In teaching the history of Europe from the Treaty of Westphalia to the beginning of the French Revolution, no mistake is commoner than the one of regarding the almost continuous series of wars between the European States as a purposeless struggle for territorial aggrandizement. Equally in American history, the teacher is prone to allow his interest in the growth of social and political institutions to obscure the fact that the North American continent was, for nearly a century, merely a distant battleground on which Holland, England and France were struggling for commercial supremacy. “Unity is given to the history of England in the eighteenth century,” says Seeley (“Expansion of England,” p. 77), “if you remark the single fact that Greater Britain during that period was establishing itself in opposition to Greater France.... You will, I think, find it very helpful in studying the history of those two countries always to bear in mind that throughout most of that period the five States of Western Europe all alike are not properly European States but world States, and that they debate continually among themselves a mighty question, which is not European at all and which the student with his eye fixed on Europe is too apt to disregard, namely, the question of the possession of the New World.” In the same way, the student of American history must be continually reminded that he is studying not the history of half a dozen or more isolated communities, but a phase of a great European struggle for world power. Struggle with the Dutch. From 1689 to 1763, this struggle is marked by an almost continuous war between France and England. An earlier generation, however, witnessed a similar struggle between Holland and England. This earlier struggle is also vitally important in the history of North America. Few students of American history are aware of the unprecedented growth of the Dutch maritime power during the first half of the seventeenth century. To most of them the founding of New Netherlands is an isolated fact, comparatively unimportant because the Dutch colony ultimately fell into the hands of the English. The fact nevertheless remains that throughout the greater part of the seventeenth century the carrying trade of the world was in the hands of the Dutch and Amsterdam was the exchange of the world. What Venice had been in the fifteenth century, Amsterdam became in the seventeenth.
