In 1906, the 1864 Geneva Convention was revised for the first time. One year later, the Hague Convention X, adopted at the Second International Peace Conference in The Hague, extended the scope of the Geneva Convention to naval warfare. Shortly before the beginning of the First World War in 1914, 50 years after the foundation of the ICRC and the adoption of the first Geneva Convention, there were already 45 national relief societies throughout the world. The movement had extended itself beyond Europe and North America to Central and South America (Argentine Republic, the United States of Brazil, the Republic of Chile, the Republic of Cuba, the United Mexican States, the Republic of Peru, the Republic of El Salvador, the Oriental Republic of Uruguay, the United States of Venezuela), Asia (the Republic of China, the Empire of Japan and the Kingdom of Siam), and Africa (Union of South Africa).
