Final answer:
Historians concluded that Tutankhamun had a fractured skull after first viewing X-rays in 1968, but it was not the cause of his death.
Step-by-step explanation:
After first viewing x-rays of Tutankhamun's skull in 1968, historians reached the conclusion that the pharaoh, who died at a young age, had a fractured skull. This discovery led to theories about the cause of Tutankhamun's death, with some suggesting that he suffered a fatal blow to the head. However, further research and analysis have since shown that the fracture likely occurred during the mummification process and was not the cause of his death.
