Region of Palestine was conqueredby the Islamic Empire following the 636 CE Battle of Yarmouk during the Muslim conquest of Syria, and the Muslims gave relief from burdensome Roman taxes and religious persecution of Christian heretics. The country was incorporated into Bilad al - Sham Province as military districts of Urdunn and Filastin. In 661 CE, with the assassination of Ali, Muawiyah I became the uncontested Caliph of the Islamic World after being crowned in Jerusalem. In 691, the Dome of the Rock became the world 's first great work of Islamic architecture. The Umayyads were replaced by the Abbasids in 750. From 878 Palestine was ruled from Egypt by semi-autonomous rulers for almost a century, beginning with Ahmad ibn Tulun and ending with the Ikhshidid rulers who were both buried in Jerusalem. The Fatimids conquered the region in 969. In 1073, Palestine was captured by the Great Seljuq Empire, only to be recaptured by the Fatimids in 1098, who then lost the region to the Crusaders in 1099. Crusader control of Jerusalem and most of Palestine as the Kingdom of Jerusalem lasted almost a century until defeat by Saladin 's forces in 1187, after which most of Palestine became controlled by the Ayyubids. A rump Crusader state in the northern coastal cities survived for another century, but despite seven further Crusades, the Crusaders were no longer a significant power in the region. The Mamluk Sultanate was indirectly created in Egypt as a result of the Seventh Crusade. The Mongol Empire reached Palestine for the first time in 1260, beginning with the raids into the Levant under Nestorian Christian general Kitbuqa and reaching an apex at the pivotal Battle of Ain Jalut. In 1486, hostilities broke out between the Mamluks and the Ottoman Turks and the Ottomans captured Mamluk Palestine and Syria in 1516.
