 | | All of these caliphs were descended from Abbas, a member of the tribe of Quraysh of Mecca who was an uncle of the prophet Muhammad. |
 | | The Abbasid caliphs officially based their claim to the throne on their descent from Abbas (AD 566-652), the eldest uncle of Muhammad, in virtue of which descent they regarded themselves as the rightful heirs of the Prophet as opposed to the Umayyads, the descendants of Umar. |
 | | In the reign of Marwan II this opposition culminated in the rebellion of Ibrahim the Imam, the fourth in descent from Abbas, who, supported by the province of Khorasan, achieved considerable successes, but was captured (AD 747) and died in prison (as some hold, assassinated). |
