The boy-king of Egypt, began his rule as Egypt was still under the religious changes of Akenhaten, Tutankhamun was married to Ankhesenpaaten (possibly his half-sister, since Ankhesenpaaten is unequivocally recorded as another of the six daughters of Akhenaten and Nefertiti), and after the re-establishment of the traditional Egyptian religion the couple changed the –aten ending of their names to the –amun ending, becoming Ankhesenamun and Tutankhamun. They are known to have had two children, both girls, whose mummies were discovered in Tutankhamun's tomb - they both died as babies, and medical evidence suggests they may have been stillborn.
