This wide-ranging study sets out to answer an unassumingly tricky question: What is politics in Islam? Paul L. Heck’s answer takes the form of a close analysis of sovereignty across Islamic history, approaching this concept from the perspective of political theology. As he illustrates, the history of politics in Islam is best understood as an ongoing struggle for a moral order between those who occupy positions of rulership and religious voices that communicate the ethics of Islam and educate the public in their religious and moral devotions. Heck shows that it is precisely through these interactions that Islamic conceptions of sovereignty are constructed and negotiated.
