consequences;--first, that, as they were distinct nations, they could not be treated as part of the subjects of any one of the States, or of the United States; and secondly, that, as their intercourse and trade were subjected to restraint, that restraint would be most appropriately exercised by the federal power. So general was the acquiescence in these necessities imposed by the principle of public law which defined the condition of the Indian tribes, that during the whole of the thirteen years which elapsed from the commencement of the Revolution to the adoption of the Constitution, the regulation of intercourse with those tribes was left to the federal authority. It was tacitly assumed by the Revolutionary Congress, and it was expressly conferred by the Articles of Confederation. The provision of the Confederation on this subject gave to the United States the exclusive right and power "of regulating the trade and managing all affairs with the Indians not members of any of the States, provided that the legislative right of any State within its own limits be not infringed or violated." The exception of such Indians as were members of any State, referred to those broken members of tribes who had lost their nationality, and had become absorbed as individuals into the political community of the whites. With all other Indians, remaining as distinct and self-governing communities, trade and intercourse were subject to the regulation of Congress; while at the same time each State retained to itself the regulation of its commerce with all other nations. The broad distinction thus early established, and thus perpetuated in the Confederation, between commerce with the Indian tribes, and commerce with "foreign nations," explains the origin and introduction of a special provision for the former, as distinguished from the latter, in the Constitution of the United States. For although there might have been some reason to contend that commerce with "foreign nations"--if the grant of the commercial power had not expressly embraced the Indian tribes--would have extended to those tribes, as nations foreign to the United States, yet the entire history of the country, and the peculiarity of the intercourse needful for their security, made it eminently expedient that there should be a distinct recognition of the Indian communities, in order that the power of Congress to regulate all commerce with them might not only be as ample as that relating to foreign nations, but might stand upon a distinct assertion of their condition as _tribes_. Accordingly, Mr. Madison introduced the separate proposition "to regulate affairs with the Indians, as well within as without the limits of the United States";[244] and the committee to whom it was referred gave effect to it, by adding the words, "and with the Indian tribes," to the end of the clause containing the grant of the commercial power.[245]
