Dan Snow, Raksha Dave and John Sergeant retrace the final hundred days of Tutankhamun's life, working through what daily existence looked like for a teenage pharaoh who took the throne as a child and died at nineteen. The episode sits inside the wider series Tutankhamun: Life, Death and Legacy, and this installment turns to a puzzle that has nagged Egyptologists since Howard Carter's 1922 discovery: why the boy king's tomb in the Valley of the Kings is so much smaller and plainer than those built for other New Kingdom rulers. The presenters visit excavation sites and examine tomb architecture and burial goods on camera, weighing theories about a rushed burial, a sudden death, and possible political maneuvering by the officials who succeeded him. Interviews with archaeologists and historians anchor the speculation in physical evidence from the tomb itself, including its cramped layout compared to neighboring royal burials. The result is a focused look at how a single architectural anomaly can reopen questions about a reign otherwise known mainly through its famous grave goods.
