What killed the sultan Saladin, who famously unified the Muslim world during the 12th century, recaptured Jerusalem from the Christians and helped spark the Third Crusade? Until now, it was a mystery. But by sifting through clues on Saladin's medical symptoms written more than 800 years ago, a doctor may have finally determined what illness felled the mighty sultan.

It was typhoid, said Dr. Stephen Gluckman, a professor of medicine at the University of Pennsylvania's Perelman School of Medicine, announced today (May 4) at the 25th annual Historical Clinicopathological Conference at the University of Maryland School of Medicine. Experts at the conference diagnose a historical figure every year, and past diagnoses have featured Lenin, Darwin, Eleanor Roosevelt and Lincoln.
