The polar archipelago of Svalbard was first discovered by Willem Barentsz in 1596, although there is disputed evidence of use by Pomors or Norsemen. Whaling for bowhead whales started in 1611, dominated by English and Dutch companies, though other countries participated. At that time there was no agreement about sovereignty. Whaling stations, the largest being Smeerenburg, were built during the 17th century, but gradually whaling decreased. Hunting was carried out from the 17th century by Pomors, but from the 19th century it became more dominated by Norwegians.
Exploration was initially conducted to find new whaling grounds, but from the 18th century some scientific expeditions took place. These were initially large scale, but from the late 19th century they became smaller and increasingly focused on the interior. The most important scientific explorers were Baltazar Mathias Keilhau, Adolf Erik Nordenskiöld and Martin Conway. Sustainable mining started in 1906 with the establishment of Longyearbyen and by the 1920s, permanent coal mining settlements had been established at Barentsburg, Grumant, Pyramiden, Svea and Ny-Ålesund. The Svalbard Treaty came into effect in 1925, granting Norway sovereignty of the archipelago, but prohibiting "warlike activities" and establishing all signatories the right to mine. This both eliminated the mare liberum status of the islands, and also saw a name change from the Spitsbergen Archipelago to Svalbard. By the 1930s, all settlements were either Norwegian or Soviet.
During the Second World War, the settlements were first evacuated and then bombed by the Kriegsmarine, but rebuilt after the war. During the Cold War there were increased tensions between Norway and the Soviet Union, particularly regarding the building of an airport. There was limited oil drilling, and by 1973 more than half the archipelago was protected. Starting in the 1970s, Longyearbyen underwent a process of "normalization" to become a regular community. Arktikugol closed Grumant in 1962 and Pyramiden in 1998, while King Bay had to close mining at Ny-Ålesund after the Kings Bay Affair. The 1990s and 2000s have seen major reductions of the Russian population and the creation of scientific establishments in Ny-Ålesund and Longyearbyen. Tourism has also increased and become a major component of the economy of Longyearbyen.
