The Convention on the wounded and sick of 1929 represents the third version of the Geneva Convention after those of 1864 and 1906. It was based on the experience of World War I. The alterations which were adopted were of lesser importance than those of 1906. The division into chapters and articles remained essentially unchanged. New provisions were inserted concerning the protection of medical aircraft and the use of the distinctive emblem in time of peace. Furthermore, the emblems of the red crescent and of the red lion and sun were recognized for countries which already used those signs in place of the red cross. The provisions concerning repatriation of the seriously wounded and seriously sick prisoners were transferred to the Convention on prisoners of war. The Convention of 1929 was replaced by the Geneva Convention (I) of 1949.
The 1929 Convention for the Amelioration of the Condition of the Wounded and Sick in Armies in the Field was replaced by the first Geneva Convention of 12 August 1949 (Geneva Convention I). It is no longer in operation following the universal acceptance of the Geneva Conventions of 1949.
