List of Abbasid caliphs

The Abbasid caliphs were the holders of the Islamic title of caliph who were members of the Abbasid dynasty, a branch of the Quraysh tribe descended from the uncle of the Islamic prophet Muhammad, Al-Abbas ibn Abd al-Muttalib.
The family came to power in the Abbasid Revolution in 748–750, supplanting the Umayyad Caliphate. They were the rulers of the Abbasid Caliphate, as well as the generally recognized ecumenical heads of Islam, until the 10th century, when the Shi'a Fatimid Caliphate and the Caliphate of Córdoba challenged their primacy. The political decline of the Abbasids had begun earlier, during the Anarchy at Samarra, which accelerated the fragmentation of the Muslim world into autonomous dynasties. The caliphs lost their temporal power in 936–946, first to a series of military strongmen and then to the Shi'a Buyid Emirs that seized control of Baghdad; the Buyids were in turn replaced by the Sunni Seljuk Turks in the mid-11th century, and Turkish rulers assumed the title of "Sultan" to denote their temporal authority. The Abbasid caliphs remained the generally recognized suzerains of Sunni Islam, however. In the mid-12th century, the Abbasids regained their independence from the Seljuks, but the revival of Abbasid power ended with the Sack of Baghdad by the Mongols in 1258.
Most Abbasid caliphs were born to a concubine mother, known as umm al-walad. The term refers to a slave woman who had a child from her owner; those women were renowned for their beauty and intelligence, in that the owner might recognize the legitimacy of his children from them to be legally free and with full rights of inheritance, and refrain from trading the mothers afterwards. Those concubines where from non-Muslim lands and brought to slavery in the Abbasid Caliphate via a number of different slave trade routes. The slave concubines mostly were Abyssinians, Armenians, Berbers, Byzantine Greeks, Turkish or even from Sicily.
