Alexander III of Macedon, commonly known as Alexander the Great, was a king of the ancient Greek kingdom of Macedon. Having accomplished so much at an early age, it was unfortunate that he died at just 32. 

Some historians say Alexander died of malaria or other natural causes while others believe he was poisoned.

But, new theories have suggested that Alexander might have been alive when he was buried. 

In 323 BC, Alexander fell ill and, after 12 days of excruciating pain, he seemingly passed away.

However, his corpse didn’t show any signs of rot or decomposition for a whole six days.

Modern-day scientists believe Alexander suffered from the neurological disorder Guillain-Barré Syndrome.

They believe that when he “died” he was actually just paralyzed and mentally aware. Basically, he was horrifically buried alive!
