List of weapons of mass destruction treaties

A variety of treaties and agreements have been enacted to regulate the use, development and possession of various types of weapons of mass destruction. Treaties may regulate weapons use under the customs of war, ban specific types of weapons, limit weapons research, limit allowable weapons stockpiles and delivery systems or regulate civilian use of weapon precursors. The history of weapons control has also included treaties to limit effective defense against weapons of mass destruction in order to preserve the deterrent doctrine of mutual assured destruction as well as treaties to limit the spread of nuclear technologies geographically.
There is a separate list of states parties to several of the major weapons of mass destruction treaties.
