atabë
Atabeg (or atabë) was a noble title originating in the Seljuk Empire. It was initially granted to military leaders who were responsible for the upbringing and education of young princes, hence the meaning of the word, which translates roughly to "father of the prince." These atabegs often wielded significant political power, acting as regents and governors while the princes were underage.
Over time, the title evolved and became a hereditary position in many regions of the Middle East
