Copenhagen’s History – From the Middle Ages to a Modern Metropolis

1 - The Beginning – A Fishing Village by the Øresund
Copenhagen’s history begins in the 12th century, when the city was a small fishing village called Havn. Its strategic location by the Øresund made it ideal for trade and fishing. Copenhagen’s first major period of growth was driven by Bishop Absalon, who built a castle on Slotsholmen in 1167 to protect the town. This marked the beginning of Copenhagen’s development as an important trading town.
2 - The Middle Ages – A Centre of Trade
During the 13th and 14th centuries, Copenhagen grew in importance as a trading town, particularly because of its location along the Baltic Sea’s trade routes. Walls were built around the town to protect it against attacks, and it began to attract merchants and craftspeople.
In 1443, Copenhagen officially became Denmark’s capital, cementing its importance as a political and economic centre.
3 - The Renaissance – Christian IV’s Golden Era
King Christian IV (1588–1648) left his mark on Copenhagen as a town planner and visionary. Many of the city’s most iconic buildings were constructed during his reign, including the Round Tower, the Stock Exchange and Rosenborg Castle. The city became a cultural and architectural centre in the Nordic region.
4 - Fires, War and Reconstruction
Copenhagen was badly affected by two disasters in the 18th century: the Great Fire of 1728, which destroyed large parts of the city, and the fire of 1795, which devastated further areas. Reconstruction brought wider streets and neoclassical buildings.
During the Napoleonic Wars, Copenhagen was bombarded by the British fleet in 1807, causing extensive destruction. However, the city quickly recovered and once again became an important centre for trade and culture.
5 - Industrialisation and Modernisation
In the 19th century, Copenhagen experienced rapid population growth and industrialisation. The ramparts that had previously surrounded the city were demolished, making room for what are now the districts of Vesterbro, Nørrebro and Østerbro.
6 - Copenhagen in the 20th Century
During the Second World War, Copenhagen was occupied by Germany, but the city played a central role in the resistance movement. After the war, Copenhagen enjoyed a period of economic and cultural flourishing.
Today, Copenhagen is known as one of the world’s most sustainable and cycle-friendly cities. With its green initiatives, modern architecture and rich history, it serves as a model for many cities around the world.
