Akhet Egyptology

Nachtenabo II was the last native Pharaoh to rule Egypt. He came to power while Egypt's main enemy, the Persian empire was in internal turmoil and this protected him from their aggression.
Once the Persian ruler Artaxerxes III had established a firm grip over his internal affairs he turned his attention again towards Egypt. Greek mercenaries fought on both sides, but the Persian forces were victorious. Nachtenabo was forced to take refuge in Nubia as one Egyptian city after another fell to the Persians.
