What did Tutankhamun do that was important?

Answer 1

During Tutankhamen's reign, Akhenaten's Amarna revolution (Atenism) was being reversed. Akhenaten had attempted to supplant the traditional priesthood and deities with a god who was until then considered minor, Aten. In Year 3 of Tutankhamen's reign (1331 BC), when he was still a boy of about eleven and probably under the influence of two older advisor's (Akhenaten's vizier Ay and perhaps Nefertiti), the ban on the old pantheon of deities and their temples was lifted, the traditional privileges were restored to their priesthoods, and the capital was moved back to Thebes. The young pharaoh adopted the name Tutankhamen, changing it from his birth name Tutankhamen. Because of his age at the time these decisions were made, it is generally thought that most if not all the responsibility for them falls on his advisor's. Also, King Tutankhamen restored all of the traditional deities and restored order to the chaos that his relative had caused. Many temples devoted to Amun-Ra were built. Tutankhamen's wooden box depicts him going to war against Hittites and Nubian's suggesting that he may have gone to war in the last few years of his reign, and perhaps even died from injuries suffered in the campaign.
