During the
Old and
Middle Kingdom of Egypt, Libya to the west was not a major security concern for the Egyptian pharaohs aside from occasional raiding warfare. The situation appears to have changed under the late
Eighteenth Dynasty of Egypt, as the Egyptian military invested more resources in securing the western borders of Egypt. From the early
Nineteenth Dynasty of Egypt, fortresses were built west of modern-day
Alexandria to shield the
Nile Delta from Libyan (
Libu) incursions. However, at least one of these new bastions,
Zawyet Umm El Rakham, was quickly abandoned.
Egyptologist Ian Shaw argued that Zawyet Umm El Rakham's short existence suggests that the Libyan tribes increasingly pushed eastward, forcing the Egyptians to evacuate the fortress; this push ultimately culminated in the Libyan invasion during
Merneptah's reign. (left) and
Ra-Horakhty In the late
13th century BC, a famine in Libya compelled many of the tribes in the region to unite under the leadership of a chief known as
Meryey. The Libyan alliance included the
Tjehenu and
Meshwesh. Together these tribes prepared to invade Egypt. Their exact intentions are unclear but they most likely wished to conquer territory within the borders of Egypt, including
Memphis. Meryey's coalition probably numbered tens of thousands; this force possibly included not just warriors but also their families and possessions such as cattle and portable wealth. However, the Egyptian plunder lists compiled after the Battle of Perire mention only the family of King Meryey, and no other women or children. This omission is notable, given that the Egyptian records describe the spoils in extensive detail, including even minor items such as arrowheads. Thus, historian Konstantinos Kopanias argued that the invading force consisted mainly of soldiers, rather than large groups of dependants. Furthermore, the Libyans allied with or hired a substantial contingent of Sea Peoples, including
Shekelesh, Teresh,
Ekwesh,
Lukka, and
Sherden; members of the last group also served in the
Egyptian military. The Libyans possibly used their wealth, gained through control of trade from
Central Africa to the
Mediterranean Sea, to hire the Sea Peoples as mercenaries. The Libyans first captured an oasis to the west of Egypt; modern researchers have speculated that this oasis may have been the
Bahariya or
Siwa Oasis. From there, the Libyan force advanced to
Farafra. This was a strategically central location in the region, as holding Farafra allowed the Libyans to control the routes between the local oases, send messages to
Nubia, and to strike at several parts of Egypt. According to Egyptologist
Colleen Darnell, this showcases that Meryey was pursuing a
grand strategy: As Farafra allowed them access to at least three invasion routes, the Libyans could surprise the Egyptians despite the latter's knowledge of their military preparations. In addition, Meryey possibly contacted Libo-Nubians south of Farafra and enlisted them in his plan. The latter is indicated by the
Amada Stele, which records Nubian raids in
Upper Egypt two days before the Battle of Perire. Darnell speculated that the contemporariness of the raids and battle hint at a wider alliance in which Meryey's Libyans and the Libo-Nubians cooperated to divide Egypt between them, with Meryey claiming the
Nile Delta and the Libo-Nubians conquering the rich, Egyptian-held regions of Nubia. After making their preparations, Meryey's Libyans moved from Farafra to Perire, most likely a city in the Nile Delta region. As a result of the scarcity of resources in the desert, the Libyans possibly split into a number of columns instead of operating as a single army. The
Great Karnak Inscription poetically suggests that Meryey's main contingent advanced from Farafra to Bahariya, then into the
Faiyum, before entering the delta around Memphis. Another Libyan column possibly crossed the Nile in
Middle Egypt and then marched into the eastern delta, as the Karnak Inscription states that the Libyan vanguard camped at
Perbarset in the east. Such an operation would have disrupted the Egyptian communications and supply routes, cutting off Memphis,
Thebes, and
Pi-Ramesses from each other. Finally, the inscription hints at another column marching along the Mediterranean coast, as several Egyptian fortresses are mentioned as being destroyed. Such bastions were mainly concentrated along the coast. The Libyan column were accompanied by their families and possessions, further strengthening the assumption that they intended to settle in conquered territories instead of just plundering them. Meryey's army occupied parts of the western Nile Delta for about a month before the battle at Perire erupted. == Battle ==
