Tutankhamun was one of the 18th Egyptian pharaohs in the ancient history of Egypt. Pharaoh was Egypt from 1334 to 1325 BC. In the era of the modern state. Tutankhamun is considered one of the most famous pharaohs for reasons not related to his achievements or victories, as is the case with many Pharaohs, but for other reasons that are historically important, most notably the discovery of his tomb and treasures without any damage. And the mystery surrounding the circumstances of his death, since many considered the death of Pharaoh at a very early age is abnormal, especially with the presence of traces of fractures in the bones of the thigh and skull, and the marriage of his minister from his widow after his death and installed himself Pharaoh. All these mysterious events, and the heavy use of the legend of the Pharaohs curse associated with the tomb of Tutankhamun, used in films and video games made Tutankhamun the most famous pharaohs of mysteries and questions still unanswered, considered by some to be the oldest assassinations in human history. Tutankhamun died young and was buried in his tomb - Tomb 62 - in the Valley of the Kings. Tutankhamun was 9 years old when he became Pharaoh of Egypt and his name in the ancient Egyptian language means "the living image of God Amon," the great old Egyptian goddess. Tutankhamun lived in a transitional period in the history of Ancient Egypt where he came after Akhenaten, who tried to unify the ancient gods of Egypt in the form of the One God on Sunday. In his reign, he returned to worship the ancient gods of Egypt. His tomb was discovered in 1922 in the Valley of the Kings by British archaeologist Howard Carter. The discovery triggered a widespread media uproar in the world
