"Noah Feldman tells the story behind the increasingly popular call for the establishment of the sharia--the law of the traditional Islamic state--in the modern Muslim world. Feldman goes back to the roots of classical Islamic law, under which executive power was balanced by the scholars who interpreted and administered the sharia. That balance was destroyed under Ottoman rule, resulting in the unchecked executive dominance that continues to distort politics in so many Muslim states. Feldman argues that a modern Islamic state could provide political and legal justice to today's Muslims through sharia--but only if new institutions emerge that restore this constitutional balance of power. In a new introduction, Feldman discusses developments in Egypt, Tunisia, Libya, and other Muslim-majority countries since the Arab Spring and describes how Islamists must meet the challenge of balance if the new Islamic states are to succeed."--P.
