18th dynasty- Egypt’s stability was briefly ruptured when the late 18th Dynasty king Amenhotep IV, also known as Akhenaten, changed the Egyptian religion and had most temples closed, favoring one new god, the solar-deity Aton. During this period of turmoil and upheaval, the so-called Amarna-revolution, Egypt lost a lot of its former influence in Asia and Nubia
19th dynasty (1307-1196) – The 19th Dynasty ended in dynastic upheaval. Although Seti was the legitimate successor of his father, Merenptah, another descendant of Ramesses II, Amenmes, appears to have successfully claimed the throne for himself, at least for a few Egyptian Years in the south of the country.
It is not known whether this happened at the beginning or somewhere during the reign of Seti II, but was is certain is that Seti outlived his rival and carefully set about to erase his titulary and usurp his monuments.
