To France it became a haven for privateers, the bane of England's commerce in the Channel and the North Sea.

As the French sea power waned, England in treaty after treaty exacted the dismantling of the works of Dunkirk, which it may be said in passing was the home port of the celebrated Jean Bart and other great French privateersmen.
Meanwhile the greatest and wisest of Louis' ministers, Colbert, was diligently building up that system of administration, which, by increasing and solidly basing the wealth of the State, should bring a surer greatness and prosperity than the king's more showy enterprises.
With those details that concern the internal development of the kingdom this history has no concern, beyond the incidental mention that production, both agricultural and manufacturing, received his careful attention; but upon the sea a policy of skilful aggression upon the shipping and commerce of the Dutch and English quickly began, and was instantly resented.

Great trading companies were formed, directing French enterprise to the Baltic, to the Levant, to the East and West Indies; customs regulations were amended to encourage French manufactures, and to allow goods to be stored in bond in the great ports, by which means it was hoped to make France take Holland's place as the great warehouse for Europe, a function for which her geographical position eminently fitted her; while tonnage duties on foreign shipping, direct premiums on home-built ships, and careful, rigorous colonial decrees giving French vessels the monopoly of trade to and from the colonies, combined to encourage the growth of her mercantile marine.

England retaliated at once; the Dutch, more seriously threatened because their carrying-trade was greater and their home resources smaller, only remonstrated for a time; but after three years they also made reprisals.

Colbert, relying on the great superiority of France as an actual, and still more as a possible producer, feared not to move steadily on the grasping path marked out; which, in building up a great merchant shipping, would lay the broad base for the military shipping, which was being yet more rapidly forced on by the measures of the State.
