more and more native Swedes started to move to the city, and they soon represented a majority of the population. This demographic shift is reflected by the fact that the city council became homogeneously Swedish after 1652, when the last Dutch councillor died. During these first few decades of its existence, Gothenburg also acquired a fire brigade, which, having been founded in July 1639, is generally reckoned to be the oldest fire brigade in Sweden. Under the Treaty of Roskilde (1658), Denmark–Norway ceded the Danish province of Halland and the Norwegian province of Bohuslän to Sweden, thereby moving the frontiers with both Denmark and Norway away from the Göta Älv and leaving Gothenburg in a much less exposed position. The city was subsequently able to grow into an important port, in part due to the fact that it was one of only two ports on the Swedish west coast (the other being Marstrand), which was granted the right to trade with merchants from other countries. Early modern Gothenburg During the Great Northern War, Gothenburg became the base for privateers attacking Danish-Norwegian shipping, the most famous of these being Lars Gathenhielm, known as Lasse I Gatan. The Danish-Norwegians had their own naval hero in the form of the charismatic Norwegian captain Peder Tordenskjold, who attacked Gothenburg and the network of fortresses surrounding it on several occasions during the years 1717-9, At the beginning of the eighteenth century, fishing was Gothenburg's primary industry, but over the course of the next few decades it came to be eclipsed by trade. In 1731 the Swedish East India Company was founded in Gothenburg, and the city flourished due to its highly profitable commercial expeditions to Asian countries. One of the Company's ships was the Götheborg, which was wrecked in the Gothenburg Archipelago in 1745, on its return from a voyage to China. A replica of the Götheborg was built in 1995-2005 and is now a major tourist attraction. The harbour developed into Sweden's main harbour for trade towards the west, and was the main port of departure for Swedish emigrants to North America. This history is reflected by the foundation of the House of the Emigrants (Emigranternas Hus) museum in the city in 2004. The impact of Gothenburg as a main port of embarkation for Swedish emigrants is reflected by Gothenburg, Nebraska, a small Swedish settlement in the United States. Modern Gothenburg With the 19th
