followed, and Spitsbergen became a base for hunting the bowhead whale from 1611. Because of the lawless nature of the area, English, Danish, Dutch, and French companies and authorities tried to use force to keep out other countries' fleets. 17th–18th centuries Smeerenburg was one of the first settlements, established by the Dutch in 1619. Smaller bases were also built by the English, Danish, and French. At first the outposts were merely summer camps, but from the early 1630s, a few individuals started to overwinter. Whaling at Spitsbergen lasted until the 1820s, when the Dutch, British, and Danish whalers moved elsewhere in the Arctic. By the late 17th century, Russian hunters arrived; they overwintered to a greater extent and hunted land mammals such as the polar bear and fox. 19th century Norwegian hunting—mostly for walrus—started in the 1790s. The first Norwegian citizens to reach Spitsbergen proper were a number of Coast Sámi people from the Hammerfest region, who were hired as part of a Russian crew for an expedition in 1795. After the Anglo-Russian War in 1809, Russian activity on Svalbard diminished, and ceased by the 1820s. Norwegian whaling was abandoned about the same time as the Russians left, but whaling continued around Spitsbergen until the 1830s, and around Bjørnøya until the 1860s. 20th century Svalbard Treaty and Norwegian sovereignty By the 1890s, Svalbard had become a destination for Arctic tourism, coal deposits had been found, and the islands were being used as a base for Arctic exploration. The first mining was along Isfjorden by Norwegians in 1899; by 1904, British interests had established themselves in Adventfjorden and started the first year-round operations. Production in Longyearbyen, by US interests, started in 1908; and Store Norske established itself in 1916, as did other Norwegian interests during the first world war, in part by buying US interests. Discussions to establish the sovereignty of the archipelago commenced in the 1910s, but were interrupted by World War I. On 9 February 1920, following the Paris Peace Conference, the Svalbard Treaty was signed, granting full sovereignty to Norway. However, all signatory countries were granted non-discriminatory rights to fishing, hunting, and mineral resources. The treaty took effect on 14 August 1925, at the same time as the Svalbard Act regulated the archipelago and the first governor, Johannes Gerckens Bassøe, took office. The archipelago has traditionally been known as Spitsbergen, and the main island as West Spitsbergen. From
