Smenkhkare

Smenkhkare (alternatively romanized Smenkhare, Smenkare, or Smenkhkara; meaning "Vigorous is the soul of Re") was an ancient Egyptian pharaoh of unknown background who lived and ruled during the Amarna Period of the 18th Dynasty. Smenkhkare was married to Meritaten, the daughter of Akhenaten, Smenkhkare's probable co-regent. Since the Amarna period was subject to a large-scale condemnation of memory by later pharaohs, very little can be said with certainty about Smenkhkare, who therefore remains subject to immense speculation.

Some researchers believed that Smenkhkare was the same person as female pharaoh Neferneferuaten, while others maintain they were two different individuals. This article follows the stance that Smenkhkare was a male ruler, separate from Neferneferuaten. Smenkhkare is generally considered to have been Akhenaten's co-regent but he may also reigned independently.
