Egyptian–Hittite peace treaty
The Egyptian–Hittite peace treaty, also known as the Eternal Treaty or the Silver Treaty, was concluded between Ramesses II of the Egyptian Empire and Ḫattušili III of the Hittite Empire around 1259 BC. It is the oldest known surviving peace treaty (though the much older treaty between Ebla and Abarsal may be the earliest recorded diplomatic treaty in human history) and the only one from the ancient Near East for which versions from each party have survived. Though it is sometimes called the Treaty of Kadesh, the text itself does not mention the Battle of Kadesh, which took place around 1274 BC. Both sides of the treaty have been the subject of intensive scholarly study.
