Laws of War (1907) The Laws of War (1907) refer to the multilateral treaties finalized at the Second Hague Conference in 1907 and related instruments from the First Hague Conference in 1899, consolidating customary and treaty law on conduct in armed conflict. They were negotiated by delegations from major and smaller states including the British Empire, German Empire, Russian Empire, French Third Republic, United States of America, and Empire of Japan, creating instruments influential for later instruments such as the Geneva Conventions and shaping jurisprudence at tribunals like the Nuremberg Trials and the International Court of Justice.

Background and Negotiation

Negotiations grew from initiatives by Tsar Nicholas II convening the First Hague Conference and later the Second Hague Conference where delegates from United Kingdom, German Empire, Russian Empire, France, United States of America, Japan and other states debated rules influenced by prior codifications such as the Lieber Code and public campaigns by figures like Bertha von Suttner, Eleanor Roosevelt-era advocates, and organizations including the International Committee of the Red Cross and the Institut de Droit International. Representatives from empires and smaller polities—Austria-Hungary, Ottoman Empire, Belgium, Netherlands—contested issues including the status of sieges at Siege of Port Arthur, naval blockades examined after the Spanish–American War, and new technologies showcased by Heinrich Hertz-era developments. Diplomatic negotiation drew on precedent from the Convention for the Amelioration of the Condition of the Wounded and Sick in Armies in the Field and the work of jurists such as Emmerich de Vattel-inspired scholars and delegates from the Hague Peace Conferences.

Key Conventions and Provisions

The 1907 instruments included distinct conventions: the Convention on the Opening of Hostilities, the Convention respecting the Laws and Customs of War on Land (Hague IV), the Convention with respect to the Rights and Duties of Neutral Powers and Persons in case of War on Land (Hague V), the Convention relative to the Laying of Automatic Submarine Contact Mines, the Convention on the Conversion of Merchant Ships into War-Ships, and several naval conventions addressing bombardment and blockades. Hague IV incorporated protections for combatants and non-combatants comparable to provisions earlier in the Geneva Convention (1864), regulated siege warfare after conflicts like the Franco-Prussian War, and restricted use of projectiles from sieges reminiscent of the Siege of Port Arthur and lessons learned in the Russo-Japanese War (1904–1905). Naval conventions—responding to incidents such as the Battle of Tsushima and concerns raised by the Royal Navy and Imperial German Navy—addressed submarine and mine warfare, contraband lists debated in the Baltimore crisis context, and rights of neutral states exemplified by Netherlands practice.

Principles and Legal Doctrine

Doctrinally, the 1907 instruments emphasized principles of distinction, proportionality, and military necessity as applied by jurists influenced by Willem van Eysinga and scholars of the Institut de Droit International. The conventions articulated obligations for occupying powers drawing on precedents from the Napoleonic Wars and rulings considered by the Permanent Court of Arbitration. Neutrality rules reflected balanced interests of littoral states such as the Kingdom of Sweden and Kingdom of Norway, while obligations for treatment of prisoners echoed customs consolidated in the Lieber Code and later elaborated at the Hague Tribunal in several postwar arbitrations. The legal status of new technologies, including naval mines and armored warfare, was treated within the framework of existing customary norms debated by delegations from United Kingdom, German Empire, Ottoman Empire, and Italy.

Implementation and Enforcement

Implementation relied on state practice and domestic incorporation by parliaments of signatory states such as the Reichstag (German Empire), the Parliament of the United Kingdom, and the United States Congress. Enforcement mechanisms were limited to inter-state diplomacy, reprisals, and adjudication by venues such as the Permanent Court of Arbitration and later litigation before the International Court of Justice. During World War I, belligerent conduct prompted disputes over compliance, leading to postwar prosecutions at ad hoc courts and influencing the Treaty of Versailles provisions. The conventions' limitations became apparent in enforcement episodes including controversies over unrestricted submarine warfare prosecuted in diplomatic protests by United States of America and disputes adjudicated in the Paris Peace Conference (1919–1920).

Impact on Military Practice and International Law

The 1907 conventions shaped doctrine adopted by staffs of the British Expeditionary Force, the German General Staff, the Imperial Russian Army, and navies such as the Royal Navy and Imperial Japanese Navy, influencing manuals and the codification of rules of engagement used in the Second Boer War aftermath. They provided a template for the Geneva Conventions of 1949, informed jurisprudence at the Nuremberg Trials and the International Criminal Tribunal for the former Yugoslavia, and were cited in arbitral proceedings involving the Island of Palmas case and disputes resolved by the Permanent Court of Arbitration. Scholarly work by figures such as Hersch Lauterpacht and Lassa Oppenheim traced doctrinal evolution from Hague texts to modern humanitarian law as applied in tribunals and national courts including rulings by the High Court of Australia and the Supreme Court of the United States.

Criticisms and Limitations

Critics from the League of Nations era onward—including jurists associated with Roscoe Pound-inspired realism and advocates in the International Committee of the Red Cross—argued the conventions were incomplete regarding aerial warfare, colonial conflicts exemplified by campaigns in German South-West Africa and Belgian Congo, and lacked robust enforcement against great powers. Debates at the Washington Naval Conference and in interwar legal scholarship noted ambiguities exploited by states such as Germany and Austria-Hungary during World War I, and scholars connected limitations to the failure to prevent atrocities later addressed by the Geneva Conventions and post-World War II tribunals. Despite critiques, the 1907 corpus remains a foundational source cited in cases before the International Court of Justice and doctrine of international humanitarian law development.
