The 27th dynasty

According to the Greek historian Herodotus, who visited Egypt in about 450 bce, Cambyses II’s conquest of Egypt was ruthless and sacrilegious. Contemporary Egyptian sources, however, treat him in a more favorable light. He assumed the full titulary of an Egyptian king and paid honor to the goddess Neith of Sais. His unfavorable later reputation probably resulted from adverse propaganda by Egyptian priests, who resented his reduction of temple income. Darius I, who succeeded Cambyses in 522 bce and ruled as pharaoh until 486 bce, was held in higher esteem because he was concerned with improving the temples and restored part of their income, and because he codified laws as they had been in the time of Amasis. These stances, which aimed to win over priests and learned Egyptians, were elements of his strategy to retain Egypt as a lasting part of the Persian Empire. Egypt, together with the Libyan oases and Cyrenaica, formed the sixth Persian satrapy (province), whose satrap resided at Memphis, while Persian governors under him held posts in cities throughout the land. Under Darius I the tax burden upon Egyptians was relatively light, and Persians aided Egypt’s economy through irrigation projects and improved commerce, enhanced by the completion of the canal to the Red Sea.

The Persian defeat by the Athenians at Marathon in 490 bce had significant repercussions in Egypt. On Darius I’s death in 486 bce, a revolt broke out in the delta, perhaps instigated by Libyans of its western region. The result was that the Persian king Xerxes reduced Egypt to the status of a conquered province. Egyptians dubbed him the “criminal Xerxes.” He never visited Egypt and appears not to have utilized Egyptians in high positions in the administration. Xerxes’ murder in 465 bce was the signal for another revolt in the western delta. It was led by a dynast, Inaros, who acquired control over the delta and was supported by Athenian forces against the Persians. Inaros was crucified by the Persians in 454 bce, when they regained control of most of the delta. In the later 5th century bce, under the rule of Artaxerxes I (ruled 465–424 bce) and Darius II Ochus (ruled 423–404 bce), conditions in Egypt were very unsettled, and scarcely any monuments of the period have been identified.

The 28th, 29th, and 30th dynasties

The death of Darius II in 404 bce prompted a successful rebellion in the Nile delta, and the Egyptian Amyrtaeus formed a Saite 28th dynasty, of which he was the sole king (404–399 bce). His rule was recognized in Upper Egypt by 401 bce, at a time when Persia’s troubles elsewhere forestalled an attempt to regain Egypt.

Despite growing prosperity and success in retaining independence, 4th-century Egypt was characterized by continual internal struggle for the throne. After a long period of fighting in the delta, a 29th dynasty (399–380 bce) emerged at Mendes. Achoris (ruled 393–380 bce), its third ruler, was especially vigorous, and the prosperity of his reign is indicated by many monuments in Upper and Lower Egypt. Once again Egypt was active in international politics, forming alliances with the opponents of Persia and building up its army and navy. The Egyptian army included Greeks both as mercenaries and as commanders; the mercenaries were not permanent residents of military camps in Egypt but native Greeks seeking payment for their services in gold. Payment was normally made in non-Egyptian coins, because as yet Egypt had no coinage in general circulation; the foreign coins may have been acquired in exchange for exports of grain, papyrus, and linen. Some Egyptian coins were minted in the 4th century, but they do not seem to have gained widespread acceptance.

Aided by the Greek commander Chabrias of Athens and his elite troops, Achoris prevented a Persian invasion; but after Achoris’s death in 380 bce his son Nepherites II lasted only four months before a general, Nectanebo I (Nekhtnebef; ruled 380–362 bce) of Sebennytos, usurped the throne, founding the 30th dynasty (380–343 bce). In 373 bce the Persians attacked Egypt, and, although Egyptian losses were heavy, disagreement between the Persian satrap Pharnabazus and his Greek commander over strategy, combined with a timely inundation of the delta, saved the day for Egypt. With the latent dissolution of the Persian Empire under the weak Artaxerxes II, Egypt was relatively safe from further invasion; it remained prosperous throughout the dynasty.

Egypt had a more aggressive foreign policy under Nectanebo’s son Tachos (ruled 365–360 bce). Possessing a strong army and navy composed of Egyptian Machimoi and Greek mercenaries and supported by Chabrias and the Spartan king Agesilaus, Tachos (in Egyptian called Djeho) invaded Palestine. But friction between Tachos and Agesilaus and the cost of financing the venture proved to be Tachos’s undoing. In an attempt to raise funds quickly, he had imposed taxes and seized temple property. Egyptians, especially the priests, resented this burden and supported Tachos’s nephew Nectanebo II (Nekhtharehbe; ruled 360–343 bce) in his usurpation of the throne. The cost of retaining the allegiance of mercenaries proved too high for a nonmonetary economy.

Agesilaus supported Nectanebo in his defensive foreign policy, and the priests sanctioned the new king’s building activities. Meanwhile, Persia enjoyed a resurgence under Artaxerxes III (Ochus), but a Persian attack on Egypt in 350 bce was repulsed. In 343 bce the Persians once again marched against Egypt. The first battle was fought at Pelusium and proved the superiority of Persia’s strategy. Eventually the whole delta, and then the rest of Egypt, fell to Artaxerxes III, and Nectanebo fled to Nubia.

The 4th century bce was the last flourishing period of an independent Egypt and was a time of notable artistic and literary achievements. The 26th dynasty artistic revival evolved further toward more-complex forms that culminated briefly in a Greco-Egyptian stylistic fusion, as seen in the tomb of Petosiris at Tūnah al-Jabal from the turn of the 3rd century bce. In literature works continued to be transmitted, and possibly composed, in hieratic, but that tradition was to develop no further. Demotic literary works began to appear, including stories set in the distant past, mythological tales, and an acrostic text apparently designed to teach an order of sounds in the Egyptian language.

The second Persian period

Artaxerxes III dealt harshly with Egypt, razing city walls, rifling temple treasuries, and removing sacred books. Persia acquired rich booty in its determination to prevent Egypt from further rebelling. After the murder of Artaxerxes III, in 338 bce, there was a brief obscure period during which a Nubian prince, Khabbash, seems to have gained control over Egypt, but Persian domination was reestablished in 335 bce under Darius III Codommanus. It was to last only three years.
