About two years before his death, Thutmose III appointed his 18-year-old son, Amenhotep II (ruled c. 1426–1400 BCE), as coregent. Just before his father’s death, Amenhotep II set out on a campaign to an area in Syria near Kadesh, whose city-states were now caught up in the power struggle between Egypt and Mitanni; Amenhotep II killed seven princes and shipped their bodies back to Egypt to be suspended from the ramparts of Thebes and Napata.
In his seventh and ninth years, Amenhotep II made further campaigns into Asia, where the Mitannian king pursued a more vigorous policy. The revolt of the important coastal city of Ugarit was a serious matter because Egyptian control over Syria required bases along the littoral for inland operations and the provisioning of the army. Ugarit was pacified, and the fealty of Syrian cities, including Kadesh, was reconfirmed.
Thutmose IV
Amenhotep II’s son Thutmose IV (ruled 1400–1390 BCE) sought to establish peaceful relations with the Mitannian king Artatama, who had been successful against the Hittites. Artatama gave his daughter in marriage, the prerequisite for which was probably the Egyptian cession of some Syrian city-states to the Mitannian sphere of influence.
