The city was named after the Geats (Swedish: Götar varied: Geatas, Gautar, Goths, Gotar, Gøtar, Götar), the inhabitants of Gothia, now southern Sweden—i.e. "Geat Castle". The river on which the city sits is the Göta älv or Gothia River. Göta borg "Gothia Fortress" is the fort on the Göta River, built to protect the port.
In the early modern period, the configuration of Sweden's borders made Gothenburg strategically critical as the only Swedish gateway to the North Sea and Atlantic, lying on the west coast in a very narrow strip of Swedish territory between Danish Halland to the south and Norwegian Bohuslen to the north. After several failed attempts, Gothenburg was successfully founded in 1621 by King Gustavus Adolphus (Gustaf II Adolf).
