How Kush became independent from Egypt?

It was first established around 1070 BCE when it gained its independence from Egypt. It quickly became a major power in Northeast Africa. In 727 BCE, Kush took control of Egypt and ruled until the Assyrians arrived. The empire began to weaken after Rome conquered Egypt and eventually collapsed sometime in the 300s CE.
