An Atabeg was a title used in the medieval Islamic world, particularly in the context of the Seljuk Empire and later in the Ayyubid dynasty. It referred to a high-ranking official or military leader who acted as a guardian or regent for a young prince. The Atabeg was responsible for the education, training, and governance of the prince, often wielding significant power in their own right. The role of the Atabeg was crucial in maintaining stability and authority within the realm. They often commanded armies and managed territories, serving as both military leaders and political advisors. Notable Atabegs include Zengi, who played a key role in the Crusades, and Nureddin, who expanded his influence in the region.
