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".

Al-Hasan bin Wahhas
Al- Hasan bin Wahhas( d. February, 1285) was an imam of the Zaidi state in Yemen who ruled in 1258- 1260.
The previous imam al- Mahdi Ahmad bin al- Husayn made a number of enemies among the Zaidi elite during his lifetime, which eventually resulted in his violent death in the Battle of Shuwaba in 1258.
One of the claimants for the imamate was Abu Muhammad al- Hasan bin Wahhas, who belonged to the Hamzite Sharifs, descendants of imam al- Muhtasib al- Mujahid Hamzah( d. 1066).
He was acknowledged as imam by part of the Zaidis.
Personally, he was described as dashing in warfare and an excellent horseman.
Another claimant was Shams ad- Din Ahmad who formally submitted to the suzerainty of the Rasulid sultan, the main power in Yemen at this time.
The two would- be imams shared the properties and fortresses of the Zaidi lands between them.
In the same year, Shams ad- Din and two of his brothers succumbed to an epidemic, leaving al- Hasan bin Wahhas as the holder of the imamate.
However, he soon fell out with Shams ad- Din's brother Sarim ad- Din Da'ud( d. 1290).
Sarim ad- Din colluded with the Rasulid prince Asad ad- Din and met al- Hasan bin Wahhas in battle at Asafir in 1260.
While the imam's forces fled, al- Hasan remained fighting on the battlefield until taken prisoner.
Sarim ad- Din kept the imam imprisoned until 1269.
Much later, in 1284, Sarim ad- Din tried unsuccessfully to enlist the support of al- Hasan to fight the Rasulids.
The ex-imam died shortly afterwards, in February 1285.

Saif ad- Din Ghazi I( died 1149) was the Emir of Mosul from 1146 to 1149.
He was the eldest son of Imad ad- Din Zengi of Mosul, and the elder brother of Nur ad- Din.
In 1146 Imad ad- Din Zengi was besieging the fortress of Qal Ja'bari when he was assassinated on September 15 by one of his servants who wanted to escape punishment.
His forces were scattered, but Imad ad- Din Zengi's two sons were able to regain control and to divide informally the empire:
Saif ad- Din succeeded him in Mosul and the Jezirah( northern Iraq) while Nur ad- Din succeeded in Aleppo.
Saif ad- Din had first to fight to secure his position in Mosul.
Two years before, the Seljuk sultan Ghiyath ad- Din Mas'ud had named his cadet son Alp- Arslan as overlord of Zengi, but the latter had neutralized him and carried with him at the siege.
At Zengi's death, Alp- Arslan tried to exploit the ensuing disorder to gain the power in Mosul.
Two of Zengi's advisors, the head of the diwan al- Din Muhammad Jemal and" hajab" Amir Salah al- Din Muhammad al- Yaghisiyani took the side of Saif ad- Din: taking advantage of the inexperience of the young Seljuk, giving Saif ad- Din the time necessary to take control of Mosul.
When Alp Arslan appeared in Mosul, he was arrested and imprisoned in the citadel.
In 1148, together with Nur ad- Din, he marched south to help defend Damascus during the Second Crusade( see Siege of Damascus).
The atabeg of the city, Mu'in ad- Din Unur, however refused them entrance, using the presence of Zangi's sons to convince the Franks to release the siege.
He died in November 1149 and was succeeded by another brother, Qutb ad- Din Mawdud.
