Christianssand experienced its first fire in 1734, which was devastating to the city. Later in the 18th century, after the American Revolutionary War, the town's shipbuilders experienced a boom that lasted until the Napoleonic Wars, when the continental blockade and naval warfare struck a severe blow to trade. Denmark–Norway supported France in the Wars and was therefore subjected to relentless attack by Britain, as recounted in Ibsen's "Terje Vigen". Only in the 1830s did the economy begin to recover, and the growth in the Norwegian shipping industry was important for Christianssand.
