Peace treaty
The treaty was made in year 21 of Ramesses' reign, probably 1258 BC.p257 It contains a mutual-assistance pact in case one of the empires should be attacked by a third party, or in the event of internal strife. There are articles on the forced repatriation (sending back) of refugees, and provisions that they should not be harmed. So this might be called the first extradition treaty. There are also threats of retribution, should the treaty be broken.
