According to the most important document of Tutankhamun's reign, the Restoration Stele, his father's supposed reforms left the country in a bad state. Consequently the traditional gods, seeing their temples in ruins and their cults abolished, had abandoned Egypt to chaos. When Tutankhamun came to the throne, his administration restored the old religion and moved the capital from Akhetaten back to its traditional home at Memphis. Although the reign of Tutankhamun is often thought to have little historical importance, his monuments tell a different story. He began repairing the damage inflicted upon the temples of Amun during Akhenaten's iconoclastic reign. He constructed his tomb in the Valley of the Kings,It is believed that his early death necessitated a hasty burial in a smaller tomb most likely built for a lesser noble. The body was preserved in the traditional fashion of mummification. Seventy days after his death, Tutankhamun's body was laid to rest and the tomb was sealed.
There are no known records of Tutankhamun after his death, and, as a result uncertainty still surrounds his death. He may have been assassinated, or died as the result of an injury received while hunting. until the 1920s. Even the location of his tomb was lost, as its entrance had been covered by the debris from a later-built tomb building.
