The Path to the CWC

On this page, you will find a growing archive of the various documents involved in the 20+ years of negotiating that led to the Chemical Weapons Convention. According to the OPCW, serious discussions on biological and chemical weapons treaties started in 1968 at the Disarmament Conference in Geneva, so our archive begins in 1968.

With this archive, you can trace the path of history as negotiators grappled with fundamental questions: how do you define a chemical weapon? How should stockpiles be destroyed? How do you make an implementing body? What should be done about abandoned chemical weapons? Many of the documents included in this archive come from the Documents on Disarmament series published by the United States Arms Control and Disarmament Agency. If you have a document you think we should include, email us via the Contact Us page.
