Zurich is the largest city in Switzerland and the capital of the canton of Zürich. The city is Switzerland's main commercial and cultural centre and sometimes called the Cultural Capital of Switzerland, the political capital of Switzerland being Berne. Zürich can be counted as one of the world's preeminent global cities. According to several surveys from 2006 to 2008, Zürich was named the city with the best quality of life in the world as well as the wealthiest city in Europe.

The blue and white coat of arms of Zürich is attested from 1389, and was derived from banners with blue and white stripes in use since 1315 . The first certain testimony of banners with the same design is from 1434. The coat of arms is flanked by two lions. The red Schwenkel on top of the banner had varying interpretations: For the people of Zürich, it was a mark of honour, granted by Rudolph I. Zürich's neighbors mocked it as a sign of shame, commemorating the loss of the banner at Winterthur in 1292.
