The Mitannian Empire was at an end. Mattiwaza gained Hittite support and
took the throne of Mitanni with the aid of Suppiluliumas' army. He
remained a vassal of the Hittites, however, and his marriage to a
daughter of Suppiluliumas further strengthened Hittite power in Mitanni.
At the same time Ashuruballit of Assyria took advantage of the situation
to seize the portion of Mitanni nearest to him. Assyria had been
controlled alternately by Mitanni from the west and by Babylon from the
south, but Ashuruballit determined to head an independent state.
To strengthen his position, Ashuruballit sent messengers to Akhenaton
with a present of two white horses and a silver chariot. The letter
accompanying these gifts[30] asks nothing in return, but a second
letter[31] mentions a new palace that Ashuruballit is building, with the
suggestion, "If thou art very friendly disposed, then send much gold."
Evidently the Assyrian embassy was received with courtesy in the court
of Akhenaton, for Burnaburiash of Babylon was unhappy at the thought
that Egypt would deal with a people who had been subject to Babylon. In
anger he dispatched a letter:
To Niphururia (i.e., Akhenaton), king of Egypt, say. Thus says
Burnaburiash, king of Karduniash (i.e., Babylon), brother. I am well.
May it be well with you, your house, your wives, your sons, your land,
your chief men, your horses, your chariots. Since my fathers and your
fathers established friendly relations with one another they sent rich
presents to one another, and they refused not any good request one of
the other. Now my brother has sent (only) two minas of gold as a
present. But now, if gold is plentiful send me as much as your
fathers, but if it is scarce send half of what your fathers did. Why
did you send (only) two minas of gold. Now, since my work on the House
of God is great, and I have undertaken its accomplishment vigorously,
send much gold. And you, whatsover you desire from my land, write and
it shall be brought to you. In the time of Kurigalzu, my father, the
Canaanites as one man wrote to him saying, "We will go against the
border of the land (i.e., Egypt), and we will stage an invasion, and
we will make an alliance with you." But my father wrote to them
saying, "Cease speaking of an alliance with me. If you are hostile
against the king of Egypt, my brother, and ally yourself with another,
I will come and will plunder you for he is in alliance with me." My
father did not listen to them for the sake of your father. Now,
concerning the Assyrians, my subjects, have I not written to you? If
you love me you will not do business with them. Let them accomplish
nothing. As a present I have sent to you three minas of beautiful
lapis-lazuli, and five span of horses for five wooden chariots.[32]
