Who was the kushite king in Africa that conquered Egypt?

Pianki was a Nubian king who conquered Egypt and founded the 25th Dynasty of Egypt in 744 BC. He was the first of a line of Nubian kings who would rule Egypt for over a century. Pianki's conquest of Egypt was the result of a long struggle between the Nubians and the Assyrians, who had conquered Egypt in 671 BC. Pianki defeated the Assyrians and their Egyptian allies in a series of battles, and he eventually captured Memphis, the capital of Egypt.
