The International Committee of the Red Cross (ICRC) Library was first created at the initiative of the ICRC's co-founder and president, Gustave Moynier. By the end of the nineteenth century, it had become a specialized documentation centre with comprehensive collections on the International Red Cross and Red Crescent Movement, international humanitarian law (IHL) and relief to war victims, keeping track of the latest legal debates and technological innovations in the fields related to the ICRC's activities. The publications collected by the Library until the end of the First World War form a rich collection of almost 4,000 documents now known as the ancien fonds, the Library's Heritage Collection.

Direct witness to the birth of an international humanitarian movement and of IHL, the Heritage Collection contains the era's most important publications related to the development of humanitarian action for war victims, from the first edition of Henry Dunant's groundbreaking Un souvenir de Solférino to the first mission reports of ICRC delegates and the handwritten minutes of the Diplomatic Conference that led to the adoption of the 1864 Geneva Convention. This article looks at the way this unique collection of documents retraces the history of the ICRC during its first decades of existence and documents its original preoccupations and operations, highlighting the most noteworthy items of the Collection along the way.

The early years of the Review, then called the Bulletin International des Sociétés de la Croix-Rouge, provide numerous insights into the International Committee of the Red Cross (ICRC), which edited the journal. Since the ICRC was very small in those days and without support staff, one learns a great deal, especially about Gustave Moynier, who led the organization and carried out most of the editing duties at the Bulletin. The reader can trace the role of religious and other motivations, attitudes toward colonialism, the evolving nature of the International Red Cross and Red Crescent Movement and the ICRC's place therein, and complex relations with States. This early era, as richly recorded in the journal, stimulates a number of questions about further research into ICRC and Red Cross history.

The trauma of coming face to face with the horrors of a battlefield and witnessing first-hand the abandonment of the war-wounded led Henry Dunant to two ingenious concepts: the creation of permanent volunteer relief societies and the adoption of a treaty to protect wounded soldiers and all who endeavour to come to their aid. On the initiative of Gustave Moynier, a committee was established in Geneva to implement Dunant's proposals. That committee – which soon took the name ‘International Committee of the Red Cross’ (ICRC) – convened two international conferences, the first of which laid the foundation for the future relief societies while the second adopted the initial Geneva Convention. This article considers the circumstances that led to the founding of the ICRC and then to that of the International Red Cross and Red Crescent Movement, starting with Solferino and culminating in the adoption of the Geneva Convention.
