Copenhagen is rich in history. The Danish capital was officially founded in 1167 by Bishop Absalon, but research suggest that the location was inhabited already in the late Viking age. Copenhagen was a busy and strategically important merchant city throughout the medieval period where it controlled much of the lucrative trade and traffic to and from the Baltic Sea.
