Kragerø received a town charter in 1666, making it a markettown and giving its merchant citizens monopoly rights on trade, while Brevik gained a lesser town’s trading rights in 1680. Its merchants were required tobe legal citizens of Skien, a larger nearby market town. It did not become a full market town until 1845. The combination of export and import were of vital importance to the development of shipping. Denmark, France, Holland, Great Britain and Germany were important trading partner nations.
