The mayor of the Swiss city of Zürich (Stadtpräsident von Zürich) presides the city council (Stadtrat). The office of mayor (Bürgermeister) was introduced with the guild revolution of 1336, and held by Rudolf Brun until 1360. It was abolished in the Helvetic Republic (1798–1803). In 1803, the title of Bürgermeister was given to the head of the cantonal government, and the office of the city mayor was renamed to Stadtpräsident).
