While the Fifth and Sixth dynasties were reigning, exploring expeditions were sent into the lands of the Upper Nile. The two dynasties had sprung from the island of Elephantinê, opposite Assuan; it was, therefore, perhaps natural that they should take an interest in the country to the south. One expedition made its way into the land of Punt, to the north of Abyssinia, and brought back a Danga dwarf, whose tribal name still survives under the form of Dongo. Later expeditions explored the banks of the Nile as far south as the country of the Dwarfs, as well as the oases of Libya.
The Old Empire was followed by a period of decline. Egypt was overrun by barbarians, its kings lost their power, and the whole land suffered decay. The pyramid tombs of the Old Empire were entered and despoiled; the bodies of the monarchs within them were torn to pieces, and the precious objects that had been buried with them were carried away. As the power of the kings diminished, that of the great landowners and nobles increased; a feudal aristocracy grew up, which divided Egypt between its members, and treated the royal authority with only nominal respect. Memphis ceased to be the capital, and a new dynasty, the Ninth, was founded by the feudal prince of Herakleopolis, now Ahnas, south of the Fayyûm. For a time the Tenth dynasty succeeded in reducing its rebellious vassals to obedience, but the princes of Thebes steadily grew in strength, and at length one of them seized the throne of the Pharaohs and established the Eleventh dynasty. Thebes became the capital of the kingdom, and under the Twelfth dynasty was the capital of an empire.
Once more Egypt revived. The power of the aristocracy was broken, and the local princes became court officials. Temples were built, and engineering works undertaken all over the country. The ancient temple of Ra at Heliopolis was restored, and two obelisks, one of which is still standing, were planted in front of it. The depression west of the Nile, now known as the Fayyûm, was drained of its waters, and by means of embankments transformed from a pestiferous marsh into fertile fields. The Nile was brought to it by a river-like canal, and the supply of water regulated by locks. Fresh exploring expeditions were sent to the Somali coast and elsewhere. The gold-mines of Hammamât were worked in the eastern desert, and Egypt became the California or Australia of the ancient world. The eastern frontier was defended against the Asiatic tribes, while campaign after campaign was carried on in the south, resulting in the conquest of the Sudan.
The Thirteenth dynasty came to an end in the midst of internal troubles. The short reigns of the kings of the dynasty that followed show that the line of the Pharaohs was again becoming feeble. It closed in disaster and overthrow. Hordes of invaders poured into Egypt from Asia and overran the whole country. They are known as the Hyksos or Shepherds, and the greater part of them were of Semitic descent. For 669 years they ruled the valley of the Nile in three dynasties, and the recollection of their hated sway never faded from the Egyptian mind. At first they burned and plundered, then they established themselves in Memphis and Zoan, and from thence governed the rest of the country. But they soon submitted to the influence of Egyptian culture. The conquered people took their conquerors captive, and the Hyksos kings became veritable Pharaohs. The manners and customs, the writing and titles of the native monarchs were adopted, and, in course of time, even the language also. The court was filled with native officials, the cities and temples were restored, and Egyptian learning was patronised. One of the few Egyptian treatises on mathematics that have come down to us is dedicated to a Hyksos sovereign. It was only in religion that the new rulers of Egypt remained foreign.
They continued to worship a form of the Semitic Baal, who was invoked under the Hittite name of Sutekh. An attempt to impose his worship upon the native Egyptians led to the war of independence which ended in the expulsion of the stranger. Apophis III., of the Seventeenth dynasty, sent messengers to Skenen-Ra, the prince of Thebes, bidding him renounce Amon of Thebes for the god of his suzerain. Skenen-Ra resisted, and a long war followed, which, after lasting through five generations, resulted in the complete triumph of the Egyptians. The Hyksos were driven back into Asia, and the prince of Thebes was acknowledged the Pharaoh of an united Egypt (B.C. 1600).
It was while the Hyksos kings were reigning that Abraham visited the Delta. Their court was held at Zoan, now Sân, close to the Asiatic frontier, and on the frontier itself stood their fortress of Avaris, which served at once to bar the way from Asia and to overawe the conquered Egyptians. The Pharaoh of Joseph was probably Apophis III. If so, the Hebrew vizier would have witnessed the outbreak of the war of independence towards the close of the long reign of the Hyksos king. It may be that the policy which transferred the soil of Egypt from the people to the king and the priests gave its first impulse to the movement.
The Eighteenth dynasty founded an Egyptian empire. Its kings carried the war into Asia, and planted the boundaries of Egyptian dominion on the banks of the Euphrates. Thothmes III. (B.C. 1503-1449) made Canaan an Egyptian province, dividing it into districts, each under a governor or a vassal prince, who was visited from time to time by a royal commissioner. Carriage roads were constructed, with posting inns at intervals along them where food and lodging could be procured. The country east of the Jordan equally obeyed Egyptian rule. The plateau of Bashan was governed by a single prefect; Ammon and Moab were tributary; Edom alone retained its independence, thanks to its barren mountains, and inaccessible ravines. Thebes, the capital of the dynasty, was adorned with splendid buildings, and all the wealth and luxury of Asia was poured into it. Thothmes established zoological and botanical gardens, where the strange plants, birds, and animals he had collected in his campaigns could be preserved. His immediate predecessor, Queen Hatshepsu, had already revived the exploring expeditions of earlier centuries. An exploring fleet had been sent by her to Punt, the land of frankincense, and it returned home with rarities of all kinds, including apes and giraffes. The history of the expedition and the treasures it brought back were depicted on the walls of the temple built by the queen at Dêr el-Bâhari, after the design of the architect Sen-Mut.
The authority of Egypt was not extended to the Euphrates only. Cyprus sent tribute to the Pharaoh, the coasts of Asia Minor, perhaps also of Greece, were harried, and the Sudan was conquered as far south as Berber, if not Khartûm. Under Amen-hotep III., the grandson of Thothmes III., the empire underwent still farther extension. Egyptian temples were erected on the banks of the Upper Nile, and Napata, the future capital of Ethiopia, was built at Gebel Barkal, beyond Dongola.
In Asia, Mitanni was the first neighbour of Egypt that had maintained its independence. Assyria and the Mesopotamian prince of Singar or Shinar had paid tribute to Thothmes III.; so, too, had the Hittite king, and even Babylonia had been forced to acquiesce sullenly in the annexation by Egypt of her old province of Canaan, and to beg for gifts of gold from the Egyptian mines. But Mitanni was too powerful to be attacked. Her royal family accordingly married into the Solar race of Egypt. One of her princesses was the mother of Amen-hotep III.; another was probably the mother of his son and successor, Amen-hotep IV.
