The Abbasid Caliphate (/əˈbæsəd/ or /ˈæbəsəd/ Arabic: الخلافة العباسية‎ al-Khilāfah al-‘Abbāsīyah) was the third of the Islamic caliphates to succeed the Islamic prophet Muhammad. The Abbasid dynasty descended from Muhammad's youngest uncle, Abbas ibn Abd al-Muttalib (566–653 CE), from whom the dynasty takes its name.
