Book excerpt: The 'mirror for princes' genre of literature offers advice to a ruler, or ruler-to-be, concerning the exercise of royal power and the wellbeing of the body politic. This anthology presents selections from the 'mirror literature' produced in the Islamic Early Middle Period (roughly the tenth to twelfth centuries CE), newly translated from the original Arabic and Persian, as well as a previously translated Turkish example. In these texts, authors advise on a host of political issues which remain compelling to our contemporary world: political legitimacy and the ruler's responsibilities, the limits of the ruler's power and the limits of the subjects' duty of obedience, the maintenance of social stability, causes of unrest, licit and illicit uses of force, the functions of governmental offices and the status and rights of diverse social groups. Medieval Muslim Mirrors for Princes is a unique introduction to this important body of literature, showing how these texts reflect and respond to the circumstances and conditions of their era, and of ours.
