Third Intermediate Period of Ancient Egypt

Following the breakdown of the New Kingdom, Lower Egypt was claimed by a new dynasty in Tanis, while the High Priest of Thebes took power in Upper Egypt. The two governing houses were frequently related. Third Intermediate Period is the modern designation for the third interruption of stable dynastic administrations in Egypt, which lasted for about 550 years (c. 1069-525 BCE).

Late in the Twenty-second Dynasty, civil war broke out, resulting in self-styled monarchs from Herakleopolis, Tanis, Hermopolis, Thebes, Memphis, and Sais taking power. Egypt was unable to organise a coherent defence as a result of this fragmentation when the Nubians invaded from the south and established the Twenty-Fifth Dynasty.

After being weakened by the Assyrians in the preceding century, the Persian invasion in 525 BCE ended Egyptian rule the Late period.

The order of Egyptian pharaohs is not always fixed. New discoveries can sometimes lead to changes in the accepted sequence. This is true for all Egyptian dynasties.
