Arm und Reich
Harari first specialized in medieval history and military history in his studies from 1993 to 1998 at the Hebrew University of Jerusalem. He completed his PhD degree at Jesus College, Oxford, in 2002, under the supervision of Steven J. Gunn. From 2003 to 2005, he pursued postdoctoral studies in history as a Yad Hanadiv Fellow. While at Oxford, Harari first encountered the writings of Jared Diamond, whom he has acknowledged as an influence on his own writing. At a Berggruen Institute salon, Harari said that Diamond's "Guns, Germs, and Steel" “was kind of an epiphany in my academic career. I realized that I could actually write such books.”
