§ 47. The period after the Vienna Congress begins with the so-called Holy Alliance. Already on September 26, 1815, before the second Peace of Paris, the Emperors of Russia and Austria and the King of Prussia called this alliance into existence, the object of which was to make it a duty upon its members to apply the principles of Christian morality in the administration of the home affairs of their States as well as in the conduct of their international relations. After the Vienna Congress the sovereigns of almost all the European States had joined that alliance with the exception of England. George IV., at that time prince-regent only, did not join, because the Holy Alliance was an alliance not of the States, but of sovereigns, and therefore was concluded without the signatures of the respective responsible Ministers, whereas according to the English Constitution the signature of such a responsible Minister would have been necessary.

The Holy Alliance had not as such any importance for International Law, for it was a religious, moral, and political, but scarcely a legal alliance. But at the Congress of Aix-la-Chapelle in 1818, which the Emperors of Russia and Austria and the King of Prussia attended in person, and where it might be said that the principles of the Holy Alliance were practically applied, the Great Powers signed a Declaration,[43] in which they solemnly recognised the Law of Nations as the basis of all international relations, and in which they pledged themselves for all the future to act according to its rules. The leading principle of their politics was that of legitimacy,[44] as they endeavoured to preserve everywhere the old dynasties and to protect the sovereigns of the different countries against revolutionary movements of their subjects. This led, in fact, to a dangerous neglect of the principles of International Law regarding intervention. The Great Powers, with the exception of England, intervened constantly with the domestic affairs of the minor States in the interest of the legitimate dynasties and of an anti-liberal legislation. The Congresses at Troppau, 1820, Laibach, 1821, Verona, 1822, occupied themselves with a deliberation on such interventions.

The famous Monroe Doctrine (see below, § 139) owes its origin to that dangerous policy of the European Powers as regards intervention, although this doctrine embraces other points besides intervention. As from 1810 onwards the Spanish colonies in South America were falling off from the mother country and declaring their independence, and as Spain was, after the Vienna Congress, thinking of reconquering these States with the help of other Powers who upheld the principle of legitimacy, President Monroe delivered his message on December 2, 1823, which pointed out amongst other things, that the United States could not allow the interference of a European Power with the States of the American continent.

Different from the intervention of the Powers of the Holy Alliance in the interest of legitimacy were the two interventions in the interest of Greece and Belgium. England, France, and Russia intervened in 1827 in the struggle of Turkey with the Greeks, an intervention which led finally in 1830 to the independence of Greece. And the Great Powers of the time, namely, England, Austria, France, Prussia, and Russia, invited by the provisional Belgian Government, intervened in 1830 in the struggle of the Dutch with the Belgians and secured the formation of a separate Kingdom of Belgium.

It may be maintained that the establishment of Greece and Belgium inferred the breakdown of the Holy Alliance. But it was not till the year 1848 that this alliance was totally swept away through the disappearance of absolutism and the victory of the constitutional system in most States of Europe. Shortly afterwards, in 1852, Napoleon III., who adopted the principle of nationality,[45] became Emperor of France. Since he exercised preponderant influence in Europe, one may say that this principle of nationality superseded in European politics the principle of legitimacy.

The last event of this period is the Crimean War, which led to the Peace as well as to the Declaration of Paris in 1856. This war broke out in 1853 between Russia and Turkey. In 1854, England, France, and Sardinia joined Turkey, but the war continued nevertheless for another two years. Finally, however, Russia was defeated, a Congress assembled at Paris, where England, France, Austria, Russia, Sardinia, Turkey, and eventually Prussia, were represented, and peace was concluded in March 1856. In the Peace Treaty, Turkey is expressly received as a member into the Family of Nations. Of greater importance, however, is the celebrated Declaration of Paris regarding maritime International Law which was signed on April 16, 1856, by the delegates of the Powers that had taken part in the Congress. This declaration abolished privateering, recognised the rules that enemy goods on neutral vessels and that neutral goods on enemy vessels cannot be confiscated, and stipulated that a blockade in order to be binding must be effective. Together with the fact that at the end of the first quarter of the nineteenth century the principle of the freedom of the high seas[46] became universally recognised, the Declaration of Paris is a prominent landmark in the progress of the Law of Nations. The Powers that had not been represented at the Congress of Paris were invited to sign the Declaration afterwards, and the majority of the members of the Family of Nations did sign it before the end of the year 1856. The few States, such as the United States of America, Spain, Mexico, and others, which did not then sign,[47] have in practice since 1856 not acted in opposition to the Declaration, and one may therefore, perhaps, maintain that the Declaration of Paris has already become or will soon become universal International Law through custom. Spain and Mexico, however, signed the Declaration in 1907, as Japan had already done in 1886.

§ 48. The next period, the time from 1856 to 1874, is of prominent importance for the development of the Law of Nations. Under the aegis of the principle of nationality, Austria turns in 1867 into the dual monarchy of Austria-Hungary, and Italy as well as Germany becomes united. The unity of Italy rises out of the war of France and Sardinia against Austria in 1859, and Italy ranges henceforth among the Great Powers of Europe. The unity of Germany is the combined result of three wars: that of Austria and Prussia in 1864 against Denmark on account of Schleswig-Holstein, that of Prussia and Italy against Austria in 1866, and that of Prussia and the allied South German States against France in 1870. The defeat of France in 1870 had the consequence that Italy took possession of the Papal States, whereby the Pope disappeared from the number of governing sovereigns.

The United States of America rise through the successful termination of the Civil War in 1865 to the position of a Great Power. Several rules of maritime International Law owe their further development to this war. And the instructions concerning warfare on land, published in 1863 by the Government of the United States, represent the first step towards codification of the Laws of War. In 1864, the Geneva Convention for the amelioration of the condition of soldiers wounded in armies in the field is, on the initiation of Switzerland, concluded by nine States, and in time almost all civilised States became parties to it. In 1868, the Declaration of St. Petersburg, interdicting the employment in war of explosive balls below a certain weight, is signed by many States. Since Russia in 1870 had arbitrarily shaken off the restrictions of Article 11 of the Peace Treaty of Paris of 1856 neutralising the Black Sea, the Conference of London, which met in 1871 and was attended by the representatives of the Powers which were parties to the Peace of Paris of 1856, solemnly proclaimed "that it is an essential principle of the Law of Nations that no Power can liberate itself from the engagements of a treaty, or modify the stipulations thereof, unless with the consent of the contracting Powers by means of an amicable arrangement." The last event in this period is the Conference of Brussels of 1874 for the codification of the rules and usages of war on land. Although the signed code was never ratified, the Brussels Conference was nevertheless epoch-making, since it showed the readiness of the Powers to come to an understanding regarding such a code.

§ 49. After 1874 the principle of nationality continues to exercise its influence as before. Under its aegis takes place the partial decay of the Ottoman Empire. The refusal of Turkey to introduce reforms regarding the Balkan population led in 1877 to war between Turkey and Russia, which was ended in 1878 by the peace of San Stefano. As the conditions of this treaty would practically have done away with Turkey in Europe, England intervened and a European Congress assembled at Berlin in June 1878 which modified materially the conditions of the Peace of San Stefano. The chief results of the Berlin Congress are:—(1) Servia, Roumania, Montenegro become independent and Sovereign States; (2) Bulgaria becomes an independent principality under Turkish suzerainty; (3) the Turkish provinces of Bosnia and Herzegovina come under the administration of Austria-Hungary; (4) a new province under the name of Eastern Rumelia is created in Turkey and is to enjoy great local autonomy (according to an arrangement of the Conference of Constantinople in 1885-1886 a bond is created between Eastern Rumelia and Bulgaria by the appointment of the Prince of Bulgaria as governor of Eastern Rumelia); (5) free navigation on the Danube from the Iron Gates to its mouth in the Black Sea is proclaimed.

In 1889 Brazil becomes a Republic and a Federal State (the United States of Brazil). In the same year the first Pan-American Congress meets at Washington.

In 1897 Crete revolts against Turkey, war breaks out between Greece and Turkey, the Powers interfere, and peace is concluded at Constantinople. Crete becomes an autonomous half-Sovereign State under Turkish suzerainty with Prince George of Greece as governor, who, however, retires in 1906.

In the Far East war breaks out in 1894 between China and Japan, on account of Korea. China is defeated, and peace is concluded in 1895 at Shimonoseki.[48] Japan henceforth ranks as a Great Power. That she must now be considered a full member of the Family of Nations becomes apparent from the treaties concluded soon afterwards by her with other Powers for the purpose of abolishing their consular jurisdiction within the boundaries of Japan.

In America the United States intervene in 1898 in the revolt of Cuba against the motherland, whereby war breaks out between Spain and the United States. The defeat of Spain secures the independence of Cuba through the Peace of Paris[49] of 1898. The United States acquires Porto Rico and other Spanish West Indian Islands, and, further, the Philippine Islands, whereby she becomes a colonial Power.

An event of great importance during this period is the Congo Conference of Berlin, which took place in 1884-1885, and at which England, Germany, Austria-Hungary, Belgium, Denmark, Spain, the United States of America, France, Italy, Holland, Portugal, Russia, Sweden-Norway, and Turkey were represented. This conference stipulated freedom of commerce, interdiction of slave-trade, and neutralisation of the territories in the Congo district, and secured freedom of navigation on the rivers Congo and Niger. The so-called Congo Free State was recognised as a member of the Family of Nations.

A second fact of great importance during this period is the movement towards the conclusion of international agreements concerning matters of international administration. This movement finds expression in the establishment of numerous International Unions with special International Offices. Thus a Universal Telegraphic Union is established in 1875, a Universal Postal Union in 1878, a Union for the Protection of Industrial Property in 1883, a Union for the Protection of Works of Literature and Art in 1886, a Union for the Publication of Custom Tariffs in 1890. There were also concluded conventions concerning:—(1) Private International Law (1900 and 1902); (2) Railway transports and freights (1890); (3) the metric system (1875); (4) phylloxera epidemics (1878 and 1881); (5) cholera and plague epidemics (1893, 1896, &c.); (6) Monetary Unions (1865, 1878, 1885, 1892, 1893).

A third fact of great importance is that in this period a tendency arises to settle international conflicts more frequently than in former times by arbitration. Numerous arbitrations are actually taking place, and several treaties are concluded between different States stipulating the settlement by arbitration of all conflicts which might arise in future between the contracting parties.

The last fact of great importance which is epoch-making for this period is the Peace Conference of the Hague of 1899. This Conference produces, apart from three Declarations of minor importance, a Convention for the Pacific Settlement of International Conflicts, a Convention regarding the Laws and Customs of War on Land, and a Convention for the Adaptation to Maritime Warfare of the Principles of the Geneva Convention. It also formulates, among others, the three wishes (1) that a conference should in the near future regulate the rights and duties of neutrals, (2) that a future conference should contemplate the declaration of the inviolability of private property in naval warfare, (3) that a future conference should settle the question of the bombardment of ports, towns, and villages by naval forces.

§ 50. Soon after the Hague Peace Conference, in October 1899, war breaks out in South Africa between Great Britain and the two Boer Republics, which leads to the latter's subjugation at the end of 1901. The assassination on June 10, 1900, of the German Minister and the general attack on the foreign legations at Peking necessitate united action of the Powers against China for the purpose of vindicating this violation of the fundamental rules of the Laws of Nations. Friendly relations are, however, re-established with China on her submitting to the conditions enumerated in the Final Protocol of Peking,[50] signed on September 7, 1901. In December 1902 Great Britain, Germany, and Italy institute a blockade of the coast of Venezuela for the purpose of making her comply with their demands for the indemnification of their subjects wronged during civil wars in Venezuela, and the latter consents to pay indemnities to be settled by a mixed commission of diplomatists.[51] As, however, Powers other than those blockading likewise claim indemnities, the matter is referred to the Permanent Court of Arbitration at the Hague, which in 1904 gives its award[52] in favour of the blockading Powers. In February 1904 war breaks out between Japan and Russia on account of Manchuria and Korea. Russia is defeated, and peace is concluded through the mediation of the United States of America, on September 5, 1905, at Portsmouth.[53] Korea, now freed from the influence of Russia, places herself by the Treaty of Seoul[54] of November 17, 1905, under the protectorate of Japan. Five years later, however, by the Treaty of Seoul[55] of August 22, 1910, she merges entirely into Japan.

The Real Union between Norway and Sweden, which was established by the Vienna Congress in 1815, is peacefully dissolved by the Treaty of Karlstad[56] of October 26, 1905. Norway becomes a separate kingdom under Prince Charles of Denmark, who takes the name of Haakon VIII., and Great Britain, Germany, Russia, and France guarantee by the Treaty of Christiania[57] of November 2, 1907, the integrity of Norway on condition that she would not cede any part of her territory to any foreign Power.

The rivalry between France and Germany—the latter protesting against the position conceded to France in Morocco by the Anglo-French agreement signed at London on April 8, 1904—leads in January 1906 to the Conference of Algeciras, in which Great Britain, France, Germany, Belgium, Holland, Italy, Austria-Hungary, Portugal, Russia, Sweden, Spain, and the United States of America take part, and where on April 7, 1906, the General Act of the International Conference of Algeciras[58] is signed. This Act, which recognises, on the one hand, the independence and integrity of Morocco, and, on the other, equal commercial facilities for all nations in that country, contains:—(1) A declaration concerning the organisation of the Moroccan police; (2) regulations concerning the detection and suppression of the illicit trade in arms; (3) an Act of concession for a Moorish State Bank; (4) a declaration concerning an improved yield of the taxes and the creation of new sources of revenue; (5) regulations respecting customs and the suppression of fraud and smuggling; (6) a declaration concerning the public services and public works. But it would seem that this Act has not produced a condition of affairs of any permanency. Since, in 1911, internal disturbances in Morocco led to military action on the part of France and Spain, Germany, in July of the same year, sent a man-of-war to the port of Agadir. Thus the Moroccan question has been reopened, and fresh negotiations for its settlement are taking place between the Powers.[59]

Two events of importance occur in 1908. The first is the merging of the Congo Free State[60] into Belgium, which annexation is not as yet recognised by all the Powers. The other is the crisis in the Near East caused by the ascendency of the so-called Young Turks and the introduction of a constitution in Turkey. Simultaneously on October 5, 1908, Bulgaria declares herself independent, and Austria-Hungary proclaims her sovereignty over Bosnia and Herzegovina, which two Turkish provinces had been under her administration since 1878. This violation of the Treaty of Berlin considerably endangers the peace of the world, and an international conference is proposed for the purpose of reconsidering the settlement of the Near Eastern question. Austria-Hungary, however, does not consent to this, but prefers to negotiate with Turkey alone in the matter, and a Protocol is signed by the two Powers on February 26, 1909, according to which Turkey receives a substantial indemnity in money and other concessions. Austria-Hungary negotiates likewise with Montenegro alone, and consents to the modifications in Article 29 of the Treaty of Berlin concerning the harbour of Antivary, which is to be freed from Austria-Hungarian control and is henceforth to be open to warships of all nations. Whereupon the demand for an international conference is abandoned and the Powers notify on April 7, 1909, their consent to the abolition of Article 25 and the amendment of Article 29 of the Treaty of Berlin.[61]

In 1910 Portugal becomes a Republic; but the Powers, although they enter provisionally into communication with the de facto government, do not recognise the Republic until September 1911, after the National Assembly adopted the republican form of government.

In September 1911 war breaks out between Italy and Turkey, on account of the alleged maltreatment of Italian subjects in Tripoli.

International Law as a body of rules for the international conduct of States makes steady progress during this period. This is evidenced by congresses, conferences, and law-making treaties. Of conferences and congresses must be mentioned the second, third, and fourth Pan-American Congresses,[62] which take place at Mexico in 1901, at Rio in 1906, and at Buenos Ayres in 1910. Although the law-making treaties of these congresses have not found ratification, their importance cannot be denied. Further, in 1906 a conference assembles in Geneva for the purpose of revising the Geneva Convention of 1864 concerning the wounded in land warfare, and on July 6, 1906, the new Geneva[63] Convention is signed. Of the greatest importance, however, are the second Hague Peace Conference of 1907 and the Naval Conference of London of 1898-9.

The second Peace Conference assembles at the Hague on June 15, 1907. Whereas at the first there were only 26 States represented, 44 are represented at the second Peace Conference. The result of this Conference is contained in its Final Act,[64] which is signed on October 18, 1907, and embodies no fewer than thirteen law-making Conventions besides a declaration of minor importance. Of these Conventions, 1, 4, and 10 are mere revisions of Conventions agreed upon at the first Peace Conference of 1899, but the others are new and concern:—The employment of force for the recovery of contract debts (2); the commencement of hostilities (3); the rights and duties of neutrals in land warfare (5); the status of enemy merchant-ships at the outbreak of hostilities (6); the conversion of merchantmen into men-of-war (7); the laying of submarine mines (8); the bombardment by naval forces (9); restrictions of the right of capture in maritime war (11); the establishment of an International Prize Court (12); the rights and duties of neutrals in maritime war (13).

The Naval Conference of London assembles on December 4, 1908, for the purpose of discussing the possibility of creating a code of prize law without which the International Prize Court, agreed upon at the second Hague Peace Conference, could not be established, and produces the Declaration of London, signed on February 26, 1909. This Declaration contains 71 articles, and settles in nine chapters the law concerning:—(1) Blockade; (2) contraband; (3) un-neutral service; (4) destruction of neutral prizes; (5) transfer to a neutral flag; (6) enemy character; (7) convoy; (8) resistance to search; and (9) compensation. The Declaration is accompanied by a General Report on its stipulations which is intended to serve as an official commentary.

The movement which began in the last half of the nineteenth century towards the conclusion of international agreements concerning matters of international administration, develops favourably during this period. The following conventions are the outcome of this movement:—(1) Concerning the preservation of wild animals, birds, and fish in Africa (1900); (2) concerning international hydrographic and biological investigations in the North Sea (1901); (3) concerning protection of birds useful for agriculture (1902); (4) concerning the production of sugar (1902); (5) concerning the White Slave traffic (1904); (6) concerning the establishment of an International Agricultural Institute at Rome (1905); (7) concerning unification of the Pharmacopœial Formulas (1906); (8) concerning the prohibition of the use of white phosphorus (1906); (9) concerning the prohibition of night work for women (1906); (10) concerning the international circulation of motor vehicles (1909).

It is, lastly, of the greatest importance to mention that the so-called peace movement,[65] which aims at the settlement of all international disputes by arbitration or judicial decision of an International Court, gains considerable influence over the Governments and public opinion everywhere since the first Hague Peace Conference. A great number of arbitration treaties are agreed upon, and the Permanent Court of Arbitration established at the Hague gives its first award[66] in a case in 1902 and its ninth in 1911. The influence of these decisions upon the peaceful settlement of international differences generally is enormous, and it may confidently be expected that the third Hague Peace Conference will make arbitration obligatory for some of the matters which do not concern the vital interests, the honour, and the independence of the States. It is a hopeful sign that, whereas most of the existing arbitration treaties exempt conflicts which concern the vital interests, the honour, and the independence, Argentina and Chili in 1902, Denmark and Holland in 1903, Denmark and Italy in 1905, Denmark and Portugal in 1907, Argentina and Italy in 1907, the Central American Republics of Costa Rica, Guatemala, Honduras, Nicaragua, and San Salvador in 1907, Italy and Holland in 1907, entered into general arbitration treaties according to which all differences, without any exception, shall be settled by arbitration.[67]

§ 51. It is the task of history, not only to show how things have grown in the past, but also to extract a moral for the future out of the events of the past. Six morals can be said to be deduced from the history of the development of the Law of Nations:

(1) The first and principal moral is that a Law of Nations can exist only if there be an equilibrium, a balance of power, between the members of the Family of Nations. If the Powers cannot keep one another in check, no rules of law will have any force, since an over-powerful State will naturally try to act according to discretion and disobey the law. As there is not and never can be a central political authority above the Sovereign States that could enforce the rules of the Law of Nations, a balance of power must prevent any member of the Family of Nations from becoming omnipotent. The history of the times of Louis XIV. and Napoleon I. shows clearly the soundness of this principle.[68]

(2) The second moral is that International Law can develop progressively only when international politics, especially intervention, are made on the basis of real State interests. Dynastic wars belong to the past, as do interventions in favour of legitimacy. It is neither to be feared, nor to be hoped, that they should occur again in the future. But if they did, they would hamper the development of the Law of Nations in the future as they have done in the past.

(3) The third moral is that the principle of nationality is of such force that it is fruitless to try to stop its victory. Wherever a community of many millions of individuals, who are bound together by the same blood, language, and interests, become so powerful that they think it necessary to have a State of their own, in which they can live according to their own ideals and can build up a national civilisation, they will certainly get that State sooner or later. What international politics can, and should, do is to enforce the rule that minorities of individuals of another race shall not be outside the law, but shall be treated on equal terms with the majority. States embracing a population of several nationalities can exist and will always exist, as many examples show.

(4) The fourth moral is that every progress in the development of International Law wants due time to ripen. Although one must hope that the time will come when war will entirely disappear, there is no possibility of seeing this hope realised in our time. The first necessities of an eternal peace are that the surface of the earth should be shared between States of the same standard of civilisation, and that the moral ideas of the governing classes in all the States of the world should undergo such an alteration and progressive development as would create the conviction that arbitral awards and decisions of courts of justice are alone adequate means for the settlement of international differences. Eternal peace is an ideal, and in the very term "ideal" is involved the conviction of the impossibility of its realisation in the present, although it is a duty to aim constantly at such realisation. The Permanent Court of Arbitration at the Hague, now established by the Hague Peace Conference of 1899, is an institution that can bring us nearer to such realisation than ever could have been hoped. And codification of parts of the Law of Nations, following the codification of the rules regarding land warfare and the codification comprised in the Declaration of London, will in due time arrive, and will make the legal basis of international intercourse firmer, broader, and more manifest than before.[69]

(5) The fifth moral is that the progress of International Law depends to a great extent upon whether the legal school of International Jurists prevails over the diplomatic school.[70] The legal school desires International Law to develop more or less on the lines of Municipal Law, aiming at the codification of firm, decisive, and unequivocal rules of International Law, and working for the establishment of international Courts for the purpose of the administration of international justice. The diplomatic school, on the other hand, considers International Law to be, and prefers it to remain, rather a body of elastic principles than of firm and precise rules. The diplomatic school opposes the establishment of international Courts because it considers diplomatic settlement of international disputes, and failing this arbitration, preferable to international administration of justice by international Courts composed of permanently appointed judges. There is, however, no doubt that international Courts are urgently needed, and that the rules of International Law require now such an authoritative interpretation and administration as only an international Court can supply.

(6) The sixth, and last, moral is that the progressive development of International Law depends chiefly upon the standard of public morality on the one hand, and, on the other, upon economic interests. The higher the standard of public morality rises, the more will International Law progress. And the more important international economic interests grow, the more International Law will grow. For, looked upon from a certain stand-point, International Law is, just like Municipal Law, a product of moral and of economic factors, and at the same time the basis for a favourable development of moral and economic interests. This being an indisputable fact, it may, therefore, fearlessly be maintained that an immeasurable progress is guaranteed to International Law, since there are eternal moral and economic factors working in its favour.

§ 52. The science of the modern Law of Nations commences from Grotius's work, "De Jure Belli ac Pacis libri III.," because in it a fairly complete system of International Law was for the first time built up as an independent branch of the science of law. But there were many writers before Grotius who wrote on special parts of the Law of Nations. They are therefore commonly called "Forerunners of Grotius." The most important of these forerunners are the following: (1) Legnano, Professor of Law in the University of Bologna, who wrote in 1360 his book "De bello, de represaliis, et de duello," which was, however, not printed before 1477; (2) Belli, an Italian jurist and statesman, who published in 1563 his book, "De re militari et de bello"; (3) Brunus, a German jurist, who published in 1548 his book, "De legationibus"; (4) Victoria, Professor in the University of Salamanca, who published in 1557 his "Relectiones theologicae,"[71] which partly deals with the Law of War; (5) Ayala, of Spanish descent but born in Antwerp, a military judge in the army of Alexandro Farnese, the Prince of Parma. He published in 1582 his book, "De jure et officiis bellicis et disciplina militari"; (6) Suarez, a Spanish Jesuit and Professor at Coimbra, who published in 1612 his "Tractatus de legibus et de legislatore," in which (II. c. 19, n. 8) for the first time the attempt is made to found a law between the States on the fact that they form a community of States; (7) Gentilis (1552-1608), an Italian jurist, who became Professor of Civil Law in Oxford. He published in 1585 his work, "De legationibus," in 1588 and 1589 his "Commentationes de jure belli," and in 1598 an enlarged work on the same matter under the title "De jure belli libri tres."[72] His "Advocatio Hispanica" was edited, after his death, in 1613 by his brother Scipio. Gentilis's book "De jure belli" supplies, as Professor Holland shows, the model and the framework of the first and third book of Grotius's "De Jure Belli ac Pacis." "The first step"—Holland rightly says—"towards making International Law what it is was taken, not by Grotius, but by Gentilis."
