Under the leadership of Henry Dunant and the International Committee of the Red Cross, twelve European states signed the First Geneva Convention, establishing rules for the protection of victims of armed conflict.

Henry Dunant, also known as Henri Dunant, was a Swiss humanitarian, businessman, social activist, and co-founder of the Red Cross. His humanitarian efforts won him the first Nobel Peace Prize in 1901.

The International Committee of the Red Cross (ICRC) is a humanitarian organization based in Geneva, Switzerland, and is a three-time Nobel Prize laureate. The organization has played an instrumental role in the development of rules of war and promoting humanitarian norms.

The First Geneva Convention, officially the Convention for the Amelioration of the Condition of the Wounded in Armies in the Field, held on 22 August 1864, is the first of four treaties of the Geneva Conventions. It defines "the basis on which rest the rules of international law for the protection of the victims of armed conflicts."
