The Geneva Protocol of 1925 (The Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or Other Gases, and of Bacteriological Methods of Warfare) was a law that made it illegal to fight with chemical or biological weapons in war. The Geneva protocol was signed on June 17, 1925 and the protocol was entered into force on January 8, 1928. Before, it was signed by some countries like the United Kingdom and France originally. Any country who has signed this Protocol must follow it.
