Second Hague Conference The Second Hague Conference was an international diplomatic assembly held in The Hague from May to July 1907 that produced a comprehensive set of multilateral instruments on the law of armed conflict, arbitration, and neutrality. Convened following the earlier First Hague Conference (1899), the gathering assembled representatives from the great powers and numerous smaller states to revise and extend preexisting treaties, harmonize rules on land and naval warfare, and establish procedures for compulsory arbitration and diplomatic procedure. The conference's negotiations involved prominent statesmen, jurists, and military figures and yielded the Hague Conventions of 1907, which influenced jurisprudence at The International Court of Justice, Permanent Court of Arbitration, and later treaties.

Background and Preludes

The conference arose after the Russo-Japanese War and amid tensions among the British Empire, German Empire, French Third Republic, Austro-Hungarian Empire, and the Russian Empire. Pressure from pacifist movements including the International Peace Bureau and legalists such as Édouard Descamps accompanied strategic concerns voiced by diplomats like Léon Bourgeois and T. E. Holland. The successes and limitations of the 1899 instruments, the experience of the Second Boer War, and naval competition involving the Royal Navy and Imperial German Navy spurred proposals to clarify rules on bombardment, neutral rights, and contraband. The Ottoman Empire, United States of America, Kingdom of Italy, and smaller European and non-European states sought codification to reduce ambiguity between customary practice and treaty law.

Participants and Diplomatic Preparations

Delegations included ministers and legal advisers from major capitals: representatives from the United Kingdom of Great Britain and Ireland, German Empire, Russian Empire, French Third Republic, Austro-Hungarian Empire, Kingdom of Italy, and the United States of America, alongside envoys of the Kingdom of Belgium, Kingdom of the Netherlands, Empire of Japan, Kingdom of Spain, Kingdom of Sweden and Norway, Kingdom of Denmark, Swiss Confederation, Ottoman Empire, Empire of Brazil, Argentine Republic, Republic of Chile, Republic of Paraguay, and others. Legal luminaries such as Friedrich Martens and delegates from the Permanent Court of Arbitration participated, while naval officers from the Royal Navy, Imperial German Navy, and Imperial Russian Navy advised on maritime law. Preparations in capitals involved briefs from foreign ministries, parliamentary committees like the British Parliament's Foreign Office advisers, and academic commentaries by jurists at institutions such as University of Paris and Humboldt University of Berlin.

Key Negotiations and Diplomatic Issues

Major debates concerned the laws and customs of war on land, the rights and duties of neutral powers and persons, and measures of naval warfare including blockade, contraband, and the scope of prize courts. Delegations argued over revisions to the 1899 regulations on bombardment, protections for cultural property proposed by conservationists associated with Camille Jullian and legal theorists, and the extension of compulsory arbitration advocated by delegates aligned with Léon Bourgeois and members sympathetic to the Inter-Parliamentary Union. The United States of America delegation, led by figures like Elihu Root, pressed for arbitration mechanisms; the German Empire and Austro-Hungarian Empire negotiated clauses on neutrality and siege. Disputes involved the Ottoman Empire on territorial issues, Japan on naval contraband, and Latin American delegations seeking assurances through provisions affirming sovereign equality.

Decisions and Agreements

The conference produced thirteen conventions and three declarations, collectively known as the Hague Conventions of 1907. Key instruments included revisions to the Convention respecting the Laws and Customs of War on Land, new conventions on the rights and duties of neutral powers on land and sea, and rules concerning the opening of hostilities and bombardment. The conference adopted regulations on prize courts and blockade affecting the Royal Navy and other fleets, plus a declaration concerning the launching of projectiles and explosives from balloons. Several states ratified protocols to extend compulsory arbitration and accepted procedures strengthening the Permanent Court of Arbitration. Though not all delegations agreed to every clause, the majority endorsed a framework that clarified obligations for belligerents and neutrals and strengthened legal procedures for dispute settlement.

Implementation and Immediate Aftermath

Following signature, ratification processes unfolded in national legislatures including the Reichstag (German Empire), the Parliament of the United Kingdom, the French Chamber of Deputies, and the United States Senate. Several disputes in the subsequent decade referenced the 1907 instruments in diplomatic protests and legal pleadings before bodies like the Permanent Court of Arbitration. Naval powers adjusted rules of engagement and prize procedures in light of the new conventions; the Royal Navy and Imperial German Navy incorporated aspects into operational manuals. However, the outbreak of First World War within seven years exposed limits of compliance, as belligerents invoked military necessity and produced divergent interpretations, particularly over blockade, submarine warfare involving the Kaiserliche Marine, and aerial bombardment.

Legacy and Historical Significance

The 1907 agreements left a durable codification that shaped twentieth-century international humanitarian law and the jurisprudence of The International Court of Justice and ad hoc tribunals. Scholars in institutions such as Harvard University, Oxford University, and Universidad Complutense de Madrid study the conventions for their influence on later instruments including the Geneva Conventions and the Kellogg–Briand Pact. The conference advanced procedures in arbitration that informed the development of peaceful dispute resolution mechanisms in organizations like the League of Nations and later the United Nations. Despite breaches during subsequent conflicts, the conventions provided legal benchmarks invoked in postwar trials, reparations negotiations, and state practice shaping customary international law.
