Mitanni
Artatama I and Shuttarna II

Later on, Egypt and Mitanni became allies, and King Shuttarna II himself was received at the Egyptian court. Amicable letters, sumptuous gifts, and letters asking for sumptuous gifts were exchanged. Three Amarna letters (EA 182 EA 183 and EA 185) were sent by Shutarna with two being sent from "Mušiḫuna". Mitanni was especially interested in Egyptian gold. This culminated in a number of royal marriages: the daughter of King Artatama I was married to Thutmose IV. Kilu-Hepa, or Gilukhipa, the daughter of Shuttarna II, was married to Pharaoh Amenhotep III, who ruled in the early 14th century BC. In a later royal marriage Tadu-Hepa, or Tadukhipa, the daughter of Tushratta, was sent to Egypt.

When Amenhotep III fell ill, the king of Mitanni sent him a statue of the goddess Shaushka (Ishtar) of Nineveh that was reputed to cure diseases. A more or less permanent border between Egypt and Mitanni seems to have existed near Qatna on the Orontes River; Ugarit was part of Egyptian territory.

The reason Mitanni sought peace with Egypt may have been trouble with the Hittites. A Hittite king called Tudḫaliya I conducted campaigns against Kizzuwatna, Arzawa, Ishuwa, Aleppo, and maybe against Mitanni itself. Kizzuwatna may have fallen to the Hittites at that time.
