After World War I, chemical warfare was banned by the Geneva Protocol in 1925.

It was signed in Geneva on June 17, 1925 and entered into force on February 8, 1928. It was registered in the Treaty Series of the United Nations League on September 7, 1929.

It prohibits the use of chemical weapons and biological weapons, but says nothing about the production, storage or transfer of them. Later, other treaties covered these aspects (the Convention on Biological Weapons in 1972 and the Chemical Weapons Convention in 1992).
