Ayyubid dynasty

The Ayyubid dynasty (Arabic: الأيوبيون, romanized: al-Ayyūbīyūn), also known as the Ayyubid Sultanate, was the founding dynasty of the medieval Sultanate of Egypt established by Saladin in 1171, following his abolition of the Fatimid Caliphate of Egypt. A Sunni Muslim of Kurdish origin, 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 Nur al-Din's death, 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 Hijaz, 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.

Despite their relatively short tenure, the Ayyubid dynasty had a transformative effect on the region, particularly Egypt. Under the Ayyubids, Egypt, which had previously been a formally Shia caliphate, became the dominant Sunni political and military force, and the economic and cultural centre of the region, a status that it would retain until it was conquered by the Ottomans in 1517. Throughout the sultanate, Ayyubid rule ushered in an era of economic prosperity, and the facilities and patronage provided by the Ayyubids led to a resurgence in intellectual activity in the Islamic world. This period was also marked by an Ayyubid process of vigorously strengthening Sunni Muslim dominance in the region by constructing numerous madrasas (Islamic schools of law) in their major cities.

In medieval Islamic sources, the Ayyubids were referred to as the "Kurdish regime/dynasty" (Arabic: دولة الکردية, romanized: Dawlat al-Kurdiyya), the "dynasty/regime of the Kurds" (Arabic: دولة الأکراد, romanized: Dawlat al-Akrād), or as the "Kurdish Kingdom" (Arabic: المملکة الحصينة الأکرادية, romanized: al-Mamlaka al-Ḥasina al-Akrādiyya ). For example, Muhammad ibn Ibrahim al-Khazraji, a writer at the end of the Ayyubid period, wrote a history entitled Tar'īkh al-Dawlat al-Akrād wal-Atrāk ("The history of the State of the Kurds and of the Turks"). The Kurds meant the Ayyubids while Turks where the Mamluks, who succeeded the Ayyubids of Egypt in 1250. They were also referred to as "Ayyubid Kurds" (Arabic: الأکراد الأيوبية al-Akrād al-Ayyūbiyya) and "Kurdish rulers of Egypt".

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 part of the political-military elite of the town.

Circumstances became unfavorable in Dvin when Turks seized the town. 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.

In 1164, Nur al-Din dispatched Shirkuh to lead an expeditionary force to prevent the Crusaders from establishing a strong presence in an increasingly anarchic Egypt. Shirkuh enlisted Ayyub's son, Saladin, as an officer under his command. They successfully drove out Dirgham, the vizier of Egypt, and reinstated his predecessor Shawar. After being reinstated, Shawar ordered Shirkuh to withdraw his forces from Egypt, but Shirkuh refused, claiming it was Nur al-Din's will that he remain. Over the course of several years, Shirkuh and Saladin defeated the combined forces of the Crusaders and Shawar's troops, first at Bilbais, then at a site near Giza, and in Alexandria, where Saladin would stay to protect while Shirkuh pursued Crusader forces in Lower Egypt.
