early 10th century. At this time, Thurgovia included not just what is now the canton of Thurgau, but also much of the territory of the modern canton of St. Gallen, the Appenzell and the eastern parts of the canton of Zurich. The most important cities of Thurgovia in the early medieval period were Constance as the seat of the bishop, and St. Gallen for its abbey.
