~Chronology

622 Muhammad and his followers flee from persecution in Mecca and establish the first independent Muslim community in Medina. The beginning of the Islamic era is calculated from this event, known as the Hijrah (Hegira).
632 Muhammad dies in Medina. Muslim leadership passes to four close associates, known as caliphs, who oversee the rapid growth of an Islamic empire: Egypt, Syria, Iraq, and Iran are conquered.
661 The caliphate passes to the Umayyad dynasty. The capital of the empire moves to Damascus, Syria. Spain, North Africa, Central Asia, and part of India are conquered.
691 The Dome of the Rock is completed on the Temple Mount in Jerusalem, a site identified with Muhammadís night journey to heaven. It is the oldest surviving Muslim building.
750 The caliphate passes to the Abbasid dynasty, descended from the Prophetís uncle, al-'Abbas. New capitals, including Baghdad, are founded in Iraq.
756 A member of the Umayyad dynasty, 'Abd al- Rahman, escapes to Spain, where his descendants rule from their capital at Córdoba until 1031.
909 A rival caliphate is established in North Africa by the Fatimids, descended from the Prophetís daughter, Fatimah, and her husband, 'Ali.
945 The Abbasid caliph in Baghdad is reduced to a religious figurehead after the Buyid family gains control of Iraq and Iran.
969 A Fatimid army conquers Egypt, where Cairo is founded as the new capital.
1055 Seljuk Turks from Central Asia conquer Baghdad.
1071 The Seljuks defeat the Byzantines in Anatolia, and the Turks begin to occupy what is now Turkey.

1171 Salah al-Din (Saladin) gains control of Egypt and replaces the Fatimid caliphate with his ownAyyubid dynasty. In 1187 he recaptures Jerusalem.
1250 The Ayyubids are replaced by sultans drawn from the dynasty's own household troops, known as Mamluks, who rule from Cairo until 1517.
1258 Mongol invaders led by Hulagu Khan, grandson of Chinggis (Genghis) Khan, conquer Baghdad and kill the last Abbasid caliph. Hulagu’s descendants, the Ilkhanids, rule Iraq, Iran, and parts of Anatolia until 1335.
