The Geneva Convention of 1864 for the Amelioration of the Condition of the Wounded and Sick of Armies in the Field is adopted by 12 nations meeting in Geneva.
The agreement, advocated by Swiss humanitarian Jean-Henri Dunant, called for nonpartisan care to the sick and wounded in times of war, and provided for the neutrality of medical personnel.
It also proposed the use of an international emblem to mark medical personnel and supplies.
In honour of Dunant’s nationality, a red cross on a white background–the Swiss flag in reverse–was chosen. In 1901, Dunant was awarded the first Nobel Peace Prize.
