Did Egypt in 1400s BC come so weak that kush won its independence?

In the 1400s BC, Egypt was experiencing a period of decline known as the Second Intermediate Period, which weakened its control over neighboring regions. The Kingdom of Kush, located to the south of Egypt, took advantage of this instability and asserted its independence during this time. This shift was marked by a growing sense of identity and strength in Kush, ultimately allowing it to flourish as a separate entity from Egypt.
