Nasîhatnâme (Ottoman Turkish: نصيحت نامه, Naṣīḥat-nāme) were a type of guidance letter for Ottoman sultans, similar to mirrors for princes. They draw on a variety of historical and religious sources, and were influenced by the governance of previous empires such as the Seljuk Turks or the Mongols, as well as by early Muslim history and by contemporary events.
