Description

The Abbasid Caliphate (Arabic: الْخِلَافَةُ الْعَبَّاسِيَّة) was the third caliphate to succeed the Islamic prophet Muhammad. It was founded by a dynasty descended from the prophet's uncle, Abbas ibn Abdul-Muttalib (566–653 CE), from whom the dynasty takes its name. They ruled as caliphs for most of the caliphate from their capital in Baghdad in modern-day Iraq, after having overthrown the Umayyad Caliphate in the Abbasid Revolution of 750 CE (132 AH). The Abbasid Caliphate first centered its government in Kufa, modern-day Iraq, but in 762 the caliph Al-Mansur founded the city of Baghdad, near the ancient Babylonian capital city of Babylon. Baghdad became the center of science, culture and invention in what became known as the Golden Age of Islam. This, in addition to housing several key academic institutions, including the House of Wisdom, as well as a multiethnic and multi-religious environment, garnered it a worldwide reputation as the "Center of Learning".

Al-Mustansir Bi'llah (full name: Abû Ja`far al-Mustansir bi-llah al-Mansûr ben az-Zâhir Surname Al-Mustansir), (1192–1242) was the Caliph of the Abbasid dynasty from 1226 to 1242. He succeeded Caliph Az-Zahir in the year 1226 and was the penultimate caliph to rule from Baghdad.

The Ayyubid dynasty 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 Nur ad-Din of Syria, leading Nur ad-Din's army in battle against the Crusaders in Fatimid Egypt, where he was made Vizier. Following Nur ad-Din's death, Saladin was proclaimed as the first Sultan of Egypt and rapidly expanded the new sultanate beyond the frontiers of Egypt to encompass most of the Levant (including the former territories of Nur ad-Din), in addition to Hijaz, Yemen, northern Nubia, Tarabulus, Cyrenaica, southern Anatolia, and northern Iraq, the homeland of his Kurdish family. By virtue of his sultanate including Hijaz, the location of the Islamic holy cities of Mecca and Medina, he was the first ruler to be hailed as the Custodian of the Two Holy Mosques, a title that would be held by all subsequent Sultans of Egypt until the Ottoman conquest of 1517. Saladin's military campaigns in the first decade of his rule, aimed at uniting the various Arab and Muslim states in the region against the Crusaders, set the general borders and sphere of influence of the Sultanate of Egypt for almost three and a half centuries of its existence. Most of the Crusader states, including the Kingdom of Jerusalem, fell to Saladin after his victory at the Battle of Hattin in 1187. However, the Crusaders reconquered the coast of Palestine in the 1190s.
