The new political situation in which they now found themselves required, in many of the colonies, but little departure from these ancient institutions. The chief innovation necessary was, to bring into practical working the authority of the people, in place of that of the crown of England, as the source of all political power. The changes requisite to effect this were of course to be made at once; the materials for these changes existed everywhere, in the representative institutions which had been long a part of the system of every colony since the first settlement of the country. Thus, as we have seen, in all the provincial, the proprietary, and the charter governments, the freemen of the colony had been accustomed to be represented in the government, in some form; and although those governments, with a few exceptions, were under the direct or indirect restraint of the crown, and could all be reached and controlled by the exercise of arbitrary power, the practice of representation, through popular elections, was everywhere known and familiar. The old constitutions of some of the colonies had also been highly democratic, admitting an election of the executive, as well as of the legislature, directly by the people;[135] while, in others, where the executive was appointed by the crown, the second or less numerous branch of the legislature had been elected by the people, either directly, or indirectly through the popular assembly. The foundations, therefore, for popular governments existed in all the colonies, and furnished the means for substituting the new source of political power, the will of the people, in the place of that of an external sovereign.
