Thurgau (German:  Thurgau (help·info), anglicized as Thurgovia) is a northeast canton of Switzerland. The population, as of December 2011^[update], is 250,640. In 2007, there were a total of 47,390 (or 19.9% of the population) who were resident foreigners. The capital is Frauenfeld.

In prehistoric times the lands of the canton were inhabited by people of the Pfyn culture along the lake. 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.

The dukes of Zähringen and the counts of Kyburg took over much of the land in the High Middle Ages. When the Kyburg dynasty became extinct in 1264 the Habsburgs took over that land. The town of Zürich was part of the Thurgau until it became reichsunmittelbar in 1218.^{[dubious – discuss]}

Nancy Sandra Sinatra (born June 8, 1940) is an American singer and actress. She is the daughter of singer/actor Frank Sinatra, and remains best known for her 1966 signature hit "These Boots Are Made for Walkin'".

Other defining recordings include "Sugar Town", the 1967 number one "Somethin' Stupid" (a duet with her father), the title song from the James Bond film You Only Live Twice, several collaborations with Lee Hazlewood such as "Jackson", and her cover of Cher's "Bang Bang (My Baby Shot Me Down)", which features during the opening sequence of Quentin Tarantino's Kill Bill.

Sinatra began her career as a singer and actress in the early 1960s, but initially achieved success only in Europe and Japan. In early 1966 she had a transatlantic number-one hit with "These Boots Are Made for Walkin'", which showed her provocative but good-natured style, and which popularized and made her synonymous with go-go boots. The promo clip featured a big-haired Sinatra and six young women in tight tops, go-go boots and mini-skirts. The song was written by Lee Hazlewood, who wrote and produced most of her hits and sang with her on several duets, including the critical and cult favorite "Some Velvet Morning". In 1966 and 1967, Sinatra charted with 13 titles, all of which featured Billy Strange as arranger and conductor.
