Ever since Minorsky published his introduction and commentary on the Safavid manual of administration Tadhkirat al-Mulūk, which has become a classic in the field, scholars have come to agree on the tribal character of the state that was founded by Shah Esma`il. In fact, it is through the military force of the Turkmen tribes, the Qezelbash, that Shah Esma`il was able to accede to the throne, thus inaugurating a period of relative stability for Iran that lasted more than two centuries. Iran owed its ability to resist the recurring and alternating attacks by the Ottoman Empire and the Uzbegs to Qezelbash power as well.

Initially mobilized by religious fanaticism, the military strength of the Qezelbash became a double-edged sword for the Safavid rulers with the waning of unconditional Qezelbash devotion to the shah. Though they were indispensable to the defense of the empire's frontiers, the Qezelbash amirs, with their unbridled despotism and the resulting turmoil, never ceased to be a prime source of concern for the rulers.
