On 27 July 1929, in Geneva, the Convention for the Amelioration of the Condition of the Wounded and Sick in Armies in the Field is signed — the 1929 revision of the First Geneva Convention.

The Convention updates protection for medical personnel, sanitary units and the Red Cross emblem, drawing on First World War experience.

Adopted alongside the 1929 Prisoners of War Convention, it forms the core of interwar humanitarian law before the 1949 Conventions.

Entry into force: 19 June 1931. It was later replaced by the First Geneva Convention of 1949.

For humanitarian law, 27 July 1929 marks the modernisation of protection for the wounded on the battlefield.
