International Position of Vassal States.
§ 91. The fact that the relation between the suzerain and the vassal always depends upon the special case, excludes the possibility of laying down a general rule as regards the position of Vassal States within the Family of Nations. It is certain that a Vassal State as such need not have any position whatever within the Family of Nations. In every case in which a Vassal State has absolutely no relations whatever with other States, since the suzerain absorbs these relations entirely, such vassal remains nevertheless a half-Sovereign State on account of its internal independence, but it has no position whatever within the Family of Nations, and consequently is for no part whatever an International Person and a subject of International Law. This is the position of the Indian Vassal States of Great Britain, which have no international relations whatever either between themselves or with foreign States.[138] Yet instances can be given which demonstrate that Vassal States can have some small and subordinate position within that family, and that they must in consequence thereof in some few points be considered as International Persons. Thus Egypt can conclude commercial and postal treaties with foreign States without the consent of suzerain Turkey, and Bulgaria could, while she was under Turkish Suzerainty, conclude treaties regarding railways, post, and the like. Thus, further, Egypt can send and receive consuls as diplomatic agents, and so could Bulgaria while she was a Turkish Vassal State. Thus, thirdly, the former South African Republic, although in the opinion of Great Britain under her suzerainty, could conclude all kinds of treaties with other States, provided Great Britain did not interpose a veto within six months after receiving a copy of the draft treaty, and was absolutely independent in concluding treaties with the neighbouring Orange Free State. Again, Egypt possesses, since 1898, together with Great Britain condominium[139] over the Soudan, which means that they exercise conjointly sovereignty over this territory. Although Vassal States have not the right to make war independently of their suzerain, Bulgaria, at the time a Vassal State, nevertheless fought a war against the full-Sovereign Servia in 1885, and Egypt conquered the Soudan conjointly with Great Britain in 1898.

How could all these and other facts be explained, if Vassal States could never for some small part be International Persons?
Side by side with these facts stand, of course, other facts which show that for the most part the Vassal State, even if it has some small position of its own within the Family of Nations, is considered a mere portion of the Suzerain State. Thus all international treaties concluded by the Suzerain State are ipso facto concluded for the vassal, if an exception is not expressly mentioned or self-evident. Thus, again, war of the suzerain is ipso facto war of the vassal. Thus, thirdly, the suzerain bears within certain limits a responsibility for actions of the Vassal State.
Under these circumstances it is generally admitted that the conception of suzerainty lacks juridical precision, and experience teaches that Vassal States do not remain half-Sovereign for long. They either shake off suzerainty, as Roumania, Servia, and Montenegro did in 1878, and Bulgaria[140] did in 1908, or they lose their half-Sovereignty through annexation, as in the case of the South African Republic in 1901, or through merger, as when the half-Sovereign Seignory of Kniephausen in Germany merged in 1854 into its suzerain Oldenburg.
[140] As regards the position of Bulgaria while she was a Vassal State under Turkish suzerainty, see Holland, "The European Concert in the Eastern Question" (1885), pp. 277-307, and Nédjmidin, "Völkerrechtliche Entwicklung Bulgariens" (1908).
Vassal States of importance which are for some parts International Persons are, at present, Egypt,[141] and Crete.[142] They are both under Turkish suzerainty, although Egypt is actually under the administration of Great Britain. Samos,[143] which some writers consider a Vassal State under Turkish suzerainty, is not half-Sovereign, but enjoys autonomy to a vast degree.

XIV. (1907), pp. 405-416; Lamba in R.G. XVII. (1910), pp. 36-55. In the case of the "Charkieh," 1873, L.R. 4 Adm. and Eccl. 59, the Court refused to acknowledge the half-sovereignty of Egypt; see Phillimore, I. § 99.
