Ankhesenpaaten was the third of six known daughters of the Pharaoh Akhenaten by his wife Nefertiti. She is believed to have been married firstly to her own father, by whom she was the mother of the princess Ankhesenpaaten Tasherit when she was twelve. After her father's death and a short marriage to Smenkhkare, she became the wife of Tutankhaten. Following their marriage, the couple honored the gods of the restored religion by changing their names to Tutankhamun and Ankhesenamun. When Tutankhamun died, she was married to Ay and died during or shortly after his reign.
A document was found in the ancient Hittite capital of Hattusa which dates to the Amarna period. It was addressed to the Hittite king, Suppiluliumas I and reads, "My husband has died and I have no son. They say about you that you have many sons, You might give me one of your sons to become my husband. I would not wish to take one of my subjects as a husband".
This document is extraordinary, for never before had anything like this occurred. In fact, Egyptians traditionally considered foreigners to be inferior. Suppiluliumas was understandably wary and had an envoy investigate, but by so doing, he missed his chance to bring Egypt into his empire. He did eventually send one of his sons, Zennanza, but the prince was murdered en route.
Debate wages over which queen authored the amazing message. Possible candidates are Nefertiti and Ankhesenpaaten. Ankhesenpaaten seems perhaps more likely since there were no candidates to the throne on the death of her husband, Tutankhamun, whereas Akhenaten had at least two legitimate successors.

Akhenaten, King of Egypt, by Cyril Aldred, 1988, Thames & Hudson.
Tutankhamun was the name now adopted by the boy who had become king and with his young wife Ankhesenamun they were too young to deal with the complex affairs of state let alone the now tattered factions of empire.
Ankhesenamun survived but with no children to continue the lineage she desperately tried to find a suitable heir, appealing to a foreign prince that by marriage to her would legitimise his place on the throne.
Ankhesenamun herself finally fades into oblivion shortly after this with kingship being passed into the hands of Aye, her fathers 'master of chariotry' and a prominent figure from the abandoned city of Akhetaton.
