History
The western coast was a frontier for most of its history. Bohuslän belonged to Norway and Halland to Denmark, leaving Sweden only a narrow outlet to the sea at the mouth of the Göta river, guarded by Älvsborg fortress. Long before, Bronze Age farmers carved ships, weapons and figures into the granite around Tanum, and Iron Age and Viking chieftains held the fertile plains of Västergötland, which has a strong claim as one of the cradles of the Swedish kingdom, with the early bishopric at Skara.
Gothenburg was founded in 1621 by Gustavus Adolphus to give Sweden a North Sea port free of Danish tolls. Dutch engineers laid out its canals and grid, and Dutch, German and Scottish merchants settled there. In 1658 the Treaty of Roskilde brought Bohuslän and Halland permanently under Swedish rule, and the fortress of Carlsten was built at Marstrand to hold Bohuslän. Magnus Gabriel De la Gardie rebuilt Läckö Castle on Lake Vänern in the same era.
The Swedish East India Company, founded in 1731, made Gothenburg rich on tea and porcelain from China. The 19th century brought textile mills around Borås, the Trollhätte canal linking Vänern to the sea, and herring booms on the Bohuslän coast. In the 20th century Gothenburg became Sweden's industrial capital, with the SKF ball-bearing works and Volvo, which built its first car there in 1927, and huge shipyards that closed in the crises of the 1970s and 1980s.
