This man wrote a hymn whi
This man wrote a hymn which has been compared to Psalm 104, and though some have questioned whether he was impotent, he apparently fathered six daughters, one of whom married his successor, Smenkhare.  His father broke with traditional incest rules by marrying a commoner named Tiy.  Egypt may have lost all of its Asian holdings except part of Palestine under this man's rule, as indicated by the Amarna letters, discovered at the site where he attempted to build a new capital.  For 10 points, name this husband of Nefertiti, who attempted to institute monotheism in Egypt with worship of Aton.
