International Committee of the Red Cross was awarded the Nobel Peace Prize in 1922, appointed two delegates from the ICRC as his deputies. A year before the end of the war, the ICRC received the 1917 Nobel Peace Prize for its outstanding wartime work. It was the only Nobel Peace Prize awarded in the period from 1914 to 1918. In 1923, the Committee adopted a change in its policy regarding the selection of new members. Until then, only citizens from the city of Geneva could serve in the Committee. This limitation was expanded to include Swiss citizens. As a direct consequence of World War I, an
International Committee of the Red Cross during an armed conflict was adopted by the International Red Cross Conference. Unfortunately, most governments had little interest in implementing this convention, and it was thus prevented from entering into force before the beginning of World War II. In the Interwar period, Bolivia and Paraguay were disputing possession of the Gran Chaco - a desert region between the two countries. The dispute escalated into a full-scale conflict in 1932. During the war the ICRC visited 18,000 Bolivian prisoners of war and 2,500 Paraguayan detainees. With the help of the ICRC both countries made improvements to the conditions of the detainees.
