 Cambyses II then assumed the formal title of pharaoh, but ruled Egypt from his home of Susa in Persia (modern Iran), leaving Egypt under the control of a satrapy.The entire Twenty-seventh Dynasty of Egypt, from 525–402 BCE, save for Petubastis III, was an entirely Persian ruled period, with the Achaemenid Emperors all being granted the title of pharaoh.A few temporarily successful revolts against the Persians marked the fifth century BCE, but Egypt was never able to permanently overthrow the Persians.
