Hayrettin Yücesoy, professor of Islamic and Arabic studies at Washington University in St. Louis, takes us back to the political and theological debates of 9th-century Baghdad. Scholars later claimed that in the medieval Islamic world, religion and politics fit neatly together. However, as Yücesoy explains, the historical reality was much more complicated. Religious scholars, political leaders, and even elite anarchists all had competing ideas about the relationship between Muslim faith and politics.
