Turgowe

The Thurgau (Turgowe, Turgovia) was a pagus of the Duchy of Alemannia in the early medieval period. A County of Thurgau (Landgrafschaft Thurgau) existed from the 13th century until 1798. Parts of Thurgau were acquired by the Old Swiss Confederacy during the early 15th century, and the entire county passed to the Confederacy as a condominium in 1460.

The county became the Canton of Thurgau within the Helvetic Republic in 1798, and with the Act of Mediation of 1803 a canton of the restored Confederacy.

The Turgowe pagus within Alemannia was named for the Thur river, and it included the entire Alemannic territory between Rhine and Reuss. With the Alemannic settlement of Central Switzerland in the 8th century, Turgowe included most of what is now Northeastern and Central Switzerland. In the 9th century, Zürichgau was detached from Thurgau, so that Thurgau was now bounded to the west by the Töss basin. (the Allmen range west of the Töss), corresponding in area to what is now Thurgau, Appenzell, parts of St. Gallen (Fürstenland and Toggenburg), and the parts of Zürich east of the Töss.
