After publishing his foundational text in 1862, progress came quickly for Dunant and his efforts to create a permanent relief society and International Humanitarian Law. The embryonic formation of the International Committee of the Red Cross had begun to take shape in 1863 when the private Geneva Society of Public Welfare created a permanent sub-committee called “The International Committee for Aid to Wounded in Situations of War”; composed of five Geneva citizens, this committee endorsed Dunant's vision to legally neutralize medical personnel responding to wounded soldiers. The constitutive conference of this committee in October 1863 created the statutory foundation of the International Committee of the Red Cross in their resolutions regarding national societies, caring for the wounded, their symbol, and most importantly the indispensable neutrality of ambulances, hospitals, medical personnel and the wounded themselves. Beyond this, in order to solidify humanitarian practice, the Geneva Society of Public Welfare hosted a convention between 8 and 22 August 1864 at the Geneva Town Hall with 16 diverse States present, including many governments of Europe, the Ottoman Empire, the United States of America (USA), Brazil and Mexico. This diplomatic conference was exceptional, not due to the number or status of its attendees but rather because of its very raison d'être. Unlike many diplomatic conferences before it, this conference's purpose was not to reach a settlement after a conflict nor to mediate between opposing interests; indeed this conference was to lay down rules for the future of conflict with aims to protect medical services and those wounded in battle.
