Sweden grow into a major European power, reflected in the development of the city of Stockholm. From 1610 to 1680 the population multiplied sixfold. In 1634 Stockholm became the official capital of the Swedish empire. Trading rules were also created that gave Stockholm an essential monopoly over trade between foreign merchants and other Swedish and Scandinavian territories.
In 1710 a plague killed about 20,000 (36 percent) of the population. After the end of the Great Northern War the city stagnated. Population growth halted and economic growth slowed. The city was in shock after having lost its place as the capital of aGreat Power. However Stockholm maintained its role as the political centre of Sweden and continued to develop culturally under Gustav III.
By the second half of the 19th century, Stockholm had regained its leading economic role. New industries emerged and Stockholm was transformed into an important trade and service centre as well as a key gateway point within Sweden. The population also grew dramatically during this time, mainly through immigration. At the end of the 19th century, less than 40% of the residents were Stockholm-born. Settlement began to expand outside the city limits. The 19th century saw the establishment of a number of scientific institutes, including the Karolinska Institute. The General Art and Industrial Exposition was held in 1897.
Stockholm became a modern, technologically advanced, and ethnically diverse city in the latter half of the 20th century. Many historical buildings were torn down during the modernist era, including substantial parts of the historical district of Klara, and replaced with modern architecture. However, in many other parts of Stockholm (such as in Gamla Stan, S�dermalm, �stermalm, Kungsholmen and Vasastan), many "old" buildings, blocks and streets built before the modernism and functionalism movements took off in Sweden (around 1930-1935) survived this era of demolition.
