Baghdad is the capital of which caliphate?

• A. Abbasid Caliphate
• B. Umayyad Caliphate
• C. Fatimid Caliphate
• D. Seljuk Empire

Answer: (A)

Baghdad is most closely tied to the Abbasid Caliphate because the Abbasids established it as their capital, inaugurating a new era of centralized governance and cultural flourishing. After overthrowing the Umayyads, the Abbasid ruler al-Mansur founded Baghdad on the banks of the Tigris around 762 CE, turning it into the political and intellectual heart of the empire. This shift symbolized a break from the Umayyad capital in Damascus and set the stage for the Islamic Golden Age, with institutions like the House of Wisdom drawing scholars from across the Muslim world.

The other options don’t fit as the primary capital associated with Baghdad. The Umayyad Caliphate had Damascus as its capital, not Baghdad. The Fatimid Caliphate was centered in Ifriqiya and later Cairo, far to the west of Baghdad. The Seljuk Empire controlled Baghdad at times, but their realm was not defined by Baghdad as its fixed capital in the same way, and they preceded the Abbasid caliphs’ decline; the Abbasids remained the caliphs linked to Baghdad until the Mongol conquest. Thus, the Abbasid Caliphate is the correct association.
