The former Papal States.

§ 104. When the Law of Nations began to grow up among the States of Christendom, the Pope was the monarch of one of those States—namely, the so-called Papal States. This State owed its existence to Pepin-le-Bref and his son Charlemagne, who established it in gratitude to the Popes Stephen III. and Adrian I., who crowned them as Kings of the Franks. It remained in the hands of the Popes till 1798, when it became a republic for about three years. In 1801 the former order of things was re-established, but in 1809 it became a part of the Napoleonic Empire. In 1814 it was re-established, and remained in existence till 1870, when it was annexed to the Kingdom of Italy. Throughout the existence of the Papal States, the Popes were monarchs and, as such, equals of all other monarchs. Their position was, however, even then anomalous, as their influence and the privileges granted to them by the different States were due, not alone to their being monarchs of a State, but to their being the head of the Roman Catholic Church. But this anomaly did not create any real difficulty, since the privileges granted to the Popes existed within the province of precedence only.

The Italian Law of Guaranty.

§ 105. When, in 1870, Italy annexed the Papal States and made Rome her capital, she had to undertake the task of creating a position for the Holy See and the Pope which was consonant with the importance of the latter to the Roman Catholic Church. It seemed impossible that the Pope should become an ordinary Italian subject and that the Holy See should be an institution under the territorial supremacy of Italy. For many reasons no alteration was desirable in the administration by the Holy See of the affairs of the Roman Catholic Church or in the position of the Pope as the inviolable head of that Church. To meet the case the Italian Parliament passed an Act regarding the guaranties granted to the Pope and the Holy See, which is commonly called the "Law of Guaranty." According to this the position of the Pope and the Holy See is in Italy as follows:—

The person of the Pope is sacred and inviolable (article 1), although he is subjected to the Civil Courts of Italy.[173] An offence against his person is to be punished in the same way as an offence against the King of Italy (article 2). He enjoys all the honours of a sovereign, retains the privileges of precedence conceded to him by Roman Catholic monarchs, has the right to keep an armed body-guard of the same strength as before the annexation for the safety of his person and of his palaces (article 3), and receives an allowance of 3,225,000 francs (article 4). The Vatican, the seat of the Holy See, and the palaces where a conclave for the election of a new Pope or where an Oecumenical Council meets, are inviolable, and no Italian official is allowed to enter them without consent of the Holy See (articles 5-8). The Pope is absolutely free in performing all the functions connected with his mission as head of the Roman Catholic Church, and so are his officials (articles 9 and 10). The Pope has the right to send and to receive envoys, who enjoy all the privileges of the diplomatic envoys sent and received by Italy (article 11). The freedom of communication between the Pope and the entire Roman Catholic world is recognised, and the Pope has therefore the right to a post and telegraph office of his own in the Vatican or any other place of residence and to appoint his own post-office clerks (article 12). And, lastly, the colleges and other institutions of the Pope for the education of priests in Rome and the environments remain under his exclusive supervision, without any interference on the part of the Italian authorities.

[173] See Bonfils, No. 379.

No Pope has as yet recognised this Italian Law of Guaranty, nor had foreign States an opportunity of giving their express consent to the position of the Pope in Italy created by that law. But practically foreign States as well as the Popes themselves, although the latter have never ceased to protest against the condition of things created by the annexation of the Papal States, have made use of the provisions[174] of that law. Several foreign States send side by side with their diplomatic envoys accredited to Italy special envoys to the Pope, and the latter sends envoys to several foreign States.

[174] But the Popes have hitherto never accepted the allowance provided by the Law of Guaranty.

International position of the Holy See and the Pope.

§ 106. The Law of Guaranty is not International but Italian Municipal Law, and the members of the Family of Nations have hitherto not made any special arrangements with regard to the International position of the Holy See and the Pope. And, further, there can be no doubt that since the extinction of the Papal States the Pope is no longer a monarch whose sovereignty is derived from his position as the head of a State. For these reasons many writers[175] maintain that the Holy See and the Pope have no longer any international position whatever according to the Law of Nations, since States only and exclusively are International Persons. But if the facts of international life and the actual condition of things in every-day practice are taken into consideration, this opinion has no basis to stand upon. Although the Holy See is not a State, the envoys sent by her to foreign States are treated by the latter on the same footing with diplomatic envoys as regards exterritoriality, inviolability, and ceremonial privileges, and those foreign States which send envoys to the Holy See claim for them from Italy all the privileges and the position of diplomatic envoys. Further, although the Pope is no longer the head of a State, the privileges due to the head of a monarchical State are still granted to him by foreign States. Of course, through this treatment the Holy See does not acquire the character of an International Person, nor does the Pope thereby acquire the character of a head of a monarchical State. But for some points the Holy See is actually treated as though she were an International Person, and the Pope is treated actually in every point as though he were the head of a monarchical State. It must therefore be maintained that by custom, by tacit consent of the members of the Family of Nations, the Holy See has a quasi international position. This position allows her to claim against all the States treatment on some points as though she were an International Person, and further to claim treatment of the Pope in every point as though he were the head of a monarchical State. But it must be emphasised that, although the envoys sent and received by the Holy See must be treated as diplomatic envoys,[176] they are not such in fact, for they are not agents for international affairs of States, but exclusively agents for the affairs of the Roman Catholic Church. And it must further be emphasised that the Holy See cannot conclude international treaties or claim a vote at international congresses and conferences. The so-called Concordats—that is, treaties between the Holy See and States with regard to matters of the Roman Catholic Church—are not international treaties, although analogous treatment is usually given to them. Even formerly, when the Pope was the head of a State, such Concordats were not concluded with the Papal States, but with the Holy See and the Pope as representatives of the Roman Catholic Church.
