Fast Conquest, Slow Conversion
Arab armies swiftly took Egypt, Syria, Iraq, and Iran. The eastern Roman empire lost vast territories. Yet conquests did not bring instant conversion.
Non-Muslims held the status of dhimmi:
- Protected and subordinate
- Permitted their own law and worship
- Liable to a poll tax, the jizya
Governors in Umayyad Egypt discouraged conversion because converts stopped paying tax. A Muslim majority took roughly 100 to 300 years to emerge across the empire.
| Period | Dates | Capital | Character |
|---|---|---|---|
| Rashidun | 632–661 | Medina | Conquests and first civil war |
| Umayyad | 661–750 | Damascus | Arab ruling caste |
| Abbasid | 750–1258 | Baghdad | Cosmopolitan empire |
The Abbasid revolution of 750 broke the Arab monopoly on power. The capital moved east to the Tigris.
Scholars translated Greek texts into Arabic to build new scholarship:
- Al-Khwarizmi developed algebra and the algorithm.
- Ibn Sina wrote a medical canon taught in Europe for centuries.
- Ibn Rushd wrote commentaries on Aristotle that shaped Latin thought.
Al-Andalus and Islamic Authority
Al-Andalus developed independently under an Umayyad dynasty. Abd al-Rahman III declared a caliphate in 929. Civil war later fractured the realm into rival taifa kingdoms.
Christian kingdoms pushed south over centuries. They broke Almohad power at Las Navas de Tolosa in 1212. The final Muslim stronghold, Granada, fell in 1492.
Authority without a Church
Islamic governance differed fundamentally from Western Christendom:
- There is no clergy and no formal church hierarchy.
- Authority rests with the ulama, scholars recognized for their learning.
- Rulers cannot capture or invest religious offices.
Common pitfall: Viewing Poitiers in 732 as saving Europe from conquest. Charles Martel defeated a raid, not an invasion of Gaul. Muslim forces held Narbonne until 759 before withdrawing.
