Second Peace Conference (1907) The Second Peace Conference convened at The Hague in 1907 as a follow-up to the 1899 First Hague Conference and sought to codify rules for armed conflict, maritime prize law, and arbitration mechanisms. Led by representatives from major powers such as the United Kingdom, German Empire, Russian Empire, United States, and France, the conference produced a set of multilateral instruments that influenced twentieth‑century international law and the conduct of World War I and later Geneva Conventions. The proceedings reflected tensions among imperialism, naval strategy debates exemplified by the Dreadnought era, and rivalries implicated in the Balkan Wars and Russo-Japanese War aftermath.

Background and context

The conference arose from diplomatic momentum created by the First Hague Conference and petitions from peace movements like the Permanent Court of Arbitration advocates and organizations such as the Interparliamentary Union and International Red Cross and Red Crescent Movement. Rising tensions after the Spanish–American War, Boxer Rebellion, and the Russo-Japanese War underscored the need to clarify laws governing sieges, bombardment, and neutral rights at sea established partly in the Declaration of Paris (1856) and contested during the Second Boer War. Naval developments involving Alfred Thayer Mahan-influenced doctrines and the naval arms race between Great Britain and the German Empire framed disputes over prize law, contraband, and blockades.

Participants and organization

Forty‑four states attended, including great powers and smaller states: representatives from the Austro-Hungarian Empire, Ottoman Empire, Italy, Japan, Belgium, Netherlands, Sweden, Norway, Portugal, Spain, Greece, Romania, Serbia, Bulgaria, Montenegro, Denmark, Switzerland, the United States of America, and numerous Latin American states such as Argentina, Brazil, and Chile. Delegations were often led by foreign ministers, ambassadors, and jurists linked to institutions like the Permanent Court of Arbitration and universities associated with scholars such as Lassa Oppenheim and Hans Kelsen. The conference formed committees on subjects including laws and customs of war, naval warfare, and the peaceful settlement of international disputes; procedural leadership included presidents and rapporteurs drawn from diplomatic corps stationed in The Hague and capitals like London, Berlin, Paris, and Washington, D.C..

Agenda and major issues

Key agenda items included revision of the 1899 conventions on land warfare, new rules on naval prize and blockade, protections for hospitals and ambulance personnel linked to the International Committee of the Red Cross, and mechanisms for arbitration and good offices modeled on the Permanent Court of Arbitration. Debates considered the status of "filtered contraband", rights of neutrals under blockade, bombardment of undefended places, and protections for cultural property influenced by earlier appeals from scholars and figures associated with the Society of Nations concept. Questions also touched on state consent for arbitration, compulsory jurisdiction as later sought in proposals akin to the Kellogg–Briand Pact, and the role of neutral powers such as Spain and Switzerland.

Negotiations and key outcomes

Negotiations were marked by sharp differences among the United Kingdom, French Republic, German Empire, and Russian Empire over maritime law; smaller states sought broader protections for neutrality and humanitarians like the International Committee of the Red Cross pressed for clearer protections. Compromises produced expanded regulations on the conduct of land warfare clarifying the treatment of protected persons and limitations on means of injuring the enemy, alongside detailed provisions on naval prize and contraband that reflected British concerns about freedom of the seas and German insistence on effective blockade rights. Diplomatic backchannels involved capitals in Saint Petersburg, Vienna, Rome, and Tokyo and legal drafting drew upon precedents from the Hague Conventions of 1899 and doctrines articulated by jurists associated with the Institut de Droit International.

Treaties and declarations adopted

The conference adopted a suite of instruments collectively known as the Hague Conventions of 1907, including conventions on the Laws and Customs of War on Land, the Opening of Hostilities, Bombardment by Naval Forces in Time of War, the Laying of Automatic Submarine Contact Mines, and Rights and Duties of Neutral Powers and Persons in Case of War on Land; additional conventions addressed maritime prize, hospital ships, and the establishment and functioning of the Permanent Court of Arbitration. Declarations included prohibitions on certain types of projectiles and recognition of protections for civilian and medical personnel; texts reflected input from jurists, naval officers, and humanitarian organizations and were registered with diplomatic archives in The Hague.

Impact and legacy

The 1907 instruments significantly shaped twentieth‑century international law and influenced legal arguments during World War I and World War II; drafters and later advocates cited the conventions in proceedings before tribunals connected to the Paris Peace Conference (1919) and emerging institutions that preceded the United Nations. The conventions bolstered the normative status of arbitration exemplified by the Permanent Court of Arbitration and informed later codification in the Geneva Conventions and the work of legal scholars at institutions such as the Hague Academy of International Law. Their limitations—especially enforcement gaps—helped motivate interwar debates over collective security at forums including the League of Nations.

Criticism and controversies

Contemporaneous critics argued the conference reflected great‑power bargaining that privileged imperial interests of the British Empire, French Republic, and German Empire and produced ambiguous rules exploited in subsequent conflicts; pacifists such as members of the Women’s International League for Peace and Freedom and activists from the Second International contended that codification without enforcement mechanisms was insufficient. Naval powers disputed prize law formulations while legal scholars debated customary law versus treaty obligations, with jurists from Russia and Japan sometimes dissenting. Postwar historians and international lawyers linked the conventions' shortcomings to failures in preventing large‑scale warfare, prompting continued efforts by actors in Washington, D.C., Geneva, and The Hague to strengthen international adjudication.
