Though little known to western audiences, the Arab invasions of 634-638 into Syria and the Levant were some of the most consequential in history. What began as small-scale raiding of frontier Byzantine garrisons soon transitioned to full-scale war, featuring a decisive victory of the Byzantine army at the Battle of Yarmuk in 636 and the capture of Jerusalem in 638. The surrender of the Holy City enabled Muslim control of the Temple Mount within it and the construction of two of the most famous sites for all of Islam: the al-Aqsa Mosque and the Dome of the Rock. Following the conquest of Syria, their armies would go on to conquer Egypt, Persia, Mesopotamia, North Africa, and Iberia—by 711, over half of the old Roman Empire lived in the Abode of Islam.
