Final answer:
New Kingdom pharaohs like Akhenaten were removed from historical records due to religious conflicts and attempts to restore Egypt's traditional religious order. His successors sought to erase his influence from history. The decline of the New Kingdom also involved political fragmentation, leading to further alterations of historical records.
Step-by-step explanation:
Some New Kingdom pharaohs were removed from the historical record by their successors due to religious conflicts. This largely occurred after the reign of Akhenaten, who attempted a revolutionary religious transformation by imposing the worship of Aten and undermining Egypt’s traditional polytheistic beliefs. Following his death, powers with vested interests in the traditional order, including new pharaohs such as Tutankhamun, began restoring old religious practices and actively sought to erase Akhenaten's legacy from history as part of a broader push to re-establish the religious and social order he had disrupted.
The New Kingdom also faced political fragmentation during its decline, with the rise of powerful nobles and a series of foreign invasions. This period of instability saw the altering or erasure of historical records by different groups trying to cement their own legitimacy and authority by distancing themselves from perceived failures of past rulers.
