Nectanebo II
For several years, Nectanebo II was successful in keeping Egypt safe from the Achaemenid Empire. However, betrayed by his former servant, Mentor of Rhodes, Nectanebo II was ultimately defeated by the combined Persian and Greek forces in the Battle of Pelusium (343 BC). The Persians occupied Memphis and then seized the rest of Egypt, incorporating the country into the Achaemenid Empire under Artaxerxes III. Nectanebo fled south and preserved his power for some time; his subsequent fate is unknown.
