Mujir ad-Din Abaq
Mujīr ad- Dīn ʿ Abd al- Dawla Abu Saʿīd Ābaq ibn Jamāl ad- Dīn Muhammad( died 1169) was the governor of Damascus from 1140 to 1154.
He was the eldest son of Jamal ad- Din Muhammad.
After the death of his father in 1140, Mujir ad- Din succeeded his father as governor in 1140.
As he was still a minor, Mu'in ad- Din Unur was named vizier.
Zengi attacked Damascus, hoping to take advantage of Jamal ad- Din's death, but Mu'in ad- Din effectively organized the defense of the city.
When this regent died in July 1149, Mujir ad- Din took his place as the rightful heir of Damascus.
He was a weak ruler, however, and Damascus came under the influence of Nur ad- Din Zangi, emir of Aleppo and Mosul, who had imposed his dominance over the city in the aftermath of the Second Crusade.
In 1150 Nur ad- Din recognized Mujir ad- Din as ruler of Damascus, but in 1151 Mujir ad- Din allied with the crusaders against Bosra, angering Nur ad- Din.
Later that year Mujir ad- Din visited Aleppo and swore to remain loyal to Nur ad- Din.
In 1152 Mujir ad- Din again besieged Bosra, until the governor of the city agreed to his demands and he returned to Damascus.
In 1153 Mujir ad- Din joined Nur ad- Din in the capture of the crusader castle at Baniyas.
In 1154 the two were in conflict again, and Nur ad- Din finally occupied Damascus by force, exiling Mujir ad- Din to Homs.
Nur ad- Din was fully in control of the city and all of Syria.
Mujir ad- Din later left Homs for Baghdad.
His honorific title" Mujīr ad- Dīn" means" protector of the faith".
