1. I need not dwell on what has been so often discussed and so much misunderstood; and yet I must remind you of the power of Congress over the Rebel States from _the necessity of the case_; because, after the overthrow of legitimate governments, whose members were sworn to support the Constitution of the United States, there was no other rule possible for these States than that of Congress,--precisely as the Territories, according to Chief Justice Marshall, in a famous judgment, fell under “the power and jurisdiction of the United States” from the necessity of the case.[257] I do not say that a State becomes a technical Territory, as that term is understood among us; but I do say, that, in the lapse of the Rebel States, and in the absence of legitimate governments with members sworn to support the Constitution, these States fell under “the power and jurisdiction of the United States,”--meaning, practically, Congress,--until such time as they are reorganized according to the requirement of the Constitution. In the exercise of such a power and jurisdiction thus cast upon it, Congress must see that all loyal citizens, without distinction of color, take part in the formation of the new governments.[258] * * * * * 2. Nor need I dwell on another source of power, found in _the rights of war_; but this, too, must be made plain. Nobody doubts that the United States were justified in asserting supremacy in the Rebel States by force of arms. But the war, when once begun, was subject to all the conditions of war, according to the rights of war found in the Law of Nations,--doubly obligatory on us, first, because we belong to the family of nations, and, secondly, because the Law of Nations is expressly recognized by the Constitution itself. Now, according to the rights of war found in the Law of Nations, a conquering power is justified in requiring not only indemnity for the past, but security for the future. It depends upon the people of the United States, represented in Congress, to determine the guaranties of this security. In support of this conclusion, I ask attention to a familiar authority, whose statement seems to cover the case. I read from Vattel:-- “The whole right of the conqueror comes from that just self-defence which comprehends the maintenance and prosecution of his rights. When, therefore, he has entirely subdued a hostile nation, he may undoubtedly, in the first place, do himself justice with regard to that which gave rise to the war, and indemnify himself for the expenses and damages it has caused him; he may, according to the exigency of the case, impose penalties upon the conquered nation by way of example; he may even, if prudence require, _render it incapable of doing harm so easily in future_.”[259]
