The Abbasid dynasty or Abbasids (Arabic: بنو العباس, romanized: Banu Abbas) were an Arab clan descended from Abbas ibn Abd al-Muttalib, that became the ruling family of the Caliphate, and thus the supreme heads of the Islamic world between 750 and 1258. The Abbasid Caliphate is divided into three main periods: Early Abbasid era (750–861), Middle Abbasid era (861–936) and Later Abbasid era (936–1258). The cadet branch of dynasty also ruled as ceremonial rulers for the Mamluk Sultanate (1261–1517).
