Treaties and other instruments

Replica of the oldest known peace treaty dating from 1269 B.C. between Hattusilis and Ramses IIUnder Article 38, paragraph 1(a), of the Statute of the International Court of Justice, “international conventions whether general or particular, establishing rules expressly recognized by the contesting states” are identified as one of the primary sources of international law.

Several thousand such conventions and treaties have been adopted by States, a significant proportion of which are presently in force. Many of these instruments are reproduced in a number of treaty collections, including the United Nations Treaty Series which contains the various treaties registered with the United Nations in conformity with Article 102 of the Charter of the United Nations.

The following are links to online collections of treaties and other relevant international law instruments maintained by the United Nations and other international organizations, States and private entities. Some collections are dedicated to particular subjects of international law. In addition, links are provided to information on the status of treaties, including those deposited with the Secretary-General of the United Nations.
