The Battle of Kadesh and the Earliest Peace Treaty
Around 1274 BC Ramesses II led his army against the Hittite Empire at Kadesh in Syria; both sides claimed victory (the Egyptian account plainly bears elements of propagandistic exaggeration), the battle itself was undecided, and the two later signed a peace treaty around 1258 BC, a copy of the Hittite cuneiform tablet of the treaty text still displayed at the United Nations headquarters, symbolizing this earliest surviving document of an international peace treaty.
The Abu Simbel Temples
Ramesses II ordered the Abu Simbel temples cut into the rock in the region of Nubia, their facades carved with four colossal pharaoh statues about 20 meters high, their orientation carefully designed so that on two specific days each year the sun shines precisely into the innermost sanctuary — when the Aswan High Dam was built in the twentieth century, the temple was cut apart and relocated as a whole to higher ground to avoid being flooded, a famous engineering feat in the history of modern heritage preservation.
