Abu Muslim was born in the city of Balkh in the state of Khorasan. He still after more than 1200
hundred years remain to be a legendry and highly respected revolutionary figure.
There are different accounts of his origin and background by different sources but the definite
truth is that he was an ethnic Tajik of the state of Khorasan which was dominated by Tajiks at
the time. It was during his imprisonment for anti Umayyads activities that he met the Abbasid
imam who was also briefly incarcerated in 741. The Abbasid imam were set out to overthrow the
Umayyad dynasty so taking advantage of the situation Abu Muslim sided with Abbasids and led
to numerous revolts in Khorasan that eventually led to the demise of Umayyad dynasty.
Abu Muslim was an energetic and capable leader who overcome the initial resentment caused
among Arabs by his non-Arab origin. He very well took advantage of deep social division and
anti arab, and freedom seeking sentiments in Khorasan. He recruited from various discontented
and dispossessed social groups and created a coalition of rebellious Arabs and Khorasanians.
On June 15, 747, Abu Muslim raised the banner of revolution and the revolt quickly spread
throughout Khorasan and to other provinces. The revolt eventually led to the overthrow of
Umayyad caliph and the last Umayyad caliph, Marwan II was defeated and kill in 750. Abu
Muslim was the leading factor in defeat of Umayyads and rise of Abbasids. As as-Saffah became
the first Abbasid caliph in 749, Abu Muslim was given the governorship of Khorasan in reward
for his services. The Abbasids still depended on him on all affairs of the state specially the
military and political affairs.
The Abbasids were basically enthroned and to a great extend influenced by Abu Muslim as he was a leading politician, powerful military leader and a very popular figure in many provinces specially among non-arabs. As Abu Muslims's power and popularity grow the Abbasids became more and more suspicious of him specially that he was inclined to separate Khorasan from the rest of Abbasid states.
Al Mansur the second Abbasids Caliph was in fear of Abu Muslim's ever increasing popularity.
After having Abu Muslim quell an uprising by the uncle of Al Mansur, stripped away the
governorship of Khorasan from him. When Abu Muslim arrived at his invitation to his court, al
Mansur treacherously put him to death and in this way eliminated a potential rival for the throne
and the possibility of losing the province of Khorasan.
The unavenged and cowardly murder of Abu Muslim, a legendry hero among Khorasanians, inspired many later uprising against Abbasids.
