Until about 1800, the West and the Islamic realm were like two adjacent, parallel universes, each assuming itself to be the center of the world while ignoring the other. As Europeans colonized the globe, the two world histories intersected and the Western narrative drove the other one under. The West hardly noticed, but the Islamic world found the encounter profoundly disrupting.This book reveals the parallel "other" narrative of world history to help us make sense of today's world conflicts. Ansary traces the history of the Muslim world from pre-Mohammedan days through 9/11, introducing people, events, empires, legends, and religious disputes, both in terms of what happened and how it was understood and interpreted.
