中央アジア / The Birth and Expansion of Islam 3 / 6

The Umayyad and Abbasid Dynasties

In 661, Muawiya became caliph and founded the Umayyad Dynasty. Later, the Abbasid Dynasty was established in 750, transforming the Islamic world into an empire that promoted “equality for all.”

Umayyad Dynasty (661–750)

  • Capital: Damascus (Syria)
  • Preference for Arabs: Arab Muslims monopolized politics and the military, while non-Arab converts (mawali) were discriminated against
  • Largest territory: expanded to Spain (the Iberian Peninsula), Central Asia, and western India
  • 732: defeated by the Frankish Kingdom at the Battle of Tours and Poitiers, stopping expansion into Western Europe

Abbasid Dynasty (750–1258)

  • Abolished preference for Arabs and appointed non-Arabs such as Persians and Turks, becoming an “Islamic empire”
  • Capital: Baghdad (built in 762). A planned circular city
  • The caliph was a symbol of religious authority, while the vizier managed practical affairs through a Persian-style bureaucracy
  • The 8th–9th centuries were the height of prosperity. Trade, scholarship, and cities flourished
Example Question ①
State the greatest difference between the rule of the Umayyad and Abbasid dynasties.
Answer: The Umayyad Dynasty favored Arab Muslims and discriminated against non-Arab converts (mawali), adopting an Arab nationalist policy. The Abbasid Dynasty treated people equally regardless of ethnicity as long as they converted to Islam, actively appointed Persian officials, and presented itself as an “Islamic empire of equality for all.”
Example Question ②
Why was Baghdad called the “circular city”?
Answer: Baghdad, built in 762 by Caliph al-Mansur, was called the “circular city” because it was a planned city with concentric walls centered on the caliph’s palace. Located at an important transportation point along the Tigris River, it is said to have had a population of more than one million at its height.
Key Points
  • Umayyad Dynasty: capital Damascus, preference for Arabs, largest territory reaching Spain
  • The Battle of Tours and Poitiers in 732 prevented expansion into Europe
  • Abbasid Dynasty: capital Baghdad, ethnic equality, Persian-style bureaucracy
  • Dissatisfaction among the mawali (non-Arab converts) contributed to the Abbasid Revolution
