I. The parties to this instrument were free, sovereign, and independent political communities,--each possessing within itself all the powers of legislation and government, over its own citizens, which any political society can possess. But, by this instrument, these several States became united together for certain purposes. The instrument was styled, "Articles of Confederation and Perpetual Union between the States," and the political body thus formed was entitled "The United States of America." The Articles declared--as would, indeed, be implied, in such circumstances, without any express declaration--that each State retained its sovereignty, freedom, and independence, and every power, jurisdiction, and right not expressly delegated by the instrument itself to the United States in Congress assembled. The nature and objects of this union were described as a firm league of friendship between the States, for their common defence, the security of their liberties, and their mutual and general welfare; and the parties bound themselves to assist each other against all force offered to or attacks made upon them, or any of them, on account of religion, sovereignty, trade, or under any pretence whatever. It was also provided, that the free inhabitants of each State should be entitled to all the privileges of free citizens in the several States;[152] that there should be an open intercourse and commerce between the different States; that fugitives from justice from one State to another should be delivered up; and that full faith and credit should be given in each State to the records, acts, and judicial proceedings of every other State.[153] II. The government established by the Articles of Confederation consisted of a single representative body, called a General Congress. In this body were vested all the powers, executive, legislative, and judicial, granted to the United States. The members of it were to be chosen by the States, in such manner as the legislature of each State might determine; no State to be represented by more than seven delegates, or by less than two. No delegate was eligible for more than three years in a period of six; and no delegate could hold any office of emolument under the United States. Each State was to maintain its own delegates, and in the determination of questions, the voting was to be by States, each State having one vote. III. It should be remembered, that the objects and purposes of the Confederation related chiefly to the defence of the States against external attacks; and it was, therefore, as it purported to be, a league for mutual defence and protection, through the combined powers of the whole, operating in certain forms and under certain restrictions. For the manner in which this new authority was to be exercised, we are to look at the powers conferred upon "the United States in Congress assembled." These powers related to external and to internal affairs.
