Göteborg, Sweden, was founded in 1621 by King Gustavus Adolphus. It lies by the sea at the mouth of Göta Älv—the river running through the city—and became the largest seaport in the Nordic countries. The city was heavily influenced by the Dutch. Dutch city planners were contracted to build the city as they had the skills needed to build in the marshy areas around the city. The town was designed like Dutch cities such as Amsterdam. The plan of the streets and canals of Gothenburg closely resembles that of Jakarta, which was built by the Dutch around the same time. The Dutchmen initially won political power and it was not until 1652, when the last Dutch politician in the city's council died, that the Swedes acquired political power over Gothenburg. In the Treaty of Roskilde (1658) Denmark-Norway ceded the then Danish province Halland, to the south, and the Norwegian province of Bohus County or Bohuslän to the north, leaving Gothenburg in a less exposed position. Gothenburg was able to grow into an important port and trade centre on the west coast thanks to the fact that it was the only city on the west coast that was granted, together with Marstrand, the rights to trade with merchants from other countries. http://en.wikipedia.org/wiki/Gothenburg
