Week 02: Introduction: Formation and Conclusion of Treaties

 

Treaties can be traced back as far as the early-recorded history of Mankind.  Evidence for their existence has been found throughout the history. Treaties have been the major legal instruments for regulating relations between States.  States concluded treaties in every conceivable subject.  Ten of thousands treaties have been registered with the United Nations since 1946.  Until 1980, treaties had been governed by international customary law.  In 1969, the Vienna Convention on the Law of Treaties was signed, codifying and developing existing customary rules; it came into force in 1980.
