The creation of the Chemical Weapons Convention (CWC) was driven by the international community's long-standing effort to address the horrors of chemical warfare, which first gained global attention during World War I.
Key events and factors leading to the CWC include:
- Early Limitations: Initial attempts to curb chemical weapons, such as the 1899 and 1907 Hague conferences, failed to prevent their widespread use in World War I, which resulted in over one million casualties.1
- The 1925 Geneva Protocol: This treaty banned the use of poison gas in war but failed to prohibit the development, production, or stockpiling of such weapons. Many nations also reserved the right to retaliate in kind, leading to the massive buildup of chemical arsenals during the Cold War.12
- Post-WWII Disarmament: Following the success of the 1972 Biological Weapons Convention, UN negotiators shifted their focus to chemical disarmament.1
- Diplomatic Shifts: Progress was long blocked by Cold War tensions. However, improved relations between the U.S. and the Soviet Union under Mikhail Gorbachev in the mid-1980s, followed by the dissolution of the Soviet Union, allowed for a consensus on a comprehensive, verifiable ban.13
The CWC was finally adopted in 1992 and entered into force in 1997, establishing a robust regime to eliminate chemical weapons stockpiles and production facilities globally.13
