In the thirteenth century the egyptians were driven out of palestine and back to their original frontiers by the

Egyptians were Sea Peoples. The Egyptians initially begat the name "Peoples of the Sea" for the remote contingents that the Libyans acquired to help their assault on Egypt in c. 1220 BC amid the rule of Pharaoh Merneptah. 
The circumstance in regards to the distinguishing proof of the Sea Peoples is more confused than you may understand. The real issue is that we just have scrappy composed records of their assaults on the setup societies of Egypt and the Near East, and these give just an unclear thought of where they originated from.
