Herodotus recounts of one possible motive for Cambyses II desire to conquer Egypt: According to Herodotus, Amasis II came to power by bloody means by defeating, and murdering his predecessor pharaoh Apries. While in power, Amasis, was requested by either Cyrus the Great, or Cambyses II for the best Egyptian eye doctor. Amasis II complied, but did so at the expense of forcing the physician to leave his family and children behind and forcibly sent him to Persia. In an attempt to exact revenge for this unjust exile, the Egyptian ophthalmologist, persuaded king Cambyses II to strengthen his bonds with Egypt through marriage with the daughter of Amasis II. Cambyses II complied and asked Amasis II for his daughters's hand in marriage.
