The 1700s
In July 1700, Copenhagen underwent a bombardment from a British-Dutch-Swedish navy but did not suffer much damage. From June 1711 to March 1712, it was haunted by the plague which killed about a third of the population.
During the fire of 1728 about a third of the city (the entire northern part), 1,600 houses and five churches burned down in the course of four days. Christian VI tore the old Copenhagen Castle down in 1731–32 to replace it with Christiansborg Palace, and during the reign of Frederick V Frederiksstaden, the most distinguished district of Copenhagen, with Amalienborg Palace at its center, was developed.
Near the end of the 18th century, Copenhagen's trade and the wealth that followed reached its so far highest level. Although the fire of 1795 destroyed about a quarter of the city and rendered 3,500 homeless, the damage was relatively quickly repaired and most of the city was rebuilt by the turn of the 19th century.
