The Third Intermediate Period

Learning Objective

  • Describe the general landscape of the political chaos during Third Intermediate Period

Key Points

  • The period of the Twenty-first Dynasty was characterized by the country’s fracturing kingship, as power became split more and more between the pharaoh and the High Priests of Amun at Thebes.
  • Egypt was temporarily reunified during the Twenty-second Dynasty, and experienced a period of stability, but shattered into two states after the reign of Osorkon II.
  • Civil war raged in Thebes and was eventually quelled by Osorkon B, who founded the Upper Egyptian Libyan Dynasty. This dynasty collapsed, however, with the rise of local city-states.
  • The Twenty-fourth Dynasty saw the conquest of the Nubians over native Egyptian rulers, and the Nubians ruled through the Twenty-Fifth Dynasty, when they expanded Egyptian power to the extent of the New Kingdom and restored many temples. Due to lacking military power, however, the Egyptians were conquered by the Assyrians toward the end of the Twenty-fifth Dynasty.
  • The end of the Third Intermediate Period and the Twenty-sixth Dynasty saw Assyrian rule over Egypt. Although some measure of independence was regained, Egypt faced pressure and eventual defeat at the hands of the Persians.

High Priests of Amun

The highest-ranking priest in the priesthood of the Ancient Egyptian god, Amun. Assumed significant power along with the pharaoh in the Twenty-First Dynasty.

The Third Intermediate Period of Ancient Egypt began with the death of the last pharaoh of the New Kingdom, Ramesses XI in 1070 BCE, and ended with the start of the Postdynastic Period. The Third Intermediate Period was one of decline and political instability. It was marked by a division of the state for much of the period, as well as conquest and rule by foreigners. However, many aspects of life for ordinary Egyptians changed relatively little.

The Twenty-First Dynasty (c. 1077-943 BCE)

The period of the Twenty-first Dynasty was characterized by the country’s fracturing kingship. Even in Ramesses XI’s day, the Twentieth Dynasty of Egypt was losing its grip on power in the city of Thebes, where priests were becoming increasingly powerful. The Amun priests of Thebes owned 2/3 of all the temple lands in Egypt, 90% of ships, and many other resources. Consequently, the Amun priests were as powerful as the Pharaoh, if not more so. After the death of Ramesses XI, his successor, Smendes I, ruled from the city of Tanis, but was mainly active only in Lower Egypt. Meanwhile, the High Priests of Amun at Thebes effectively ruled Middle and Upper Egypt in all but name. During this time, however, this division was relatively insignificant, due to the fact that both priests and pharaohs came from the same family.

The Twenty-Second (c. 943-716 BCE) and Twenty-Third (c. 880-720 BCE) Dynasties

The country was firmly reunited by the Twenty-second Dynasty, founded by Shoshenq I in approximately 943 BCE. Shoshenq I descended from Meshwesh immigrants originally from Ancient Libya. This unification brought stability to the country for well over a century, but after the reign of Osorkon II, the country had shattered in two states. Shoshenq III of the Twenty-Second Dynasty controlled Lower Egypt by 818 BCE, while Takelot II and his son Osorkon (the future Osorkon III) ruled Middle and Upper Egypt. In Thebes, a civil war engulfed the city between the forces of Pedubast I, a self-proclaimed pharaoh. Eventually Osorkon B defeated his enemies, and proceeded to found the Upper Egyptian Libyan Dynasty of Osorkon III, Takelot III, and Rudamun. ┬áThis kingdom quickly fragmented after Rudamun’s death with the rise of local city-states.

The Twenty-Fourth Dynasty (c. 732-720 BCE)

The Nubian kingdom to the south took full advantage of the division of the country. Nubia had already extended its influence into the Egyptian city of Thebes around 752 BCE, when the Nubian ruler Kashta coerced Shepenupet into adopting his own daughter Amenirdis as her successor. Twenty years later, around 732 BCE, these machinations bore fruit for Nubia when Kashta’s successor Piye marched north in his Year 20 campaign into Egypt, and defeated the combined might of the native Egyptian rulers.

The Twenty-Fifth Dynasty (c. 760-656 BCE)

Following his military conquests, Piye established the Twenty-fifth Dynasty and appointed the defeated rulers as his provincial governors. Rulers under this dynasty originated in the Nubian Kingdom of Kush. Their reunification of Lower Egypt, Upper Egypt, and Kish created the largest Egyptian empire since the New Kingdom. They assimilated into Egyptian culture but also brought some aspects of Kushite culture. During this dynasty, the first widespread building of pyramids since the Middle Kingdom resumed. The Nubians were driven out of Egypt in 670 BCE by the Assyrians, who installed an initial puppet dynasty loyal to the Assyrians.

End of the Third Intermediate Period

Upper Egypt remained under the rule of Tantamani for a time, while Lower Egypt was ruled by the Twenty-sixth Dynasty, starting in 664 BCE. Although originally established as clients of the Assyrians, the Twenty-sixth Dynasty managed to take advantage of the time of troubles facing the Assyrian empire to successfully bring about Egypt’s political independence. In 656 BCE, Psamtik I (last of the Twenty-sixth Dynasty kings) occupied Thebes and became pharaoh, the King of Upper and Lower Egypt. He proceeded to reign over a united Egypt for 54 years from his capital at Sais. Four successive Saite kings continued guiding Egypt through a period of peace and prosperity from 610-525 BCE. Unfortunately for this dynasty, however, a new power was growing in the Near East: Persia. Pharaoh Psamtik III succeeded his father, Ahmose II, only six months before he had to face the Persian Empire at Pelusium. The new king was no match for the Persians, who had already taken Babylon. Psamtik III was defeated and briefly escaped to Memphis. He was ultimately imprisoned, and later executed at Susa, the capital of the Persian king Cambyses. With the Saite kings exterminated, Camybes assumed the formal title of Pharaoh.
