King's Son (ancient Egyptian: zꜣ nsw) or the extended version King's Son of His Body (i.e. Prince) was an ancient Egyptian honorific title held by the sons of the Pharaoh. The title is the male equivalent of King's Daughter (i.e. Princess).
Only in a single occasion is the title given to a foreign prince. His name remains unknown; in the Amarna letters he is called Zannanza which is a reference to the title "King's Son" itself (zꜣ nsw). It is the only instance in ancient Egyptian history that a foreign prince was sent into diplomatic marriage with the Egyptian queen.
