Question
What year did the Abbasid Revolution overthrow the Umayyad Caliphate?
Answer
750 CE, at the Battle of the Zab, where Abbasid forces defeated the last Umayyad caliph Marwan II.
Question
Who organised the military revolt that brought the Abbasids to power?
Answer
Abu Muslim, who built and led the Abbasid army from Khurasan starting in 747 CE; he was later executed by al-Mansur in 755 CE.
Question
What is a 'mawali' and why did their resentment matter?
Answer
A mawali is a non-Arab convert to Islam. Under the Umayyads they still paid extra taxes and had lower status despite converting — this broken promise of equality fuelled support for the Abbasid revolt.
Question
Why did the Abbasids found a new capital, and where?
Answer
Caliph al-Mansur founded Baghdad in 762 CE, moving the centre of power east into the old Persian heartland, symbolising the shift away from an Arab-only elite.
Question
Name two ways the Abbasid state differed from the Umayyad state.
Answer
1) Non-Arabs (especially Persians) could rise to high office. 2) Government adopted Persian bureaucratic practices (viziers, diwans) rather than an Arab-tribal model.
Question
What is the House of Wisdom (Bayt al-Hikma)?
Answer
A centre in Baghdad, closely linked to al-Ma'mun, where scholars translated Greek, Persian, and Indian texts and advanced fields like mathematics and astronomy — key to the Golden Age of Islam.
Question
Who was al-Khwarizmi and why is he significant?
Answer
A mathematician working in Baghdad's House of Wisdom whose work gives us the words 'algorithm' and 'algebra' — a symbol of Abbasid intellectual achievement.
Question
What civil war disrupted the transition between Harun al-Rashid and al-Ma'mun?
Answer
The war between brothers al-Amin and al-Ma'mun (809–813 CE) after Harun al-Rashid's death, showing succession instability even at the height of Abbasid power.
Question
Describe the process by which the Abbasids destroyed the Umayyad dynasty.
Answer
Abu Muslim's Khurasani army defeated Marwan II at the Battle of the Zab (750 CE); Abu al-Abbas ('al-Saffah') then had most of the Umayyad royal family hunted down and killed, with only one prince escaping to Spain.
Question
What warning sign shows that Abbasid prosperity was not the same as stability?
Answer
Succession wars (al-Amin vs al-Ma'mun), regional revolts, and growing reliance on Turkic slave-soldiers (mamluks) all existed alongside the Golden Age, planting seeds of future fragmentation.
Question
Compare Harun al-Rashid and al-Ma'mun's contributions to the Golden Age.
Answer
Harun al-Rashid (786–809) is remembered for peak court wealth, prestige, and diplomacy; al-Ma'mun (813–833) is more directly credited with formalising the House of Wisdom and sponsoring the great wave of scientific translation.
Question
What does 'end of Arab dominance' mean precisely in this period?
Answer
It does not mean Arabs lost power or Arabic lost its role in religion/law — it means Arab ethnicity stopped being a REQUIREMENT for status, and the empire became genuinely multi-ethnic and Islamic rather than Arab-tribal in identity.
