Alexander the Great was accidently buried alive.
Alexander the Great died at the age of 32, having conquered and established the world's biggest land-based empire. It spanned the Balkans to Pakistan. Alexander became sick in 323 BC and appeared to die after 12 days of intense torment. His corpse, on the other hand, showed no indications of decay or decomposition for a whole six days. Alexander was thought to have suffered from the neurological illness Guillain-Barré Syndrome, according to modern experts. They believe he was just paralysed and intellectually aware when he "died." In other words, he was horrifyingly buried alive!
