The Convention relative to the Treatment of Prisoners of War was adopted in Geneva on July 27th 1929. It was later revised alongside the pre-dating Convention protecting the war wounded and remains in force today as the third of the four 1949 Geneva Conventions. In 1929, the adoption of this first multilateral treaty entirely dedicated to the protection of prisoners of war (POW) filled an important gap in the international legal framework and crystallized a major shift in the way prisoners of war were perceived, fully recognizing them as ‘humanitarian subjects.’
