Through correspondence Prior diplomatic correspondence is evident, from study of the
Amarna letters and includes evidence of dialogue between
Thutmose IV and Kurigalzu as attested to by
Amenhotep III in his letter, designated EA 1 (EA for
El Amarna), to
Kadašman-Enlil.
Burna-Buriaš II reminded
Akhenaten in his letter, EA 11, that Kurigalzu had been sent gold by one of his ancestors, and, in
EA 9, reminded
Tutankhamen that Kurigalzu had turned down a request from the
Canaanites to form an alliance against Egypt.
Through marriage He gave his daughter to Amenhotep III, who was a serial practitioner of diplomatic marriages with two
Mitannite princesses and one from
Arzawa in his harem, and who would even later go on to wed Kurigalzu's granddaughter, the daughter of Kadašman-Enlil. A Neo-Babylonian copy of a literary text which takes the form of a letter, now located in the
Vorderasiatisches Museum in Berlin, is addressed to the Kassite court by an Elamite King and details the genealogy of the Elamite royalty of this period. Apparently, he married his sister to the Elamite king Paḫir-iššan, the son of Ige-Halki, and a daughter to his successor, Ḫumban-numena. This may have been Mishim-ruh, who is cited in royal inscriptions. The princess went on to bear Untash-Napirisha, the next king who subsequently married Burna-Buriaš’ daughter. The author of the letter is thought to be Shutruk-Nahhunte, ca. 1190-1155 BC, who claims descent from Kurigalzu's eldest daughter and also wed the eldest daughter of
Meli-Šipak, the 33rd Kassite king. Unfortunately the letter inserts
Nabu-apla-iddina (888 – 855 BC) “an abomination, son of a
Hittite”, into the narrative in the place one might have supposed that
Marduk-apla-iddina I was to appear, the substitution of dAMAR.UTU by dAG being an unlikely slip of the stylus, making a chronological conundrum and this may be the purpose of the “letter”, to denigrate the later king through the tongue of the earlier one. ==Building works==
