It was not for the sake of the colonists that England had assisted them in driving the French from America, but with the wholly selfish aim of building up the trade and commerce of Great Britain. European nations looked upon their American colonies simply as resources from which the mother country might become enriched, and in this respect the policy of England was not different from that of Spain, described in the beginning of this volume. As early as 1625 an English author (Hagthorne) wrote that even in time of peace it was the purpose and aim of England to undermine and beat the Dutch and Spaniards out of their trades, "which may not improperly be called a war, for the deprivation and cutting off the trades of a kingdom may be to some prince more loss if his revenues depend thereon than the killing of his armies." The wars against Holland, which resulted in the subjection to the British crown of the colonial possessions of that industrious people, and which compelled the fleets of the United Provinces to acknowledge British supremacy on the high seas, were in the line of commercial aggrandizement, and the Navigation Act transferred to England a large share of the Dutch carrying trade, and enriched English shipowners with an utterly selfish indifference to the welfare of English colonies. When the colonists, their western bounds no longer threatened by civilized foes, their plantations flourishing and their seaport towns wealthy with the profits of a commerce carried on in contempt of imperial restrictions, began to feel and to assert that they were entitled to all the rights of freeborn Englishmen, and to the same commercial and industrial independence enjoyed by loyal subjects in England, they were surprised to learn that Parliament and the English people regarded them not as freemen, but as tributaries. The colonists were themselves loyal, even up to the hour when they were compelled by stubborn tyranny to assert the right of revolution, for, to quote the language of John Adams, "it is true there always existed in the colonies a desire of independence of Parliament in the articles of internal taxation and internal policy, and a very general, if not universal opinion, that they were constitutionally entitled to it, and as general a determination to maintain and defend it. But there never existed a desire of independence of the Crown, or of general regulations of commerce for the equal and impartial benefit of all parts of the empire." "If any man," said the same great statesman, "wishes to investigate thoroughly the causes, feelings and principles of the Revolution, he must study this Act of Navigation, and the Acts of Trade, as a philosopher, a politician and a philanthropist."
