Ayyubid dynasty named after Najm ad-Din Ayyub
History
Origins
The progenitor of the Ayyubid dynasty, Najm ad-Din Ayyub ibn Shadhi, belonged to the Kurdish Rawadiya tribe, itself a branch of the large Hadhabani tribe. Ayyub's ancestors settled in the town of Dvin, in northern Armenia. The Rawadiya were the dominant Kurdish group in the Dvin district, forming part of the political-military elite of the town.
Circumstances became unfavorable in Dvin when Turkish generals seized the town from its Kurdish prince. Shadhi left with his two sons Ayyub and Asad ad-Din Shirkuh. His friend Mujahid ad-Din Bihruz—the military governor of northern Mesopotamia under the Seljuks—welcomed him and appointed him governor of Tikrit. After Shadhi's death, Ayyub succeeded him in governance of the city with the assistance of his brother Shirkuh. Together they managed the affairs of the city well, gaining them popularity from the local inhabitants. In the meantime, Imad ad-Din Zangi, the ruler of Mosul, was defeated by the Abbasids under Caliph al-Mustarshid and Bihruz. In his bid to escape the battlefield to Mosul via Tikrit, Zangi took shelter with Ayyub and sought his assistance in this task. Ayyub complied and provided Zangi and his companions boats to cross the Tigris River and safely reach Mosul.As a consequence for assisting Zangi, the Abbasid authorities sought punitive measures against Ayyub. Simultaneously, in a separate incident, Shirkuh killed a close confidant of Bihruz on charges that he had sexually assaulted a woman in Tikrit. The Abbasid court issued arrest warrants for both Ayyub and Shirkuh, but before the brothers could be arrested, they departed Tikrit for Mosul in 1138. When they arrived in Mosul, Zangi provided them with all the facilities they needed and he recruited the two brothers into his service. Ayyub was made commander of Ba'albek and Shirkuh entered the service of Zangi's son, Nur ad-Din. According to historian Abdul Ali, it was under the care and patronage of Zangi that the Ayyubid family rose to prominence.
