After the decline of the Fatimids (episode 61), the medieval Middle East entered a period called the Sunni Revival, in which Shi’ism was officially discouraged and Shi’i institutions were closed and replaced with Sunni institutions. Or, at least, that’s what the official chroniclers tell us. The buildings themselves tell us a different story–one that tries to bring decades of conflict to an end by accommodating different beliefs. Art Historian Stephennie Mulder has spent the past decade working in Syria and shares a new look at history of Sunni and Shi’a in Syria during the medieval period; and how both histories are threatened by ISIS and the Syrian Civil War.
