Gothenburg Municipality (Göteborgs kommun or Göteborgs stad) is a municipality in Västra Götaland County in western Sweden. Its seat is located in the city of Gothenburg. When the first Swedish local government acts were implemented in 1863 the City of Gothenburg, founded and chartered in 1621, became a city municipality with an elected city council (stadsfullmäktige). Its territory has since then been added through amalgamations in 1868, 1906, 1922, 1931, 1945, 1948, 1967 and 1974. The local government reform of 1971 made the city a unitary municipality, like all others in the country. The municipality prefers, however, to style itself Göteborgs stad (City of Göteborg), whenever legally possible.
