Abimilku (also spelled Abi-Milku or Abimilki) around 1347 BC held the rank of Prince of Tyre (called "Surru" in the letters), during the period of the Amarna letters correspondence (1350-1335 BC). He is the author of ten letters to the Egyptian pharaoh, EA 146-155 (EA for 'el Amarna'). In letter EA 147, Pharaoh Akhenaten confirmed him as ruler of Tyre upon the death of his father, and in EA 149, referred to him with the rank of rabisu (general).
Abimilku is not referenced by name in any other letters of the 382-letter corpus. His name has been linked with the biblical Abimelech. His name means "My father (is) king."
Following the request of Akhenaten to disseminate his political updates in Kinaha, some other city states rebelled against this decision. The background was the vacancy in the position of rabisu in the garrison of Tyre, which Akhenaten staffed with non-Egyptians for organizational reasons. Eventually, as in letter EA 149, Akhenaten conferred the status of rabisu of Tyre upon Abimilku.
Zimredda of Sidon, and Aziru of Amurru, previously allied with Abimilku, responded by conquering Sumuru and occupying the territories around Tyre. Abimilku advised Amenhotep of the dangerous situation in several letters. In letter EA 151, Abimilku mentions the Danunans: "Behold, dangerous enemies are besieging Tyre. The king of Danuna is meanwhile dead; his brother now reigns. He behaves peacefully toward me."
Later in the letter, Abimilki warns of the rebels: "Behold, the fort of Tyre is running out of fresh water and wood. I will send you Ilu-milku as a messenger. At present there are no Hittite troops, but Aitakama of Kadesh is together with Aziru in battle against Biryawaza of Damascus. Meanwhile, Zimredda has been reinforced with troops and ships from Aziru; he has besieged me, and it is very dangerous.
The titles of Abimilku's letters are as follows:
The topic of "A Hymn to the Pharaoh" is not Zimredda; however, the war of Aziru son or Abdi-Ashirta, the constant lookout, and reporting by Zimredda is addressed at the very end of this letter.
