Proceedings of the fifth American Peace Congress held in San Francisco, California, October 10-13, 1915 : as the sixth and last congress of the Committee of one hundred (appointed by the Federal Council of the Churches of Christ in America to have charge of the religious activities during the Panama-Pacific International Exposition) and under the auspices of the Church Peace Union--the American Peace Society, assisted by the American League to limit armaments--the American Peace Centenary Committee--the League to enforce peace--the San Francisco Federated Peace Committee for 1915, and the Woman's Peace Party.

Proceedings of a conference held in San Francisco, California, October 10-13, 1915, including over twenty speeches on the subject of securing world peace. The stated purpose of its chief sponsor, the American Peace Society, was to "promote permanent international peace through justice; and to advance in every proper way the general use of conciliation, arbitration, judicial methods, and other peaceful means of avoiding and adjusting differences among nations, to the end that right shall rule might in a law-governed world." The APS was instrumental in bringing many peace congresses to The Hague, beginning in 1843; the Pan American Congress (out of which grew the Pan American Union); and to the United States from 1907 to 1915. A coalition with other peace societies was shattered by World War I (which the APS endorsed), and by the postwar debate over the League of Nations.
