Attempts to Ban
- As soon as countries were able to mass produce chemical weapons, society immediately tried to ban them.
- in 1874 there was an attempt to ban "the employment of poisoned weapons" at Brussels Convention on the rules of war.
- In 1899, there was an attempt to ban projectiles with "the sole object of which is the diffusion of asphyxiating or deleterious gasses."
- Both attempts failed.
