Northern Syria was thus formally conceded to the powerful conquerors who had descended from the mountains of Kappadokia, while Palestine remained under Egyptian dominion. But it was not destined to do so long. Ramses was succeeded by Meneptah, the fourteenth of his many sons, who had reigned only four years when the very existence of his kingdom was threatened by a formidable invasion from the west and north. “The peoples of the north” swarmed out of their coasts and islands, and a great fleet descended upon Egypt, in conjunction with the Libyans and Maxyes of northern Africa. Aqaiush or Achæans, Shardana or Sardinians, Tursha or Tyrsenians appear among them, as well as Leku from Asia Minor, and Zakkur, who a little later are the colleagues and brethren of the Philistines. Part of the Delta was overrun and devastated before the Pharaoh could make head against his foes. But a decisive battle was at length fought at Pa-Alu-sheps, not far from Heliopolis, which ended in the complete overthrow of the invading hordes. Egypt was saved from the danger which had threatened it, but it seems never to have recovered from the shock. The power of the government was weakened in the valley of the Nile itself, and one by one the foreign conquests passed out of its grasp. The sceptre of Seti II., who followed Meneptah, seems to have dropped into the hands of a usurper, Amon-messu by name: the history of the period is, however, involved in obscurity, and all that is certain is that the empire of Ramses II. was lost, and that Egypt itself fell into a state of decadence. With Si-Ptah the nineteenth dynasty came to an inglorious end. Its fall was the signal for internal confusion and civil war. A Syrian foreigner, Arisu by name, possessed himself of the throne of the Pharaohs, and Egypt for a while was compelled to submit to Canaanitish rule. Its leading nobles were in banishment, its gods were deprived of their customary offerings, and famine was added to the horrors of war. A deliverer came in the person of Set-nekht, the founder of the twentieth dynasty. He drove the stranger out the country, and restored it again to peace and prosperity. Hardly had his task been completed when he died, and was succeeded by his son, Ramses III. Under him a transient gleam of victory and conquest visited once more the valley of the Nile.
