Before the thirteen colonies became a confederation of independent States they were associated only by community of transatlantic origin, by geographical position, and by the mutual tie of common dependence on Great Britain. When that tie was sundered they severally assumed the powers and rights of absolute self-government. The municipal and social institutions of each, its laws of property and of personal relation, even its political organization, were such only as each one chose to establish, wholly without interference from any other. In the language of the Declaration of Independence, each State had "full power to levy war, conclude peace, contract alliances, establish commerce, and to do all other acts and things which independent states may of right do." The several colonies differed in climate, in soil, in natural productions, in religion, in systems of education, in legislation, and in the forms of political administration, and they continued to differ in these respects when they voluntarily allied themselves as States to carry on the War of the Revolution. The object of that war was to disenthrall the united colonies from foreign rule, which had proved to be oppressive, and to separate them permanently from the mother country. The political result was the foundation of a Federal Republic of the free white men of the colonies, constituted, as they were, in distinct and reciprocally independent State governments. As for the subject races, whether Indian or African, the wise and brave statesmen of that day, being engaged in no extravagant scheme of social change, left them as they were, and thus preserved themselves and their posterity from the anarchy and the ever-recurring civil wars which have prevailed in other revolutionized European colonies of America. When the confederated States found it convenient to modify the conditions of their association by giving to the General Government direct access in some respects to the people of the States, instead of confining it to action on the States as such, they proceeded to frame the existing Constitution, adhering steadily to one guiding thought, which was to delegate only such power as was necessary and proper to the execution of specific purposes, or, in other words, to retain as much as possible consistently with those purposes of the independent powers of the individual States. For objects of common defense and security, they intrusted to the General Government certain carefully defined functions, leaving all others as the undelegated rights of the separate independent sovereignties.
