There is no lack of detailed narratives, both of the entire period covered by the present volume and, on an even larger scale, of certain of its more important or dramatic episodes. New material brought to light within the past decade or two, however, has necessitated a revaluation of many former judgments, as well as changes in selection and emphasis. Moreover, our general accounts do not, for the most part, adequately treat of those economic and imperial relations which are of fundamental importance; for the one outstanding fact concerning any American colony in the colonial period is that it was a dependency, and formed merely a part of a larger and more comprehensive imperial and economic organization. Consequently, the evolution of such a colony can be viewed correctly only when it is seen against the background of the economic and imperial conditions and theories of the time. While the author, accordingly, has endeavored to place the local story in its proper imperial setting, he has endeavored also to distinguish between its various elements, and to display the conflicting forces at work in the colonies themselves. The old conception of New England history, according to which that section was considered to have been settled by persecuted religious refugees, devoted to liberty of conscience, who, in the disputes with the mother-country, formed a united mass of liberty-loving patriots unanimously opposed to an unmitigated tyranny, has, happily, for many years, been passing. In his own narrative of the facts, based upon a fresh study of the sources, the author has tried to indicate that economic as well as religious factors played a very considerable part in the great migration during the early settlement period, in the course of which over sixty-five thousand Englishmen left their homes for various parts of the New World, of which number approximately only four thousand were to join the New England churches. He has also endeavored to exhibit the workings of the theocracy, and to show how, in the period treated, the domestic struggle against the tyranny exercised by the more bigoted members of the theocratic party was of greater importance in the history of liberty than the more dramatic contest with the mother-country.
