Which convention was related to Prisoners of War, cruelty and collective penalties and formulated for…

The 1929 Geneva Convention specifically regulated prisoners of war, including humane treatment, medical attention and prohibitions on cruelty and collective penalties. The Kellogg–Briand Pact concerned renunciation of war, and the Declaration of Paris chiefly concerned maritime warfare. The Hague instruments contained earlier prisoner rules, but the detailed convention identified here is Geneva 1929.

Current law: The Third Geneva Convention of 1949 subsequently replaced and expanded the prisoner-of-war framework between its parties. This question identifies the historical 1929 instrument.
