§ 88. Confederated States (Staatenbund) are a number of full Sovereign States linked together for the maintenance of their external and internal independence by a recognised international treaty into a union with organs of its own, which are vested with a certain power over the member-States, but not over the citizens of these States. Such a union of Confederated States is not any more itself a State than a Real Union is; it is merely an International Confederation of States, a society of international character, since the member-States remain full Sovereign States and separate International Persons. Consequently, the union of Confederated States is not an International Person, although it is for some parts so treated on account of its representing the compound power of the full Sovereign member-States. The chief and sometimes the only organ of the union is a Diet, where the member-States are represented by diplomatic envoys. The power vested in the Diet is an International Power which does not in the least affect the full sovereignty of the member-States. That power is essentially nothing else than the right of the body of the members to make war against such a member as will not submit to those commandments of the Diet which are in accordance with the Treaty of Confederation, war between the member-States being prohibited in all other cases.
History has shown that Confederated States represent an organisation which in the long run gives very little satisfaction. It is for that reason that the three important unions of Confederated States of modern times—namely, the United States of America, the German, and the Swiss Confederation—have turned into unions of Federal States. Notable historic Confederations are those of the Netherlands from 1580 to 1795, the United States of America from 1778 to 1787, Germany from 1815 to 1866, Switzerland from 1291 to 1798 and from 1815 to 1848, and the Confederation of the Rhine (Rheinbund) from 1806 to 1813. At present there is no union of Confederated States. The last in existence, the major Republic of Central America,[131] which comprised the three full Sovereign States of Honduras, Nicaragua, and San Salvador, and was established in 1895, came to an end in 1898.

Federal States (Bundesstaaten).
§ 89. A Federal State[132] is a perpetual union of several Sovereign States which has organs of its own and is invested with power, not only over the member-States, but also over their citizens. The union is based, first, on an international treaty of the member-States, and, secondly, on a subsequently accepted constitution of the Federal State. A Federal State is said to be a real State side by side with its member-States because its organs have a direct power over the citizens of those member-States. This power was established by American[133] jurists of the eighteenth century as a characteristic distinction of a Federal State from Confederated States, and Kent as well as Story, the two later authorities on the Constitutional Law of the United States, adopted this distinction, which is indeed kept up until to-day by the majority of writers on politics. Now if a Federal State is recognised as a State of its own, side by side with its member-States, it is evident that sovereignty must be divided between the Federal State on the one hand, and, on the other, the member-States. This division is made in this way, that the competence over one part of the objects for which a State is in existence is handed over to the Federal State, whereas the competence over the other part remains with the member-States. Within its competence the Federal State can make laws which bind the citizens of the member-States directly without any interference of these member-States. On the other hand, the member-States are totally independent as far as their competence reaches.
[132] The distinction between Confederated States and a Federal State is not at all universally recognised, and the terminology is consequently not at all the same with all writers on International Law.
[133] When in 1787 the draft of the new Constitution of the United States, which had hitherto been Confederated States only, was under consideration by the Congress at Philadelphia, three members of the Congress—namely, Alexander Hamilton, James Madison, and John Jay—made up their minds to write newspaper articles on the draft Constitution with the intention of enlightening the nation which had to vote for the draft. For this purpose they divided the different points among themselves and treated them separately. All these articles, which were not signed with the names of their authors, appeared under the common title "The Federalist." They were later on collected into book-form and have been edited several times. It is especially Nos. 15 and 16 of "The Federalist" which establish the difference between Confederated States and a Federal State in the way mentioned in the text above.
For International Law this division of competence is only of interest in so far as it concerns competence in international matters. Since it is always the Federal State which is competent to declare war, make peace, conclude treaties of alliance and other political treaties, and send and receive diplomatic envoys, whereas no member-State can of itself declare war against a foreign State, make peace, conclude alliances and other political treaties, the Federal State, if recognised, is certainly an International Person of its own, with all the rights and duties of a sovereign member of the Family of Nations. On the other hand, the international position of the member-States is not so clear. It is frequently maintained that they have totally lost their position within the Family of Nations. But this opinion cannot stand if compared with the actual facts. Thus, the member-States of the Federal State of Germany have retained their competence to send and receive diplomatic envoys, not only in intercourse with one another, but also with foreign States. Further, the reigning monarchs of these member-States are still treated by the practice of the States as heads of Sovereign States, a fact without legal basis if these States were no longer International Persons. Thirdly, the member-States of Germany as well as of Switzerland have retained their competence to conclude international treaties between themselves without the consent of the Federal State, and they have also retained the competence to conclude international treaties with foreign States as regards matters of minor interest. If these facts[134] are taken into consideration, one is obliged to acknowledge that the member-States of a Federal State can be International Persons in a degree. Full subjects of International Law, International Persons with all the rights and duties regularly connected with the membership of the Family of Nations, they certainly cannot be. Their position, if any, within this circle is overshadowed by their Federal State, they are part-Sovereign States, and they are, consequently, International Persons for some parts only.
[134] See Riess, "Auswärtige Hoheitsrechte der deutschen Einzelstaaten"(1905).
But it happens frequently that a Federal State assumes in every way the external representation of its member-States, so that, so far as international relations are concerned, the member-States do not make an appearance at all. This is the case with the United States of America and all those other American Federal States whose Constitution is formed according to the model of that of the United States. Here the member-States are sovereign too, but only with regard to internal[135] affairs. All their external sovereignty being absorbed by the Federal State, it is certainly a fact that they are not International Persons at all so long as this condition of things lasts.
