Of the 5,398 treasures from Tutankhamun's tomb at the Grand Egyptian Museum in Cairo, the ones that paint a picture of Tutankhamun's family are the most unsettling. Particularly intriguing are two tiny mummified babies. Now in the labs of the museum, they give a chilling insight into the bizarre practices that kept the Pharaoh's dynasty in power and ultimately lead to its downfall. DNA analysis reveals the foetuses are Tutankhamun's stillborn children - the offspring of an incestuous relationship between Tutankhamun and his sister. Similarly, DNA evidence suggests Tutankhamun was also the result of incest. Artefacts hidden for years in museum basements hint that he suffered genetic abnormalities and lived in constant pain. Golden slippers, rescued from almost certain disintegration by the Museum's conservators, reveal additional straps to hold the pharaoh's foot inside the shoe. Whilst the wear and tear on beautifully crafted walking sticks suggest he needed support for even simple tasks like walking. Could Tutankhamun's disability and the death of his unborn children be related? A genetics expert thinks so and shows how the royal family's incest magnified genetic weaknesses, which can cause conditions such as Tutankhamun's clubfoot and miscarriage. But Tutankhamun and his royal family weren't just afflicted by inbreeding - he also inherited a broken and failing Egypt from his father Akhenaten's disastrous attempt to change the religion of the country and build a new capital. A generation of children and young people died building Akhenaten's city in the desert and Egypt lost land to its enemies. It was a poisonous legacy that Tutankhamun tried to escape but failed. Tutankhamun died early at the age of 19, possibly at the head of his troops far from home. The evidence suggests his disability may have contributed to a fatal chariot accident. Thanks to the devastating deeds of his father, Tutankhamun was buried in a small tomb and quickly erased from official Egyptian history. But by a twist of fate, his fall from grace in ancient times meant he and his treasure would be reserved for posterity and he would become the most famous ruler of the ancient world.
