Alp Arslan ibn Mahmud
Alp Arslan ibn Mahmud was ruler of Mosul from 1127- 1146.
As son of Mahmud II, he was appointed governor of Mosul in 1127 with Zengi as his atabeg.
While governor in name only, Alp aspired to replace Ghiyath ad- Din Mas’ud as sultan upon his death.
In 1145, Alp conspired to kill Zengi ’s deputy Naşīr al- Dīn Jaqar and take control of Mosul.
His co-conspirator was likely Farrukh- Shāh ibn Mahmūd, who provided assurances that the army would support Alp.
Naşīr was killed by Alp, Farrukh or their followers( according to different sources), and his head thrown for effect towards Zengi ’s forces.
" Qadi" Taj al- Din Yahya ibn Shahrazuri encouraged
Alp to take control of the citadel at Mosul, escorting him there, where he and his followers were arrested by Zengi loyalists.
Zengi dispatched his commander Zain- ad- Din ‘ Ali Küchük to control the situation.
The conspirators were executed and Alp was kept close to Zengi until his death in 1146.
Alp Arslan was then replaced by Zengi ’s son Saif ad- Din Ghazi I who had him imprisoned.
Muhammad I Tapar
Muhammad I (also known as Ghiyath ad-Din Muhammad or Muhammad Tapar, died 1118) was a son of Seljuq Sultan Malik Shah I.
In Turkish, Tapar means "he who obtains, finds".
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".
Izz ad-Din Mas'ud
Izz ad- Din Mas'ud I bin Mawdud( Izz ad Din Bin Qutb ad- Din Mawdud Bin Imad ud- Din Zengi; Arabic: عز الدين مسعود بن مودود; died 1193) was a Zengid emir of Mosul.
Saif ad-Din Ghazi I
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.
Nur ad-Din Arslan Shah I
Nur ad- Din Arslan Shah I( or Arslan Shah) was the Zengid Emir of Mossul 1193 – 1211.
He was successor of Izz ad- Din Mas'ud.
Ghiyath ad-Din Mas'ud
Ghiyath ad-Din Mas'ud (1108 – September 13, 1152) was the Seljuq Sultan of Iraq and western Persia in 1133–1152.
He was the son of sultan Muhammad I Tapar.
At the age of twelve (1120–1121), he rebelled unsuccessfully against his elder brother, Mahmud II, who however forgave him.
At Mahmud's death in 1131, the power was contended between Mahmud's son, Dawud, Mas'ud, whose powerbase was in Iraq, Seljuq-Shah (in Fars and Khuzistan) and Toghrul II.
In 1133 Mas'ud was able to obtain recognition as sultan from the emirs of Baghdad, and to receive the investiture by caliph al-Mustarshid.
Toghrul, who controlling the eastern provinces of the western Seljuq, launched a military campaign but was defeated by Mas'ud in May 1133.
Toghrul died in 1134.
Also in 1133 Mas'ud supported Zengi, besieged by al-Mustarshid's troops in Mosul.
In 1135 caliph al-Mustarshid contested his authority but, on 14 June of that year, he was defeated and made prisoner at Daimarg, between Hamadan and Baghdad, and killed two months later by the Hashshashins.
As al-Mustarshid's successor, al-Rashid, also rebelled with the support of Zengi, Mas'ud besieged him in Baghdad, forcing him to flee to Mosul, where he was also killed by the Hashshashins.
Although able to ensure control over Iraq, Mas'ud's power over the rest of the Suljuq empire was uncertain: apart from Khorasan and Transoxiana, which had been long time under the control of his uncle Ahmed Sanjar, Dawud kept control over Azerbaijan for several years, while weastern Persia was effectively ruled by emir Bozaba until Mas'ud defeated him, together with other emirs, in 1147.
In 1148 Mas'ud faced another coalition against him, this time aiming to place Malik Shah on the throne in his place.
During his troublesome reign, Mas'ud was forced to accept to delegate his authority to numerous emirs with the Iqta', a tax institution which reduced the imperial incomes.
Other became effectively independent sultans, such as Zengi.
This caused, according to historian ibn al-Athir, the beginning of the steep decline of the Seljuq Empire.
Mas'ud died at Hamadan in 1152.
He was briefly succeeded by Malik Shah, who had been forgiven by Mas'ud, and also given one the sultan's daughters as spouse.
Ghazi II Saif ud-Din
Saif ud- Din Ghazi II; full name: Saif ad- Din Ghazi II Bin Mawdud Bin Imad ad- Din Atabeg Zengi; died 1180) was a Zangid Emir of Mosul, the nephew of Nur ad- Din Zengi.
He became Emir of Mosul in 1170 after the death of his father Qutb ad- Din Mawdud.
Saif had been chosen as the successor under the advice of eunuch ’ Abd al- Masish, who wanted to keep the effective rule in lieu of the young emir; the disinherited son of Mawdud, Imad ad- Din Zengi II, fled to Aleppo at the court of Nur ad- Din.
The latter, who was waiting for an excuse to annex Mosul, conquered Sinjar in September 1170 and besieged Mosul, which surrendered on 22 January 1171.
After ousting al- Masish, he put Gümüshtekin, one of his officers, as governor, leaving Saif ud- Din nothing but the nominal title of emir.
The latter also married the daughter of Nur ad- Din.
At Nur ad- Din's death( May 1174), Gümüshtekin went to Damascus to take control of his son and entitled himself of atabeg of Aleppo.
Saif ud- Din rejected his tutorage and restored his independence.
The nobles of Damascus, worried by Gümüshtekin's increasing power, offered Saif ud- Din their city, but he could not intervene since he was busy in retaking Mosul.
Thenceforth Damascus was given to Saladin.
Saladin took control of Biladu- Sham( Syria) but Saif ud- Din wanted to take over Aleppo, so he sent his brother Izz ad- Din Mas'ud at the head of an army to fight Saladin: they met in an area near Hama called Kron Hama( Arabic: قرون حماه) where Saif ud- Din was defeated.
Later he prepared for another battle at Tell al- Sultan( Arabic: تل سلطان) near Aleppo, where he was also defeated; he went back to Mosul and sent messengers to Saladin offering his alliance, which was accepted.
Saif ud- Din died from tuberculosis, and his brother Izz ad- Din Mas'ud succeeded him in 1180.
