The story
Kongsberg was founded by Danish-Norwegian King Christian IV as a mining community in 1624 after the discovery of silver. In its second year, the town of Kongsberg and the Kongsberg Silver Mines began. According to official records, silver was first discovered by the shepherds children Helga Verp and Jacob Grosvold in the summer of 1623. However, the existence of deposits of precious metals was known previously, as evidenced by indications of earlier silver mining. With the rise of silver mining, Kongsberg became the largest industrial center in Norway before the industrial revolution. At the peak of silver mining in the early eighteenth century, Kongsberg's silver mines and related industries contributed 10% of the Denmark–Norway gross national product.
To develop the Kongsberg Silver Mines, Christian IV hired Germans from the silver mines of Saxony and Harz and brought in Germans from other mines in Norway. The Germans brought their knowledge of mining technology, especially important during the start-up phase. Before 1623, the city was located in the royal territory of Sandsvær.
Four years after the establishment of the Kongsberg Silver Mines, most of the 1,500 workers and officials were still German. Gradually, Norwegians entered the workforce and were hired as supervisors. In 1636, 1,370 Germans and 1,600 Norwegians were employed there. In 1648, there were 1,500 Germans and 2,400 Norwegians working in Kongsberg.
Gunpowder was officially introduced in mining in 1681. Mining in the particularly hard rock of Kongsberg Mountain was energy intensive, so the silver mine continued to develop new technology to reduce production costs. A large artificial dam powered the mine's hoists before electricity was introduced. In 1624, a road from Hokksund to Kongsberg was built to serve the Kongsberg Silver Mines, the most important road built in Norway in the 17th century. In 1665, the road was extended to Kristiansand and Larvik.
By 1683, the mining industry was an important industry of the state. The rapid development of Kongsberg meant that the number of workers in the city had increased significantly by the end of the 17th century. The proportion of Norwegians in the workforce increased, but for a long time, the main staff was dominated by Germans. Kongsberg was almost an outpost of Germany in Norway: the mine had a German name, and the official language was German, only later becoming bilingual (German and Danish). In Kongsberg, the German mountain justice system was also used. Legally, this means that the city was bound by independent regulations, partially separating the mining community from the country's legal system. The Germans brought with them the Knappschaft, a guild-like association of miners that provided including free medical assistance, a pension plan, worker sick leave and a Saturday break. The ring agriculture characteristic of Kongsberg may also have been inspired by the German pattern.
The proceeds from silver mining provided a valuable assistance to the tight finances of Denmark. Denmark–Norway relied heavily on the silver of Kongsberg to support an ongoing war against Sweden. Precious metals also became more and more important in the currency, and to get closer to its source of raw materials, the Royal Mint moved in 1686 from Akershus to Kongsberg. During the Great Northern War in 1716, the city became the main target of Karl XII's foray into Norderhof.
Kongsberg was particularly known for its Kongsberg Silver Mines and their high purity. Kongsberg's ore also contained a certain amount of gold and large amounts of copper, cobalt, lead-zinc and fluorite. Roughly 15,750 tonnes (34,720,000 lb) of silver was extracted between the discovery of the silver ore seams in 1623 and the last year of mining in 1957. The workforce at the Kongsberg silver mine began to increase substantially at the end of the 17th century. In the 1769 census, the mines employed about 4,000 workers. With 8,000 inhabitants in all, the town was the second largest in Norway, after Bergen (and thus larger than today's capital, Oslo).
In Norway's 1749 census, Kongsberg was the most populous town in Eastern Norway. It was granted its royal charter of trade—amounting to official township—in 1802. Following several hard years with reduced silver output from the mines, the war of 1807–1814, and a severe town fire in 1810 where 56 houses on the west side were destroyed, mining was complemented by the government establishing a defense industry in 1814. By 1835, the population had declined to 3,540.

Kongsberg is home to the Royal Norwegian Mint (Norwegian: Det Norske Myntverket), which mints Norwegian coins and also produces circulating and collectors' coins for other countries such as Israel. It was established in 1686, and was renamed from the Royal Norwegian Mint (Norwegian: Den Kongelige Mynt) in 2004 after having been sold to private investors (the Mint of Finland and Norwegian company Samlerhuset) in 2003. Kongsberg is also the site of the Kongsberg School of Mines (Kongsberg Bergseminar), an academic institution for mining technology which operated from 1757 to 1814.
During peaceful times, the defence industry gradually evolved into many other kinds of high tech activities as well, now dominating the town's employment. In 1987, however, the state-owned Kongsberg Weapons Factory (Kongsberg Vaapenfabrikk) suffered a major financial crisis as well as accusations of breaching the CoCom rules by selling sensitive technology to the Soviet bloc. As a result, the company was split into several smaller units and partly sold to private investors. Today, the separate firms thrive as one of Norway's main high-tech industrial clusters, centering on the defence and maritime company Kongsberg Gruppen which is listed on the Oslo Stock Exchange.
