Thus, in these first English settlements, the deliberate encouragement of varieties of type was from the outset a distinguishing note, and the home authorities neither desired nor attempted to impose a strict uniformity with the rules and methods existing in England. There was as great a variety in social and economic organisation as in religious beliefs between the aristocratic planter colonies of the south and the democratic agricultural settlements of New England. In one thing only was there uniformity: every settlement possessed self-governing institutions, and prized them beyond all other privileges. None, indeed, carried self-government to so great an extent as the New Englanders. They came out organised as religious congregations, in which every member possessed equal rights, and they took the congregational system as the basis of their local government, and church membership as the test of citizenship; nor did any other colonies attain the right, long exercised by the New Englanders, of electing their own governors. But there was no English settlement, not even the little slave-worked plantations in the West Indian islands, like Barbados, which did not set up, as a matter of course, a representative body to deal with problems of legislation and taxation, and the home government never dreamt of interfering with this practice. Already in 1650, the English empire was sharply differentiated from the Spanish, the Dutch, and the French empires by the fact that it consisted of a scattered group of self-governing communities, varying widely in type, but united especially by the common possession of free institutions, and thriving very largely because these institutions enabled local needs to be duly considered and attracted settlers of many types. (b) The Period of Systematic Colonial Policy, 1660-1713 The second half of the seventeenth century was a period of systematic imperial policy on the part of both England and France; for both countries now realised that in the profitable field of commerce, at any rate, the Dutch had won a great advantage over them.
