The previous proposal led to the creation of the Red Cross in Geneva. The latter culminated in the Geneva Convention in 1864, the first codified international treaty covering sick and wounded soldiers on the battlefield. On August 22, 1864, the Swiss government invited the governments of all European countries as well as the United States, Brazil and Mexico to an official diplomatic conference. Sixteen countries sent 26 delegates to Geneva. On 22 August 1864, the Conference adopted the first Geneva Convention „to improve the condition of the wounded in the armies on the ground.“ Representatives of 12 states and kingdoms signed the Convention: On October 20, 1868, the first unsuccessful attempt to extend the 1864 treaty was made. „Additional articles on the state of the wounded at war“ attempted to clarify some of the rules of the 1864 convention and extend them to the command of maritime warfare. The articles were signed, but ratified only by the Netherlands and the United States of America.  The Netherlands subsequently withdrew its ratification.  The protection of the victims of maritime war was to be carried out at a later date by the Third Hague Convention of 1899 and the 10th Hague Convention of 1907.  In February 1945, the ICRC therefore announced to governments and national Red Cross societies its intention to revise the existing Geneva Conventions and adopt new conventions, while questioning whether there was still room for humanitarian rules in a period of total war. The Geneva Convention was a series of international diplomatic meetings that produced a series of agreements, in particular the Humanitarian Law on Armed Conflict, a group of international laws for the humane treatment of wounded or captured military personnel, medical personnel and non-military civilians during wars or armed conflicts. The agreements date back to 1864 and were extensively updated in 1949, after the Second World War.
Under international law, the term convention does not have its common meaning as an assembly of people. On the contrary, it is used in diplomacy as an agreement or an international treaty. The 1864 Convention was ratified in three years by all major European powers as well as by many other states. It was amended and extended in 1906 by the Second Geneva Convention, and its provisions were applied to the command of maritime warfare by the Hague Conventions of 1899 and 1907. The Third Geneva Convention, the Convention on the Treatment of Poe wars (1929), required prisoners of war to treat prisoners of war humanely, provide information about them and authorize official visits by representatives of neutral states to detention camps. In the preamble to the 1949 Geneva Conventions, States Parties reaffirmed their „serious desire for peace among peoples.“
