But whatever may be the importance of such changes, they neither affect a State as an International Person, nor affect the personal identity of the States concerned. France, for instance, has retained her personal identity from the time the Law of Nations came into existence until the present day, although she acquired and lost parts of her territory, changed her dynasty, was a kingdom, a republic, an empire, again a kingdom, again a republic, again an empire, and is now, finally as it seems, a republic. All her international rights and duties as an International Person remained the very same throughout the centuries in spite of these important changes in her condition and appearance. Even such loss of territory as occasions the reduction of a Great Power to a small Power, or such increase of territory and strength as turns a small State into a Great Power, does not affect a State as an International Person. Thus, although through the events of the years 1859-1861 Sardinia acquired the whole territory of the Italian Peninsula and turned into the Great Power of Italy, she remained one and the same International Person.
[Sidenote: Changes affecting States as International Persons.]
§ 78. Changes which affect States as International Persons are of different character.
(1) As in a Real Union the member-States of the union, although fully independent, make one International Person,[108] two States which hitherto were separate International Persons are affected in that character by entering into a Real Union. For through that change they appear henceforth together as one and the same International Person. And should this union be dissolved, the member-States are again affected, for they now become again separate International Persons.
[Footnote 108: See below, § 87, where the character of the Real Union is fully discussed.]
(2) Other changes affecting States as International Persons are such changes as involve a partial loss of independence on the part of the States concerned. Many restrictions may be imposed upon States without interfering with their independence proper,[109] but certain restrictions involve inevitably a partial loss of independence. Thus if a hitherto independent State comes under the suzerainty of another State and becomes thereby a half-Sovereign State, its character as an International Person is affected. The same is valid with regard to a hitherto independent State which comes under the protectorate of another State. Again, if several hitherto independent States enter into a Federal State, they transfer a part of their sovereignty to the Federal State and become thereby part-Sovereign States. On the other hand, if a vassal State or a State under protectorate is freed from the suzerainty or protectorate, it is thereby affected as an International Person, because it turns now into a full Sovereign State. And the same is valid with regard to a member-State of a Federal State which leaves the union and gains the condition of a full Sovereign State.
