Smenkhkare was an ancient Egyptian pharaoh of unknown background who lived and ruled during the Amarna Period of the 18th Dynasty. Smenkhkare was husband to Meritaten, the daughter of his likely co-regent, Akhenaten. Since the Amarna period was subject to a large-scale condemnation of memory by later pharaohs, very little can be said of Smenkhkare with certainty, and he has hence been subject to immense speculation.

KV55 is a tomb in the Valley of the Kings in Egypt. It was discovered by Edward R. Ayrton in 1907 while he was working in the Valley for Theodore M. Davis. It has long been speculated, as well as much disputed, that the body found in this tomb was that of the famous king, Akhenaten, who moved the capital to Akhetaten. The results of genetic and other scientific tests published in February 2010 have confirmed that the person buried there was both the son of Amenhotep III and the father of Tutankhamun. Furthermore, the study established that the age of this person at the time of his death was consistent with that of Akhenaten, thereby making it almost certain that it is Akhenaten's body. However, a growing body of work soon began to appear to dispute the assessment of the age of the mummy and the identification of KV55 as Akhenaten.
