The PCA was established by the Convention for the Pacific Settlement of International Disputes, concluded at The Hague in 1899 during the first Hague Peace Conference. The Conference was convened at the initiative of Czar Nicolas II of Russia "with the object of seeking the most objective means of ensuring to all peoples the benefits of a real and lasting peace, and above all, of limiting the progressive development of existing armaments." The most concrete achievement of the Conference was the establishment of the PCA: the first global mechanism for the settlement of disputes between states. The 1899 Convention was revised at the second Hague Peace Conference in 1907.




To celebrate the 100th anniversary of the 1907 Hague Peace Conference and the 1907 Convention for the Pacific Settlement of International Disputes, a commemorative meeting of the PCA’s Administrative Council was held for PCA member states on October 18, 2007.
