Nur al-Din Zengi in the context of "Ayyubid dynasty"

The Zengid or Zangid dynasty, also referred to as the Atabegate of Mosul, Aleppo and Damascus (Arabic: أتابكة الموصل وحلب ودمشق), or the Zengid State (Old Anatolian Turkish: ظانغى دولتی, Modern Turkish: Zengî Devleti; Arabic: الدولة الزنكية, romanized: al-Dawla al-Zinkia) was initially an Atabegate of the Seljuk Empire created in 1127. It formed a Turkoman dynasty of Sunni Muslim faith, which ruled parts of the Levant and Upper Mesopotamia, and eventually seized control of Egypt in 1169. Imad ad-Din Zengi was the first ruler of the dynasty. In 1174, the Zengid state extended from Tripoli to Hamadan and from Yemen to Sivas, as it also included the Egyptian territories held by Saladin as governor in the name of Nur al-Din Zengi.

The Zengid Atabegate became famous in the Islamic world for its successes against the Crusaders, and for being the Atabegate from which Saladin originated. Following the demise of the Seljuk dynasty in 1194, the Zengids persisted for several decades as one of the "Seljuk successor-states" until 1250.

The Ayyubid dynasty (Arabic: الأيوبيون, romanized: al-Ayyūbīyūn), also known as the Ayyubid Sultanate, was a Sunni Muslim Kurdish dynasty that founded the medieval Sultanate of Egypt, which was established by Saladin in 1171, following his abolition of the Fatimid Caliphate. Saladin had originally served the Zengid ruler Nur al-Din, leading the latter's army against the Crusaders in Fatimid Egypt, where he was made vizier. Following the death of his Zengid suzerain Nur al-Din in 1174, Saladin was proclaimed as the first Sultan of Egypt by the Abbasid Caliphate, and rapidly expanded the new sultanate beyond Egypt to encompass most of Syria, in addition to Hejaz, Yemen, northern Nubia, Tripolitania and Upper Mesopotamia. Saladin's military campaigns set the general borders and sphere of influence of the sultanate of Egypt for the almost 350 years of its existence. Most of the Crusader states fell to Saladin after his victory at the Battle of Hattin in 1187, but the Crusaders reconquered the Syrian coastlands in the 1190s.

After Saladin's death in 1193, his sons contested control of the sultanate, but Saladin's brother al-Adil ultimately became sultan in 1200. All of the later Ayyubid sultans of Egypt were his descendants. In the 1230s, the emirs of Syria attempted to assert their independence from Egypt and the Ayyubid realm remained divided until Sultan as-Salih Ayyub restored its unity by subduing most of Syria, except Aleppo, by 1247. By then, local Muslim dynasties had driven out the Ayyubids from Yemen, the Hejaz, and parts of Mesopotamia. After his death in 1249, as-Salih Ayyub was succeeded in Egypt by his son al-Mu'azzam Turanshah. However, the latter was soon overthrown by his Mamluk generals who had repelled a Crusader invasion of the Nile Delta. This effectively ended Ayyubid power in Egypt. Attempts by the emirs of Syria, led by an-Nasir Yusuf of Aleppo, to wrest back Egypt failed. In 1260, the Mongols sacked Aleppo and conquered the Ayyubids' remaining territories soon after. The Mamluks, who expelled the Mongols, maintained the Ayyubid principality of Hama until deposing its last ruler in 1341.
