At the beginning of Tutankhamun’s reign, everything had changed. He had restored the old religion worshipping all of the Gods instead of worshipping the Sun God Ra. Given his age, the king probably had very powerful advisers, presumably including General Horemheb, the Vizier Ay, and Maya, the “Overseer of the Treasury”. Horemheb records that the king appointed him “lord of the land” as hereditary prince to maintain law. He also noted his ability to calm the young king when his temper flared.
In his third regnal year, Tutankhamun reversed several changes made during his father’s reign. He ended the worship of the god Aten and restored the god Amun to supremacy. The ban on the cult of Amun was lifted and traditional privileges were restored to its priesthood. The capital was moved back to Thebes and the city of Akhetaten abandoned. This is also when he changed his name to Tutankhamun.
As part of his restoration, the king initiated building projects, in particular at Thebes and Karnak, where he dedicated a temple to Amun. Many monuments were erected, and an inscription on his tomb door declares the king had “spent his life in fashioning the images of the gods”. The traditional festivals were now celebrated again, including those related to the Apis Bull, Horemakhet, and Opet.
