Abstract: The military administration of the Seljuks was clearly distinguished, which contributed to their appearance on the scene of events as a military force that had its influence. Al-Rwandi described the Seljuks as people who were distinguished by piety, religion, vigilance, and non-negligence, and that the military system was the basis on which the Seljuk sultans relied in achieving their political goals and seized vast lands and properties. This necessitated the presence of the army in order to take appropriate measures in the fight and achieve the goals of the fight.
