Background and early life
According to
Al-Suyuti's ''
History of the Caliphs'', Al-Mansur lived 95 AH – 158 AH (714 CE – 6 October 775 CE). Al-Mansur was born at the home of the Abbasid family in
Humeima (modern-day

His mother was
Sallamah, a
Berber slave woman. Al-Mansur was a brother of
Saffah.
Both were named Abd Allah, and to distinguish between them, Saffah was referred to by his ''

Al-Mansur was a great-grandson of
Abbas ibn Abd al-Muttalib, an uncle of the Islamic prophet,
Muhammad

. Al-Mansur's brother Saffah began asserting his claim to become caliph in the 740s and became particularly active in
Khorasan, an area where non-Arab Muslims lived. After the death of the Umayyad caliph
Hisham ibn Abd al-Malik in 743 a period of instability followed. Saffah led the
Abbasid Revolution in 747 and his claim to power was supported throughout Iraq by Muslims. He became the first caliph of the

Shortly before the overthrow of the

Abbasids, the last Umayyad Caliph
Marwan II, arrested the head of the Abbasid family, Al Mansur's other brother Ibrahim. Al-Mansur fled with the rest of his family to
Kufa where some of the Khorasanian rebel leaders gave their allegiance to his brother Saffah. Ibrahim died in captivity and Saffah became the first Abbasid Caliph. During his brother's reign, Al-Mansur led an army to

But then their power passed to their effeminate sons, whose only ambition was the satisfaction of their desires and who chased after pleasures forbidden by Almighty God...Then God stripped them of their power, covered them with shame and deprived them of their worldly goods".[

Execution of Abu Muslim and aftermath
Fearing the power of the Abbasid army general Abu Muslim, who gained in popularity among the people, Al-Mansur carefully planned his assassination. Abu Muslim was conversing with the Caliph when, at an appointed signal, four (some sources say five) of his guards rushed in and fatally wounded the general. John Aikin, in his work ''General Biography'', narrates that Mansur, not content with the assassination, committed "outrages on the dead body, and kept it several days in order to glut his eyes with the spectacle."
The Execution of Abu Muslim caused uproars throughout the province of Khorasan. In 755 Sunpadh
Sunpadh ( fa, سندپاد; also spelled Sunpad and Sunbadh) was an Iranian nobleman from the House of Karen, who incited an uprising against the Abbasid Caliphate in the 8th century.

. In Ray, he seized the treasuries of Abu Muslim. He gained many supporters from Jibal and Tabaristan, including the Dabuyid ruler, Khurshid, who was paid with money from the treasures. Al-Mansur ordered a force of 10,000 under Abbasid commander Jahwar ibn Marrar al-lijli to march without delay to Khorasan to fight the rebellion. Sunpadh was defeated and Khorasan reclaimed by the Abbasids.[
Al-Mansur sent an official to take inventory of the spoils collected from the battle as a precautionary measure against acquisition by his army. Angered by Al-Mansur's avarice, general Jahwar gained support from his troops for his plans to split the treasures evenly, and revolted against the caliph. This raised alarm in the caliph's court and Al-Mansur ordered Mohammad ibn Ashar to march towards Khorasan. Jahwar, knowing his troops were at a disadvantage, retired to Isfahan and fortified in preparation. Mohammad's army pressed the rebel forces and Jahwar fled to ]Azerbaijan

After relieving former vizier ibn Attiya al-Bahili, Al-Mansur transferred his duties to Abu Ayyub al-Muriyani from Khuzestan. Abu Ayyub was previously a secretary to Sulayman ibn Habib ibn al-Muhallab, who in the past, had condemned Al-Mansur to be whipped and flogged to pieces. Abu Ayyub had rescued Al-Mansur from this punishment. Nevertheless, after appointing him as vizier, Al-Mansur suspected Abu Ayyub of various crimes, including extortion and treachery, which led to the latter's assassination. The vacant secretary role was granted to Aban ibn Sadaqa until the death of the caliph Al-Mansur.[

For when sleep fell upon his eyes, his spirit remained awake.” Notably frugal, Al-Mansur was nicknamed Abu al-Duwaneek (“the Father of Small Change”), kept close tabs on his tax collectors, and made sure public spending was carefully monitored.

Death
Al-Masudi writes that Mansur died on Saturday 6, Dhu al-Hijja 158 AH/775 CE. There are varying accounts of the location and circumstances of Al-Mansur's death. One account narrates that Al-Mansur was on a pilgrimage to Mecca and had nearly reached, when death overtook him at a location called the Garden of the Bani Amir on the high road to Iraq at the age of sixty-three. According to this narration, he was buried in Mecca with his face uncovered because he was wearing the ihram clothing. 100 graves were dug around Mecca with the intention to thwart any attempt to find and violate his bones.
A different narration from Fadl ibn Rabi'ah, who claimed to have been with Mansur at his time of death, states that he died at al-Batha' near the Well of Maimun in which he would have been buried at al-Hajun at sixty-five years of age. In this narration, Mansur was sitting in a domed room hallucinating about ill-omen writings on the wall. When Al-Rabiah replied "I see nothing written on the wall. Its surface is clean and white," Al-Mansur replied, "my soul is warned that she may prepare for her near departure." After reaching the Well of Maimun, he reportedly said "God be praised" and succumbed to death that very day.
When al-Mansur died, the caliphate's treasury contained 600,000,000 dirhams and fourteen million dinars.[ On his deathbed, Mansur said, “We have sacrificed the life to come for a mere dream!”]
