The
Second Hague Conference, in 1907, resulted in conventions containing only few major advancements from the 1899 Convention. However, the meeting of major powers did prefigure later 20th-century attempts at international cooperation. The second conference was called at the suggestion of U.S. President
Theodore Roosevelt in 1904. It was postponed because of the
war between Russia and Japan. The
Second Peace Conference was held from 15 June to 18 October 1907. The intent of the conference was to expand upon the 1899 Hague Convention by modifying some parts and adding new topics; in particular, the 1907 conference had an increased focus on
naval warfare. The British attempted to secure the limitation of armaments, but these efforts were defeated by the other powers, led by Germany, which feared a British attempt to stop the growth of the German fleet. As Britain had
the world's largest navy, limits on naval expansion would preserve that dominant position. Germany also rejected proposals for compulsory arbitration. However, the conference did enlarge the machinery for voluntary arbitration and established conventions regulating the collection of debts, rules of war, and the rights and obligations of neutrals. The treaties, declarations, and final act of the Second Conference were signed on 18 October 1907; they entered into force on 26 January 1910. The 1907 Convention consists of thirteen treaties—of which twelve were ratified and entered into force—and one declaration: ; (I) Convention for the Pacific Settlement of International Disputes :This convention confirms and expands on Convention (I) of 1899. As of February 2017, this convention is in force for 102 states, and 116 states have ratified one or both of the 1907 Convention (I) and the 1899 Convention (I), which together are the founding documents of the
Permanent Court of Arbitration. ; (II) Convention respecting the Limitation of the Employment of Force for Recovery of Contract Debts : This convention requires debts between contracting parties to be settled by arbitration (as set out in Convention I) rather than war, unless the debtor refuses to negotiate or reneges on an agreed settlement. ; (III) Convention relative to the Opening of Hostilities :This convention sets out the accepted procedure for a state making a
declaration of war. It provides the basis on which, in international law,
war reparations may be demanded. and
Serbia were also signatories, but their successor
Yugoslavia was never a party. Some other territories shown as not being parties were bound as part of contracting parties, e.g.
Ukraine (Russia) and
Bohemia (Austria). ; (IV) Convention respecting the Laws and Customs of War on Land :This convention confirms, with minor modifications, the provisions of Convention (II) of 1899. All major powers ratified it. ; (V) Convention relative to the Rights and Duties of Neutral Powers and Persons in case of War on Land ; (VI) Convention relative to the Legal Position of Enemy Merchant Ships at the Start of Hostilities ; (VII) Convention relative to the Conversion of Merchant Ships into War-ships ; (VIII) Convention relative to the Laying of Automatic Submarine Contact Mines ; (IX) Convention concerning Bombardment by Naval Forces in Time of War ; (X) Convention for the Adaptation to Maritime Warfare of the Principles of the Geneva Convention (of 6 July 1906) :This convention updated Convention (III) of 1899 to reflect the amendments that had been made to the
1864 Geneva Convention. Convention (X) was ratified by all major states except Britain. It was subsequently superseded by the
Second Geneva Convention. ; (XI) Convention relative to Certain Restrictions with regard to the Exercise of the Right of Capture in Naval War ; (XII) Convention relative to the Establishment of an International Prize Court :This convention would have established the
International Prize Court for the resolution of conflicting claims relating to captured ships during wartime. It is the one convention that never came into force. It was ratified only by
Nicaragua. ; (XIII) Convention concerning the Rights and Duties of Neutral Powers in Naval War ; (XIV) Declaration Prohibiting the Discharge of Projectiles and Explosives from Balloons :This declaration extended the provisions of Declaration (IV,1) of 1899 to the close of the planned Third Peace Conference (which never took place). Among the major powers, this was ratified only by China, Britain, and the United States. At the same time an
International socialist Congress was standing in Stuttgart, in which the British delegate
Harry Quelch labelled the Hague Convention a "thieves' supper". German authorities were swift in expelling Quelch from the country for his remarks, an action which boosted British esteem in the eyes of their radical peers.
Participants The Brazilian delegation was led by
Ruy Barbosa, whose contributions are seen today by some analysts as essential for the defense of the principle of legal equality of nations. The British delegation included Sir
Edward Fry, Sir
Ernest Satow, the
11th Lord Reay (Donald James Mackay) and Sir
Henry Howard as delegates, and
Eyre Crowe as a technical delegate. The Russian delegation was led by
Friedrich Martens. The
Uruguayan delegation was led by
José Batlle y Ordóñez, a defender of the idea of compulsory arbitration. With
Louis Renault and
Léon Bourgeois,
Paul Henri d'Estournelles de Constant was a member of the French delegation for both the 1899 and 1907 delegations. He later won the
Nobel Peace Prize in 1909 for his efforts. The U.S. representative, with the rank of ambassador, was former
American Bar Association president
U. M. Rose. The main representative of the Chinese Empire was
Lu Zhengxiang, who would become Prime Minister of the Republic of China in 1912. Also in attendance on behalf of China was former U.S. Secretary of State John Watson Foster. China's main military representative was Colonel Ding Shiyuan(丁士源), whose suggestion regarding the need for a more specific legal definition of "war" was rejected by most of the Western participants. Though not negotiated in The Hague, the
Geneva Protocol to the Hague Conventions is considered an addition to the Conventions. Signed on 17 June 1925 and entering into force on 8 February 1928, its single article permanently bans the use of all forms of
chemical and
biological warfare in interstate armed conflicts. The protocol grew out of the increasing public outcry against chemical warfare following the use of
mustard gas and similar agents in
World War I, and fears that chemical and biological warfare could lead to horrific consequences in any future war. The protocol has since been augmented by the
Biological Weapons Convention (1972) and the
Chemical Weapons Convention (1993). ==Legacy==
